# Accounts on Docker Hub
|
||||
|
||||
## Docker Hub accounts
|
||||
|
||||
You can `search` for Docker images and `pull` them from [Docker
|
||||
Hub](https://hub.docker.com) without signing in or even having an
|
||||
account. However, in order to `push` images, leave comments or to *star*
|
||||
a repository, you are going to need a [Docker
|
||||
Hub](https://hub.docker.com) account.
|
||||
|
||||
### Registration for a Docker Hub account
|
||||
|
||||
You can get a [Docker Hub](https://hub.docker.com) account by
|
||||
[signing up for one here](https://hub.docker.com/account/signup/). A valid
|
||||
email address is required to register, which you will need to verify for
|
||||
account activation.
|
||||
|
||||
### Email activation process
|
||||
|
||||
You need to have at least one verified email address to be able to use your
|
||||
[Docker Hub](https://hub.docker.com) account. If you can't find the validation email,
|
||||
you can request another by visiting the [Resend Email Confirmation](
|
||||
https://hub.docker.com/account/resend-email-confirmation/) page.
|
||||
|
||||
### Password reset process
|
||||
|
||||
If you can't access your account for some reason, you can reset your password
|
||||
from the [*Password Reset*](https://hub.docker.com/account/forgot-password/)
|
||||
page.
|
||||
|
||||
## Organizations and groups
|
||||
|
||||
A Docker Hub organization contains public and private repositories just like
|
||||
a user account. Access to push, pull or create these organisation owned repositories
|
||||
is allocated by defining groups of users and then assigning group rights to
|
||||
specific repositories. This allows you to distribute limited access
|
||||
Docker images, and to select which Docker Hub users can publish new images.
|
||||
|
||||
### Creating and viewing organizations
|
||||
|
||||
You can see what organizations [you belong to and add new organizations](
|
||||
https://hub.docker.com/account/organizations/) from the Account Settings
|
||||
tab. They are also listed below your user name on your repositories page
|
||||
and in your account profile.
|
||||
|
||||

|
||||
|
||||
### Organization groups
|
||||
|
||||
Users in the `Owners` group of an organization can create and modify the
|
||||
membership of groups.
|
||||
|
||||
Unless they are the organization's `Owner`, users can only see groups of which they
|
||||
are members.
|
||||
|
||||

|
||||
|
||||
### Repository group permissions
|
||||
|
||||
Use organization groups to manage the users that can interact with your repositories.
|
||||
|
||||
You must be in an organization's `Owners` group to create a new group, Hub
|
||||
repository, or automated build. As an `Owner`, you then delegate the following
|
||||
repository access rights to groups:
|
||||
|
||||
| Access Right | Description |
|
||||
|--------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
|
||||
| `Read` | Users with this right can view, search, and pull a private repository. |
|
||||
| `Write` | Users with this right can push to non-automated repositories on the Docker Hub. |
|
||||
| `Admin` | Users with this right can modify a repository's "Description", "Collaborators" rights. They can also mark a repository as unlisted, change its "Public/Private" status and "Delete" the repository. Finally, `Admin` rights are required to read the build log on a repo. |
|
||||
| | |
|
||||
|
||||
Regardless of their actual access rights, users with unverified email addresses
|
||||
have `Read` access to the repository. Once they have verified their address,
|
||||
they have their full access rights as granted on the organization.

# Automated Builds on Docker Hub
|
||||
|
||||
## About Automated Builds
|
||||
|
||||
*Automated Builds* are a special feature of Docker Hub which allow you to
|
||||
use [Docker Hub's](https://hub.docker.com) build clusters to automatically
|
||||
create images from a GitHub or Bitbucket repository containing a `Dockerfile`
|
||||
The system will clone your repository and build the image described by the
|
||||
`Dockerfile` using the directory the `Dockerfile` is in (and subdirectories)
|
||||
as the build context. The resulting automated image will then be uploaded
|
||||
to the Docker Hub registry and marked as an *Automated Build*.
|
||||
|
||||
Automated Builds have several advantages:
|
||||
|
||||
* Users of *your* Automated Build can trust that the resulting
|
||||
image was built exactly as specified.
|
||||
* The `Dockerfile` will be available to anyone with access to
|
||||
your repository on the Docker Hub registry.
|
||||
* Because the process is automated, Automated Builds help to
|
||||
make sure that your repository is always up to date.
|
||||
* Not having to push local Docker images to Docker Hub saves
|
||||
you both network bandwidth and time.
|
||||
|
||||
Automated Builds are supported for both public and private repositories
|
||||
on both [GitHub](http://github.com) and [Bitbucket](https://bitbucket.org/).
|
||||
|
||||
To use Automated Builds, you must have an [account on Docker Hub](
|
||||
https://docs.docker.com/userguide/dockerhub/#creating-a-docker-hub-account)
|
||||
and on GitHub and/or Bitbucket. In either case, the account needs
|
||||
to be properly validated and activated before you can link to it.
|
||||
|
||||
The first time you to set up an Automated Build, your
|
||||
[Docker Hub](https://hub.docker.com) account will need to be linked to
|
||||
a GitHub or Bitbucket account.
|
||||
This will allow the registry to see your repositories.
|
||||
|
||||
If you have previously linked your Docker Hub account, and want to view or modify
|
||||
that link, click on the "Manage - Settings" link in the sidebar, and then
|
||||
"Linked Accounts" in your Settings sidebar.
|
||||
|
||||
## Automated Builds from GitHub
|
||||
|
||||
If you've previously linked your Docker Hub account to your GitHub account,
|
||||
you'll be able to skip to the [Creating an Automated Build](#creating-an-automated-build).
|
||||
|
||||
### Linking your Docker Hub account to a GitHub account
|
||||
|
||||
> *Note:*
|
||||
> Automated Builds currently require *read* and *write* access since
|
||||
> [Docker Hub](https://hub.docker.com) needs to setup a GitHub service
|
||||
> hook. We have no choice here, this is how GitHub manages permissions, sorry!
|
||||
> We do guarantee nothing else will be touched in your account.
|
||||
|
||||
To get started, log into your Docker Hub account and click the
|
||||
"+ Add Repository" button at the upper right of the screen. Then select
|
||||
[Automated Build](https://registry.hub.docker.com/builds/add/).
|
||||
|
||||
Select the [GitHub service](https://registry.hub.docker.com/associate/github/).
|
||||
|
||||
When linking to GitHub, you'll need to select either "Public and Private",
|
||||
or "Limited" linking.
|
||||
|
||||
The "Public and Private" option is the easiest to use,
|
||||
as it grants the Docker Hub full access to all of your repositories. GitHub
|
||||
also allows you to grant access to repositories belonging to your GitHub
|
||||
organizations.
|
||||
|
||||
By choosing the "Limited" linking, your Docker Hub account only gets permission
|
||||
to access your public data and public repositories.
|
||||
|
||||
Follow the onscreen instructions to authorize and link your
|
||||
GitHub account to Docker Hub. Once it is linked, you'll be able to
|
||||
choose a source repository from which to create the Automatic Build.
|
||||
|
||||
You will be able to review and revoke Docker Hub's access by visiting the
|
||||
[GitHub User's Applications settings](https://github.com/settings/applications).
|
||||
|
||||
> **Note**: If you delete the GitHub account linkage that is used for one of your
|
||||
> automated build repositories, the previously built images will still be available.
|
||||
> If you re-link to that GitHub account later, the automated build can be started
|
||||
> using the "Start Build" button on the Hub, or if the webhook on the GitHub repository
|
||||
> still exists, will be triggered by any subsequent commits.
|
||||
|
||||
### Auto builds and limited linked GitHub accounts.
|
||||
|
||||
If you selected to link your GitHub account with only a "Limited" link, then
|
||||
after creating your automated build, you will need to either manually trigger a
|
||||
Docker Hub build using the "Start a Build" button, or add the GitHub webhook
|
||||
manually, as described in [GitHub Service Hooks](#github-service-hooks).
|
||||
|
||||
### Changing the GitHub user link
|
||||
|
||||
If you want to remove, or change the level of linking between your GitHub account
|
||||
and the Docker Hub, you need to do this in two places.
|
||||
|
||||
First, remove the "Linked Account" from your Docker Hub "Settings".
|
||||
Then go to your GitHub account's Personal settings, and in the "Applications"
|
||||
section, "Revoke access".
|
||||
|
||||
You can now re-link your account at any time.
|
||||
|
||||
### GitHub organizations
|
||||
|
||||
GitHub organizations and private repositories forked from organizations will be
|
||||
made available to auto build using the "Docker Hub Registry" application, which
|
||||
needs to be added to the organization - and then will apply to all users.
|
||||
|
||||
To check, or request access, go to your GitHub user's "Setting" page, select the
|
||||
"Applications" section from the left side bar, then click the "View" button for
|
||||
"Docker Hub Registry".
|
||||
|
||||

|
||||
|
||||
The organization's administrators may need to go to the Organization's "Third
|
||||
party access" screen in "Settings" to Grant or Deny access to the Docker Hub
|
||||
Registry application. This change will apply to all organization members.
|
||||
|
||||

|
||||
|
||||
More detailed access controls to specific users and GitHub repositories would be
|
||||
managed using the GitHub People and Teams interfaces.
|
||||
|
||||
### Creating an Automated Build
|
||||
|
||||
You can [create an Automated Build](
|
||||
https://registry.hub.docker.com/builds/github/select/) from any of your
|
||||
public or private GitHub repositories that have a `Dockerfile`.
|
||||
|
||||
Once you've selected the source repository, you can then configure:
|
||||
|
||||
- The Hub user/org the repository is built to - either your Hub account name,
|
||||
or the name of any Hub organizations your account is in
|
||||
- The Docker repository name the image is built to
|
||||
- If the Docker repository should be "Public" or "Private"
|
||||
You can change the accessibility options after the repository has been created.
|
||||
If you add a Private repository to a Hub user, then you can only add other users
|
||||
as collaborators, and those users will be able to view and pull all images in that
|
||||
repository. To configure more granular access permissions, such as using groups of
|
||||
users or allow different users access to different image tags, then you need
|
||||
to add the Private repository to a Hub organization that your user has Administrator
|
||||
privilege on.
|
||||
- If you want the GitHub to notify the Docker Hub when a commit is made, and thus trigger
|
||||
a rebuild of all the images in this automated build.
|
||||
|
||||
You can also select one or more
|
||||
- The git branch/tag, which repository sub-directory to use as the context
|
||||
- The Docker image tag name
|
||||
|
||||
You can set a description for the repository by clicking "Description" link in the righthand side bar after the automated build - note that the "Full Description" will be over-written next build from the README.md file.
|
||||
has been created.
|
||||
|
||||
### GitHub private submodules
|
||||
|
||||
If your GitHub repository contains links to private submodules, you'll get an
|
||||
error message in your build.
|
||||
|
||||
Normally, the Docker Hub sets up a deploy key in your GitHub repository.
|
||||
Unfortunately, GitHub only allows a repository deploy key to access a single repository.
|
||||
|
||||
To work around this, you need to create a dedicated user account in GitHub and attach
|
||||
the automated build's deploy key that account. This dedicated build account
|
||||
can be limited to read-only access to just the repositories required to build.

### GitHub service hooks
|
||||
|
||||
The GitHub Service hook allows GitHub to notify the Docker Hub when something has
|
||||
been committed to that git repository. You will need to add the Service Hook manually
|
||||
if your GitHub account is "Limited" linked to the Docker Hub.
|
||||
|
||||
Follow the steps below to configure the GitHub Service hooks for your Automated Build:

|

|
||||
## Automated Builds with Bitbucket
|
||||
|
||||
In order to setup an Automated Build, you need to first link your
|
||||
[Docker Hub](https://hub.docker.com) account with a Bitbucket account.
|
||||
This will allow the registry to see your repositories.
|
||||
|
||||
To get started, log into your Docker Hub account and click the
|
||||
"+ Add Repository" button at the upper right of the screen. Then
|
||||
select [Automated Build](https://registry.hub.docker.com/builds/add/).
|
||||
|
||||
Select the [Bitbucket source](
|
||||
https://registry.hub.docker.com/associate/bitbucket/).
|
||||
|
||||
Then follow the onscreen instructions to authorize and link your
|
||||
Bitbucket account to Docker Hub. Once it is linked, you'll be able
|
||||
to choose a repository from which to create the Automatic Build.
|
||||
|
||||
### Creating an Automated Build
|
||||
|
||||
You can [create an Automated Build](
|
||||
https://registry.hub.docker.com/builds/bitbucket/select/) from any of your
|
||||
public or private Bitbucket repositories with a `Dockerfile`.
|
||||
|
||||
### Adding a Hook
|
||||
|
||||
When you link your Docker Hub account, a `POST` hook should get automatically
|
||||
added to your Bitbucket repository. Follow the steps below to confirm or modify the
|
||||
Bitbucket hooks for your Automated Build:
|
||||
|
||||
<table class="table table-bordered">
|
||||
<thead>
|
||||
<tr>
|
||||
<th>Step</th>
|
||||
<th>Screenshot</th>
|
||||
<th>Description</th>
|
||||

|
||||
registry.hub.docker.com/hooks/bitbucket.</td>
|
||||
</tr>
|
||||
</tbody>
|
||||
</table>
|
||||
|
||||
|
||||
## The Dockerfile and Automated Builds
|
||||
|
||||
During the build process, Docker will copy the contents of your `Dockerfile`.
|
||||
It will also add it to the [Docker Hub](https://hub.docker.com) for the Docker
|
||||
community (for public repositories) or approved team members/orgs (for private
|
||||
repositories) to see on the repository page.
|
||||
|
||||
### README.md
|
||||
|
||||
If you have a `README.md` file in your repository, it will be used as the
|
||||
repository's full description.The build process will look for a
|
||||
`README.md` in the same directory as your `Dockerfile`.
|
||||
|
||||
> **Warning:**
|
||||
> If you change the full description after a build, it will be
|
||||
> rewritten the next time the Automated Build has been built. To make changes,
|
||||
> modify the `README.md` from the Git repository.
|
||||
|
||||
## Remote Build triggers
|
||||
|
||||
If you need a way to trigger Automated Builds outside of GitHub or Bitbucket,
|
||||
you can set up a build trigger. When you turn on the build trigger for an
|
||||
Automated Build, it will give you a URL to which you can send POST requests.
|
||||
This will trigger the Automated Build, much as with a GitHub webhook.
|
||||
|
||||
Build triggers are available under the Settings menu of each Automated Build
|
||||
repository on the Docker Hub.
|
||||
|
||||

|
||||
|
||||
You can use `curl` to trigger a build:
|
||||
|
||||
```
|
||||
$ curl --data "build=true" -X POST https://registry.hub.docker.com/u/svendowideit/testhook/trigger/be579c
|
||||
82-7c0e-11e4-81c4-0242ac110020/
|
||||
OK
|
||||
```
|
||||
|
||||
> **Note:**
|
||||
> You can only trigger one build at a time and no more than one
|
||||
> every five minutes. If you already have a build pending, or if you
|
||||
> recently submitted a build request, those requests *will be ignored*.
|
||||
> To verify everything is working correctly, check the logs of last
|
||||
> ten triggers on the settings page .
|
||||
|
||||
## Webhooks
|
||||
|
||||
Automated Builds also include a Webhooks feature. Webhooks can be called
|
||||
after a successful repository push is made. This includes when a new tag is added
|
||||
to an existing image.
|
||||
|
||||
The webhook call will generate a HTTP POST with the following JSON
|
||||
payload:
|
||||
|
||||
```
|
||||
{
|
||||
"callback_url": "https://registry.hub.docker.com/u/svendowideit/testhook/hook/2141b5bi5i5b02bec211i4eeih0242eg11000a/",

|

}
|
||||
}
|
||||
```
|
||||
|
||||
Webhooks are available under the Settings menu of each Repository.
|
||||
Use a tool like [requestb.in](http://requestb.in/) to test your webhook.
|
||||
|
||||
> **Note**: The Docker Hub servers use an elastic IP range, so you can't
|
||||
> filter requests by IP.
|
||||
|
||||
### Webhook chains
|
||||
|
||||
Webhook chains allow you to chain calls to multiple services. For example,
|
||||
you can use this to trigger a deployment of your container only after
|
||||
it has been successfully tested, then update a separate Changelog once the
|
||||
deployment is complete.
|
||||
After clicking the "Add webhook" button, simply add as many URLs as necessary
|
||||
in your chain.
|
||||
|
||||
The first webhook in a chain will be called after a successful push. Subsequent
|
||||
URLs will be contacted after the callback has been validated.
|
||||
|
||||
### Validating a callback
|
||||
|
||||
In order to validate a callback in a webhook chain, you need to
|
||||
|
||||
1. Retrieve the `callback_url` value in the request's JSON payload.
|
||||
1. Send a POST request to this URL containing a valid JSON body.
|
||||
|
||||
> **Note**: A chain request will only be considered complete once the last
|
||||
> callback has been validated.
|
||||
|
||||
To help you debug or simply view the results of your webhook(s),
|
||||
view the "History" of the webhook available on its settings page.
|
||||
|
||||
### Callback JSON data
|
||||
|
||||
The following parameters are recognized in callback data:
|
||||
|
||||
* `state` (required): Accepted values are `success`, `failure` and `error`.
|
||||
If the state isn't `success`, the webhook chain will be interrupted.
|
||||
* `description`: A string containing miscellaneous information that will be
|
||||
available on the Docker Hub. Maximum 255 characters.
|
||||
* `context`: A string containing the context of the operation. Can be retrieved
|
||||
from the Docker Hub. Maximum 100 characters.
|
||||
* `target_url`: The URL where the results of the operation can be found. Can be
|
||||
retrieved on the Docker Hub.
|
||||
|
||||
*Example callback payload:*
|
||||
|
||||
{
|
||||
"state": "success",
|
||||
"description": "387 tests PASSED",
|
||||
"context": "Continuous integration by Acme CI",
|
||||
"target_url": "http://ci.acme.com/results/afd339c1c3d27"
|
||||
}
|
||||
|
||||
## Repository links
|
||||
|
||||
Repository links are a way to associate one Automated Build with
|
||||
another. If one gets updated, the linking system triggers a rebuild
|
||||
for the other Automated Build. This makes it easy to keep all your
|
||||
Automated Builds up to date.
|
||||
|
||||
To add a link, go to the repository for the Automated Build you want to
|
||||
link to and click on *Repository Links* under the Settings menu at
|
||||
right. Then, enter the name of the repository that you want have linked.
|
||||
|
||||
> **Warning:**
|
||||
> You can add more than one repository link, however, you should
|
||||
> do so very carefully. Creating a two way relationship between Automated Builds will
|
||||
> cause an endless build loop.

# Official Repositories on Docker Hub
|
||||
|
||||
The Docker [Official Repositories](http://registry.hub.docker.com/official) are
|
||||
a curated set of Docker repositories that are promoted on Docker Hub. They are
|
||||
designed to:
|
||||
|
||||
* Provide essential base OS repositories (for example,
|
||||
[`ubuntu`](https://registry.hub.docker.com/_/ubuntu/),
|
||||
[`centos`](https://registry.hub.docker.com/_/centos/)) that serve as the
|
||||
starting point for the majority of users.
|
||||
|
||||
* Provide drop-in solutions for popular programming language runtimes, data
|
||||
stores, and other services, similar to what a Platform-as-a-Service (PAAS)
|
||||
would offer.
|
||||
|
||||
* Exemplify [`Dockerfile` best practices](/articles/dockerfile_best-practices)
|
||||
and provide clear documentation to serve as a reference for other `Dockerfile`
|
||||
authors.
|
||||
|
||||
* Ensure that security updates are applied in a timely manner. This is
|
||||
particularly important as many Official Repositories are some of the most
|
||||
popular on Docker Hub.
|
||||
|
||||
* Provide a channel for software vendors to redistribute up-to-date and
|
||||
supported versions of their products. Organization accounts on Docker Hub can
|
||||
also serve this purpose, without the careful review or restrictions on what
|
||||
can be published.
|
||||
|
||||
Docker, Inc. sponsors a dedicated team that is responsible for reviewing and
|
||||
publishing all Official Repositories content. This team works in collaboration
|
||||
with upstream software maintainers, security experts, and the broader Docker
|
||||
community.
|
||||
|
||||
While it is preferable to have upstream software authors maintaining their
|
||||
corresponding Official Repositories, this is not a strict requirement. Creating
|
||||
and maintaining images for Official Repositories is a public process. It takes
|
||||
place openly on GitHub where participation is encouraged. Anyone can provide
|
||||
feedback, contribute code, suggest process changes, or even propose a new
|
||||
Official Repository.
|
||||
|
||||
## Should I use Official Repositories?
|
||||
|
||||
New Docker users are encouraged to use the Official Repositories in their
|
||||
projects. These repositories have clear documentation, promote best practices,
|
||||
and are designed for the most common use cases. Advanced users are encouraged to
|
||||
review the Official Repositories as part of their `Dockerfile` learning process.
|
||||
|
||||
A common rationale for diverging from Official Repositories is to optimize for
|
||||
image size. For instance, many of the programming language stack images contain
|
||||
a complete build toolchain to support installation of modules that depend on
|
||||
optimized code. An advanced user could build a custom image with just the
|
||||
necessary pre-compiled libraries to save space.
|
||||
|
||||
A number of language stacks such as
|
||||
[`python`](https://registry.hub.docker.com/_/python/) and
|
||||
[`ruby`](https://registry.hub.docker.com/_/ruby/) have `-slim` tag variants
|
||||
designed to fill the need for optimization. Even when these "slim" variants are
|
||||
insufficient, it is still recommended to inherit from an Official Repository
|
||||
base OS image to leverage the ongoing maintenance work, rather than duplicating
|
||||
these efforts.
|
||||
|
||||
## How can I get involved?
|
||||
|
||||
All Official Repositories contain a **User Feedback** section in their
|
||||
documentation which covers the details for that specific repository. In most
|
||||
cases, the GitHub repository which contains the Dockerfiles for an Official
|
||||
Repository also has an active issue tracker. General feedback and support
|
||||
questions should be directed to `#docker-library` on Freenode IRC.
|
||||
|
||||
## How do I create a new Official Repository?
|
||||
|
||||
From a high level, an Official Repository starts out as a proposal in the form
|
||||
of a set of GitHub pull requests. You'll find detailed and objective proposal
|
||||
requirements in the following GitHub repositories:
|
||||
|
||||
* [docker-library/official-images](https://github.com/docker-library/official-images)
|
||||
|
||||
* [docker-library/docs](https://github.com/docker-library/docs)
|
||||
|
||||
The Official Repositories team, with help from community contributors, formally
|
||||
review each proposal and provide feedback to the author. This initial review
|
||||
process may require a bit of back and forth before the proposal is accepted.
|
||||
|
||||
There are also subjective considerations during the review process. These
|
||||
subjective concerns boil down to the basic question: "is this image generally
|
||||
useful?" For example, the [`python`](https://registry.hub.docker.com/_/python/)
|
||||
Official Repository is "generally useful" to the large Python developer
|
||||
community, whereas an obscure text adventure game written in Python last week is
|
||||
not.
|
||||
|
||||
When a new proposal is accepted, the author becomes responsible for keeping
|
||||
their images up-to-date and responding to user feedback. The Official
|
||||
Repositories team becomes responsible for publishing the images and
|
||||
documentation on Docker Hub. Updates to the Official Repository follow the same
|
||||
pull request process, though with less review. The Official Repositories team
|
||||
ultimately acts as a gatekeeper for all changes, which helps mitigate the risk
|
||||
of quality and security issues from being introduced.
|
||||
|
||||
> **Note**: If you are interested in proposing an Official Repository, but would
|
||||
> like to discuss it with Docker, Inc. privately first, please send your
|
||||
> inquiries to partners@docker.com. There is no fast-track or pay-for-status
|
||||
> option.

# Your Hub repositories
|
||||
|
||||
Docker Hub repositories make it possible for you to share images with co-workers,
|
||||
customers or the Docker community at large. If you're building your images internally,
|
||||
either on your own Docker daemon, or using your own Continuous integration services,
|
||||
you can push them to a Docker Hub repository that you add to your Docker Hub user or
|
||||
organization account.
|
||||
|
||||
Alternatively, if the source code for your Docker image is on GitHub or Bitbucket,
|
||||
you can use an "Automated build" repository, which is built by the Docker Hub
|
||||
services. See the [automated builds documentation](./builds.md) to read about
|
||||
the extra functionality provided by those services.
|
||||
|
||||

|
||||
|
||||
Your Docker Hub repositories have a number of useful features.
|
||||
|
||||
## Stars
|
||||
|
||||
Your repositories can be starred and you can star repositories in
|
||||
return. Stars are a way to show that you like a repository. They are
|
||||
also an easy way of bookmarking your favorites.
|
||||
|
||||
## Comments
|
||||
|
||||
You can interact with other members of the Docker community and maintainers by
|
||||
leaving comments on repositories. If you find any comments that are not
|
||||
appropriate, you can flag them for review.
|
||||
|
||||
## Collaborators and their role
|
||||
|
||||
A collaborator is someone you want to give access to a private
|
||||
repository. Once designated, they can `push` and `pull` to your
|
||||
repositories. They will not be allowed to perform any administrative
|
||||
tasks such as deleting the repository or changing its status from
|
||||
private to public.
|
||||
|
||||
> **Note:**
|
||||
> A collaborator cannot add other collaborators. Only the owner of
|
||||
> the repository has administrative access.
|
||||
|
||||
You can also assign more granular collaborator rights ("Read", "Write", or "Admin")
|
||||
on Docker Hub by using organizations and groups. For more information
|
||||
see the [accounts documentation](accounts/).
|
||||
|
||||
## Private repositories
|
||||
|
||||
Private repositories allow you to have repositories that contain images
|
||||
that you want to keep private, either to your own account or within an
|
||||
organization or group.
|
||||
|
||||
To work with a private repository on [Docker
|
||||
Hub](https://hub.docker.com), you will need to add one via the [Add
|

Repository](https://registry.hub.docker.com/account/repositories/add/)
|
||||
link. You get one private repository for free with your Docker Hub
|
||||
account. If you need more accounts you can upgrade your [Docker
|
||||
Hub](https://registry.hub.docker.com/plans/) plan.
|
||||
|
||||
Once the private repository is created, you can `push` and `pull` images
|
||||
to and from it using Docker.
|
||||
|
||||
> *Note:* You need to be signed in and have access to work with a
|
||||
> private repository.
|
||||
|
||||
Private repositories are just like public ones. However, it isn't
|
||||
possible to browse them or search their content on the public registry.
|
||||
They do not get cached the same way as a public repository either.
|
||||
|
||||
It is possible to give access to a private repository to those whom you
|
||||
designate (i.e., collaborators) from its Settings page. From there, you
|
||||
can also switch repository status (*public* to *private*, or
|
||||
vice-versa). You will need to have an available private repository slot
|
||||
open before you can do such a switch. If you don't have any available,
|
||||
you can always upgrade your [Docker
|
||||
Hub](https://registry.hub.docker.com/plans/) plan.
|
||||
|
||||
## Webhooks
|
||||
|
||||
A webhook is an HTTP call-back triggered by a specific event.
|
||||
You can use a Hub repository webhook to notify people, services, and other
|
||||
applications after a new image is pushed to your repository (this also happens
|
||||
for Automated builds). For example, you can trigger an automated test or
|
||||
deployment to happen as soon as the image is available.
|
||||
|
||||
To get started adding webhooks, go to the desired repository in the Hub,
|
||||
and click "Webhooks" under the "Settings" box.
|
||||
A webhook is called only after a successful `push` is
|
||||
made. The webhook calls are HTTP POST requests with a JSON payload
|
||||
similar to the example shown below.
|
||||
|
||||
*Example webhook JSON payload:*
|
||||
|
||||
```
|
||||
{
|
||||
"callback_url": "https://registry.hub.docker.com/u/svendowideit/busybox/hook/2141bc0cdec4hebec411i4c1g40242eg110020/",
|

||||

||||

|
||||

|
||||
"status": "Active"
|
||||
}
|
||||
```
|
||||
|
||||
<TODO: does it tell you what tag was updated?>
|
||||
|
||||
For testing, you can try an HTTP request tool like [requestb.in](http://requestb.in/).
|
||||
|
||||
> **Note**: The Docker Hub servers use an elastic IP range, so you can't
|
||||
> filter requests by IP.
|
||||
|
||||
### Webhook chains
|
||||
|
||||
Webhook chains allow you to chain calls to multiple services. For example,
|
||||
you can use this to trigger a deployment of your container only after
|
||||
it has been successfully tested, then update a separate Changelog once the
|
||||
deployment is complete.
|
||||
After clicking the "Add webhook" button, simply add as many URLs as necessary
|
||||
in your chain.
|
||||
|
||||
The first webhook in a chain will be called after a successful push. Subsequent
|
||||
URLs will be contacted after the callback has been validated.
|
||||
|
||||
### Validating a callback
|
||||
|
||||
In order to validate a callback in a webhook chain, you need to
|
||||
|
||||
1. Retrieve the `callback_url` value in the request's JSON payload.
|
||||
1. Send a POST request to this URL containing a valid JSON body.
|
||||
|
||||
> **Note**: A chain request will only be considered complete once the last
|
||||
> callback has been validated.
|
||||
|
||||
To help you debug or simply view the results of your webhook(s),
|
||||
view the "History" of the webhook available on its settings page.
|
||||
|
||||
#### Callback JSON data
|
||||
|
||||
The following parameters are recognized in callback data:
|
||||
|
||||
* `state` (required): Accepted values are `success`, `failure` and `error`.
|
||||
If the state isn't `success`, the webhook chain will be interrupted.
|
||||
* `description`: A string containing miscellaneous information that will be
|
||||
available on the Docker Hub. Maximum 255 characters.
|
||||
* `context`: A string containing the context of the operation. Can be retrieved
|
||||
from the Docker Hub. Maximum 100 characters.
|
||||
* `target_url`: The URL where the results of the operation can be found. Can be
|
||||
retrieved on the Docker Hub.
|
||||
|
||||
*Example callback payload:*
|
||||
|
||||
{
|
||||
"state": "success",
|
||||
"description": "387 tests PASSED",
|
||||
"context": "Continuous integration by Acme CI",
|
||||
"target_url": "http://ci.acme.com/results/afd339c1c3d27"
|
||||
}
|
||||
|
||||
## Mark as unlisted
|
||||
|
||||
By marking a repository as unlisted, you can create a publicly pullable repository
|
||||
which will not be in the Hub or commandline search. This allows you to have a limited
|
||||
release, but does not restrict access to anyone that is told, or guesses the repository
|
||||
name.

# Using the Docker Hub
|
||||
|
||||
Docker Hub is used to find and pull Docker images to run or build upon, and to
|
||||
distribute and build images for other users to use.
|
||||
|
||||

|
||||
|
||||
## Finding repositories and images
|
||||
|
||||
There are two ways you can search for public repositories and images available
|
||||
on the Docker Hub. You can use the "Search" tool on the Docker Hub website, or
|
||||
you can `search` for all the repositories and images using the Docker commandline
|
||||
tool:
|
||||
|
||||
$ docker search ubuntu
|
||||
|
||||
Both will show you a list of the currently available public repositories on the
|
||||
Docker Hub which match the provided keyword.
|
||||
|
||||
If a repository is private or marked as unlisted, it won't be in the repository
|
||||
search results. To see all the repositories you have access to and their statuses,
|
||||
you can look at your profile page on [Docker Hub](https://hub.docker.com).
|
||||
|
||||
## Pulling, running and building images
|
||||
|
||||
You can find more information on [working with Docker images](../userguide/dockerimages.md).
|
||||
|
||||
## Official Repositories
|
||||
|
||||
The Docker Hub contains a number of [Official
|
||||
Repositories](http://registry.hub.docker.com/official). These are
|
||||
certified repositories from vendors and contributors to Docker. They
|
||||
contain Docker images from vendors like Canonical, Oracle, and Red Hat
|
||||
that you can use to build applications and services.
|
||||
|
||||
If you use Official Repositories you know you're using an optimized and
|
||||
up-to-date image to power your applications.
|
||||
|
||||
> **Note:**
|
||||
> If you would like to contribute an Official Repository for your
|
||||
> organization, see [Official Repositories on Docker
|
||||
> Hub](/docker-hub/official_repos) for more information.
|
||||
|
||||
## Building and shipping your own repositories and images
|
||||
|
||||
The Docker Hub provides you and your team with a place to build and ship Docker images.
|
||||
|
||||
Collections of Docker images are managed using repositories -
|
||||
|
||||
You can configure two types of repositories to manage on the Docker Hub:
|
||||
[Repositories](./repos.md), which allow you to push images to the Hub from your local Docker daemon,
|
||||
and [Automated Builds](./builds.md), which allow you to configure GitHub or Bitbucket to
|
||||
trigger the Hub to rebuild repositories when changes are made to the repository.

**Docker can build images automatically** by reading the instructions
|
||||
from a `Dockerfile`. A `Dockerfile` is a text document that contains all
|
||||
the commands you would normally execute manually in order to build a
|
||||
Docker image. By calling `docker build` from your terminal, you can have
|
||||
Docker build your image step by step, executing the instructions

successively.

||||
Docker can build images automatically by reading the instructions from a
|
||||
`Dockerfile`. A `Dockerfile` is a text document that contains all the commands a
|
||||
user could call on the command line to assemble an image. Using `docker build`
|
||||
users can create an automated build that executes several command-line
|
||||
instructions in succession.
|
||||
|
||||
This page discusses the specifics of all the instructions you can use in your
|
||||
`Dockerfile`. To further help you write a clear, readable, maintainable
|
||||
`Dockerfile`, we've also written a [`Dockerfile` Best Practices
|
||||
guide](/articles/dockerfile_best-practices). Lastly, you can test your
|
||||
Dockerfile knowledge with the [Dockerfile tutorial](/userguide/level1).
|
||||
This page describes the commands you can use in a `Dockerfile`. When you are

done reading this page, refer to the [`Dockerfile` Best

Practices](/articles/dockerfile_best-practices) for a tip-oriented guide.

|
||||
## Usage
|
||||
|
||||
To [*build*](/reference/commandline/cli/#build) an image from a source repository,
|
||||
create a description file called `Dockerfile` at the root of your repository.
|
||||
This file will describe the steps to assemble the image.
|
||||
The [`docker build`](/reference/commandline/build/) command builds an image from
|
||||
a `Dockerfile` and a *context*. The build's context is the files at a specified
|
||||
location `PATH` or `URL`. The `PATH` is a directory on your local filesystem.
|
||||
The `URL` is a the location of a Git repository.
|
||||
|
||||
Then call `docker build` with the path of your source repository as the argument
|
||||
(for example, `.`):
|
||||
A context is processed recursively. So, a `PATH` includes any subdirectories and
|
||||
the `URL` includes the repository and its submodules. A simple build command
|
||||
that uses the current directory as context:
|
||||
|
||||
$ docker build .
|
||||
Sending build context to Docker daemon 6.51 MB
|
||||
...
|
||||
|
||||
The path to the source repository defines where to find the *context* of
|
||||
the build. The build is run by the Docker daemon, not by the CLI, so the
|
||||
whole context must be transferred to the daemon. The Docker CLI reports
|
||||
"Sending build context to Docker daemon" when the context is sent to the daemon.
|
||||
The build is run by the Docker daemon, not by the CLI. The first thing a build
|
||||
process does is send the entire context (recursively) to the daemon. In most
|
||||
cases, it's best to start with an empty directory as context and keep your
|
||||
Dockerfile in that directory. Add only the files needed for building the
|
||||
Dockerfile.
|
||||
|
||||
> **Warning**
|
||||
> Avoid using your root directory, `/`, as the root of the source repository. The
|
||||
> `docker build` command will use whatever directory contains the Dockerfile as the build

|
||||

|
||||
|
||||
In most cases, it's best to put each Dockerfile in an empty directory. Then,
|
||||
only add the files needed for building the Dockerfile to the directory. To
|
||||
increase the build's performance, you can exclude files and directories by
|
||||
adding a `.dockerignore` file to the directory. For information about how to
|
||||
[create a `.dockerignore` file](#dockerignore-file) on this page.
|
||||
To use a file in the build context, the `Dockerfile` refers to the file with
|
||||
an instruction, for example, a `COPY` instruction. To increase the build's
|
||||
performance, exclude files and directories by adding a `.dockerignore` file to
|
||||
the context directory. For information about how to [create a `.dockerignore`

Traditionally, the `Dockerfile` is called `Dockerfile` and located in the root

||||
container's logging driver. The following options are supported:
|
||||
|
||||
| `none` | Disables any logging for the container. `docker logs` won't be available with this driver. |
|
||||
|-------------|-------------------------------------------------------------------------------------------------------------------------------|
|
||||
| `json-file` | Default logging driver for Docker. Writes JSON messages to file. |
|
||||
| `syslog` | Syslog logging driver for Docker. Writes log messages to syslog. |
|
||||
| `journald` | Journald logging driver for Docker. Writes log messages to `journald`. |
|
||||
| `gelf` | Graylog Extended Log Format (GELF) logging driver for Docker. Writes log messages to a GELF endpoint likeGraylog or Logstash. |
|
||||
| `fluentd` | Fluentd logging driver for Docker. Writes log messages to `fluentd` (forward input). |
|
||||
|
||||
The `docker logs`command is available only for the `json-file` logging driver.
|
||||
|
||||
### The json-file options
|
||||
|
||||
The following logging options are supported for the `json-file` logging driver:
|
||||
|
||||
--log-opt max-size=[0-9+][k|m|g]
|
||||
--log-opt max-file=[0-9+]
|
||||
|
||||
Logs that reach `max-size` are rolled over. You can set the size in kilobytes(k), megabytes(m), or gigabytes(g). eg `--log-opt max-size=50m`. If `max-size` is not set, then logs are not rolled over.
|
||||
|
||||
|
||||
`max-file` specifies the maximum number of files that a log is rolled over before being discarded. eg `--log-opt max-file=100`. If `max-size` is not set, then `max-file` is not honored.
|
||||
|
||||
If `max-size` and `max-file` are set, `docker logs` only returns the log lines from the newest log file.
|
||||
|
||||
### The syslog options
|
||||
|
||||
The following logging options are supported for the `syslog` logging driver:
|
||||
|
||||
--log-opt syslog-address=[tcp|udp]://host:port
|
||||
--log-opt syslog-address=unix://path
|
||||
--log-opt syslog-facility=daemon
|
||||
--log-opt syslog-tag="mailer"
|
||||
|
||||
`syslog-address` specifies the remote syslog server address where the driver connects to.
|
||||
If not specified it defaults to the local unix socket of the running system.
|
||||
If transport is either `tcp` or `udp` and `port` is not specified it defaults to `514`
|
||||
The following example shows how to have the `syslog` driver connect to a `syslog`
|
||||
remote server at `192.168.0.42` on port `123`
|
||||
|
||||
$ docker run --log-driver=syslog --log-opt syslog-address=tcp://192.168.0.42:123
|
||||
|
||||
The `syslog-facility` option configures the syslog facility. By default, the system uses the
|
||||
`daemon` value. To override this behavior, you can provide an integer of 0 to 23 or any of
|
||||
the following named facilities:
|
||||
|
||||
* `kern`
|
||||
* `user`
|
||||
* `mail`
|
||||
* `daemon`
|
||||
* `auth`
|
||||
* `syslog`
|
||||
* `lpr`
|
||||
* `news`
|
||||
* `uucp`
|
||||
* `cron`
|
||||
* `authpriv`
|
||||
* `ftp`
|
||||
* `local0`
|
||||
* `local1`
|
||||
* `local2`
|
||||
* `local3`
|
||||
* `local4`
|
||||
* `local5`
|
||||
* `local6`
|
||||
* `local7`
|
||||
|
||||
The `syslog-tag` specifies a tag that identifies the container's syslog messages. By default,
|
||||
the system uses the first 12 characters of the container id. To override this behavior, specify
|
||||
a `syslog-tag` option
|
||||
|
||||
## Specify journald options
|
||||
|
||||
The `journald` logging driver stores the container id in the journal's `CONTAINER_ID` field. For detailed information on
|
||||
working with this logging driver, see [the journald logging driver](/reference/logging/journald/)
|
||||
reference documentation.
|
||||
|
||||
## Specify gelf options
|
||||
|
||||
The GELF logging driver supports the following options:
|
||||
|
||||
--log-opt gelf-address=udp://host:port
|
||||
--log-opt gelf-tag="database"
|
||||
|
||||
The `gelf-address` option specifies the remote GELF server address that the
|
||||
driver connects to. Currently, only `udp` is supported as the transport and you must
|
||||
specify a `port` value. The following example shows how to connect the `gelf`
|
||||
driver to a GELF remote server at `192.168.0.42` on port `12201`
|
||||
|
||||
$ docker run --log-driver=gelf --log-opt gelf-address=udp://192.168.0.42:12201
|
||||
|
||||
The `gelf-tag` option specifies a tag for easy container identification.
|
||||
|
||||
## Specify fluentd options
|
||||
|
||||
You can use the `--log-opt NAME=VALUE` flag to specify these additional Fluentd logging driver options.
|
||||
|
||||
- `fluentd-address`: specify `host:port` to connect [localhost:24224]
|
||||
- `fluentd-tag`: specify tag for `fluentd` message,
|
||||
|
||||
When specifying a `fluentd-tag` value, you can use the following markup tags:
|
||||
|
||||
- `{{.ID}}`: short container id (12 characters)
|
||||
- `{{.FullID}}`: full container id
|
||||
- `{{.Name}}`: container name
|
||||
|
||||
For example, to specify both additional options:
|
||||
|
||||
`docker run --log-driver=fluentd --log-opt fluentd-address=localhost:24224 --log-opt fluentd-tag=docker.{{.Name}}`
|
||||
|
||||
If container cannot connect to the Fluentd daemon on the specified address,
|
||||
the container stops immediately. For detailed information on working with this
|
||||
logging driver, see [the fluentd logging driver](/reference/logging/fluentd/)

# Configure logging drivers
|
||||
|
||||
The container can have a different logging driver than the Docker daemon. Use
|
||||
the `--log-driver=VALUE` with the `docker run` command to configure the
|
||||
container's logging driver. The following options are supported:
|
||||
|
||||
| `none` | Disables any logging for the container. `docker logs` won't be available with this driver. |

--log-opt syslog-facility=daemon
|
||||
--log-opt syslog-tag="mailer"
|

`syslog-address` specifies the remote syslog server address where the driver connects to.
|
||||
If not specified it defaults to the local unix socket of the running system.
|
||||
If transport is either `tcp` or `udp` and `port` is not specified it defaults to `514`
|

# Container
|
||||
|
||||
## Introduction
|
||||
|
||||

|
||||
|
||||
Once you start a process in Docker from an [*Image*](/terms/image), Docker
|
||||
fetches the image and its [*Parent Image*](/terms/image), and repeats the
|
||||
process until it reaches the [*Base Image*](/terms/image/#base-image-def). Then
|
||||
the [*Union File System*](/terms/layer) adds a read-write layer on top. That
|
||||
read-write layer, plus the information about its [*Parent
|
||||
Image*](/terms/image)
|
||||
and some additional information like its unique id, networking
|
||||
configuration, and resource limits is called a **container**.
|
||||
|
||||
## Container state
|
||||
|
||||
Containers can change, and so they have state. A container may be
|
||||
**running** or **exited**.
|
||||
|
||||
When a container is running, the idea of a "container" also includes a
|
||||
tree of processes running on the CPU, isolated from the other processes
|
||||
running on the host.
|
||||
|
||||
When the container is exited, the state of the file system and its exit
|
||||
value is preserved. You can start, stop, and restart a container. The
|
||||
processes restart from scratch (their memory state is **not** preserved
|
||||
in a container), but the file system is just as it was when the
|
||||
container was stopped.
|
||||
|
||||
You can promote a container to an [*Image*](/terms/image) with `docker commit`.
|
||||
Once a container is an image, you can use it as a parent for new containers.
|
||||
|
||||
## Container IDs
|
||||
|
||||
All containers are identified by a 64 hexadecimal digit string
|
||||
(internally a 256bit value). To simplify their use, a short ID of the
|
||||
first 12 characters can be used on the command line. There is a small
|
||||
possibility of short id collisions, so the docker server will always
|
||||
return the long ID.

# File system
|
||||
|
||||
## Introduction
|
||||
|
||||

|
||||
|
||||
In order for a Linux system to run, it typically needs two [file
|
||||
systems](http://en.wikipedia.org/wiki/Filesystem):
|
||||
|
||||
1. boot file system (bootfs)
|
||||
2. root file system (rootfs)
|
||||
|
||||
The **boot file system** contains the bootloader and the kernel. The
|
||||
user never makes any changes to the boot file system. In fact, soon
|
||||
after the boot process is complete, the entire kernel is in memory, and
|
||||
the boot file system is unmounted to free up the RAM associated with the
|
||||
initrd disk image.
|
||||
|
||||
The **root file system** includes the typical directory structure we
|
||||
associate with Unix-like operating systems:
|
||||
`/dev, /proc, /bin, /etc, /lib, /usr,` and `/tmp` plus all the configuration
|
||||
files, binaries and libraries required to run user applications (like bash,
|
||||
ls, and so forth).
|
||||
|
||||
While there can be important kernel differences between different Linux
|
||||
distributions, the contents and organization of the root file system are
|
||||
usually what make your software packages dependent on one distribution
|
||||
versus another. Docker can help solve this problem by running multiple
|
||||
distributions at the same time.

# Image
|
||||
|
||||
## Introduction
|
||||
|
||||

|
||||
|
||||
In Docker terminology, a read-only [*Layer*](/terms/layer/#layer) is
|
||||
called an **image**. An image never changes.
|
||||
|
||||
Since Docker uses a [*Union File System*](/terms/layer/#union-file-system), the
|
||||
processes think the whole file system is mounted read-write. But all the
|
||||
changes go to the top-most writeable layer, and underneath, the original
|
||||
file in the read-only image is unchanged. Since images don't change,
|
||||
images do not have state.
|
||||
|
||||

|
||||
|
||||
## Parent image
|
||||
|
||||

|
||||
|
||||
Each image may depend on one more image which forms the layer beneath
|
||||
it. We sometimes say that the lower image is the **parent** of the upper
|
||||
image.
|
||||
|
||||
## Base image
|
||||
|
||||
An image that has no parent is a **base image**.
|
||||
|
||||
## Image IDs
|
||||
|
||||
All images are identified by a 64 hexadecimal digit string (internally a
|
||||
256bit value). To simplify their use, a short ID of the first 12
|
||||
characters can be used on the command line. There is a small possibility

||||
of short id collisions, so the docker server will always return the long

||||
ID.

# Layers
|
||||
|
||||
## Introduction
|
||||
|
||||
In a traditional Linux boot, the kernel first mounts the root [*File
|
||||
System*](/terms/filesystem) as read-only, checks its
|
||||
integrity, and then switches the whole rootfs volume to read-write mode.
|
||||
|
||||
## Layer
|
||||
|
||||
When Docker mounts the rootfs, it starts read-only, as in a traditional
|
||||
Linux boot, but then, instead of changing the file system to read-write
|
||||
mode, it takes advantage of a [union
|
||||
mount](http://en.wikipedia.org/wiki/Union_mount) to add a read-write
|
||||
file system *over* the read-only file system. In fact there may be
|
||||
multiple read-only file systems stacked on top of each other. We think
|
||||
of each one of these file systems as a **layer**.
|
||||
|
||||

|
||||
|
||||
At first, the top read-write layer has nothing in it, but any time a
|
||||
process creates a file, this happens in the top layer. And if something
|
||||
needs to update an existing file in a lower layer, then the file gets
|
||||
copied to the upper layer and changes go into the copy. The version of
|
||||
the file on the lower layer cannot be seen by the applications anymore,
|
||||
but it is there, unchanged.
|
||||
|
||||
## Union File System
|
||||
|
||||
We call the union of the read-write layer and all the read-only layers a
|
||||
**union file system**.

# Repository
|
||||
|
||||
## Introduction
|
||||
|
||||
A repository is a set of images either on your local Docker server, or
|
||||
shared, by pushing it to a [*Registry*](/terms/registry/#registry-def)
|
||||
server.
|
||||
|
||||
Images can be associated with a repository (or multiple) by giving them
|
||||
an image name using one of three different commands:
|
||||
|
||||
1. At build time (e.g., `docker build -t IMAGENAME`),
|
||||
2. When committing a container (e.g.,
|
||||
`docker commit CONTAINERID IMAGENAME`) or
|
||||
3. When tagging an image id with an image name (e.g.,
|
||||
`docker tag IMAGEID IMAGENAME`).
|
||||
|
||||
A Fully Qualified Image Name (FQIN) can be made up of 3 parts:
|
||||
|
||||
`[registry_hostname[:port]/][user_name/](repository_name:version_tag)`
|
||||
|
||||
`username` and `registry_hostname` default to an empty string. When
|
||||
`registry_hostname` is an empty string, then `docker push` will push to
|
||||
`index.docker.io:80`.
|
||||
|
||||
If you create a new repository which you want to share, you will need to
|
||||
set at least the `user_name`, as the `default` blank `user_name` prefix is
|
||||
reserved for [Official Repositories](/docker-hub/official_repos).

# Getting started with Docker Hub
|
||||
|
||||
|
||||
This section provides a quick introduction to the [Docker Hub](https://hub.docker.com),
|
||||
including how to create an account.
|
||||
|
||||
The [Docker Hub](https://hub.docker.com) is a centralized resource for working with
|
||||
Docker and its components. Docker Hub helps you collaborate with colleagues and get the
|
||||
most out of Docker. To do this, it provides services such as:
|
||||
|
||||
* Docker image hosting.
|
||||
* User authentication.
|
||||
* Automated image builds and work-flow tools such as build triggers and web
|
||||
hooks.
|
||||
* Integration with GitHub and Bitbucket.
|
||||
|
||||
In order to use Docker Hub, you will first need to register and create an account. Don't
|
||||
worry, creating an account is simple and free.
|
||||
|
||||
## Creating a Docker Hub account
|
||||
|
||||
There are two ways for you to register and create an account:
|
||||
|
||||
1. Via the web, or
|
||||
2. Via the command line.
|
||||
|
||||
### Register via the web
|
||||
|
||||
Fill in the [sign-up form](https://hub.docker.com/account/signup/) by
|
||||
choosing your user name and password and entering a valid email address. You can also
|
||||
sign up for the Docker Weekly mailing list, which has lots of information about what's
|
||||
going on in the world of Docker.
|
||||
|
||||

|
||||
|
||||
### Register via the command line
|
||||
|
||||
You can also create a Docker Hub account via the command line with the
|
||||
`docker login` command.
|
||||
|
||||
$ docker login
|
||||
|
||||
### Confirm your email
|
||||
|
||||
Once you've filled in the form, check your email for a welcome message asking for
|
||||
confirmation so we can activate your account.
|
||||
|
||||
|
||||
### Login
|
||||
|
||||
After you complete the confirmation process, you can login using the web console:
|
||||
|
||||

|
||||
|
||||
Or via the command line with the `docker login` command:
|
||||
|
||||
$ docker login
|
||||
|
||||
Your Docker Hub account is now active and ready to use.
