Derek McGowan 87f59e3802 Skip V2 registry and immediately fallback to V1 when mirrors are provided
Since V2 registry does not yet implement mirrors, when mirrors are given automatically fallback to V1 without checking V2 first.

Thomas Orozco 967f80f3cc Fix: Failed Start breaks VolumesFrom
Running parseVolumesFromSpec on all VolumesFrom specs before initialize
any mounts endures that we don't leave container.Volumes in an
inconsistent (partially initialized) if one of out mount groups is not
available (e.g. the container we're trying to mount from does not
exist).

Keeping container.Volumes in a consistent state ensures that next time
we Start() the container, it'll run prepareVolumes() again.

The attached test demonstrates that when a container fails to start due
to a missing container specified in VolumesFrom, it "remembers" a Volume
that worked.

Fixes: #8726

Josh Hawn 3ab5251f56 Use archive.CopyWithTar in vfs.Create
The vfs storage driver currently shells out to the `cp` binary on the host
system to perform an 'archive' copy of the base image to a new directory.
The archive option preserves the modified time of the files which are created
but there was an issue where it was unable to preserve the modified time of
copied symbolic links on some host systems with an outdated version of `cp`.

This change no longer relies on the host system implementation and instead
utilizes the `CopyWithTar` function found in `pkg/archive` which is used
to copy from source to destination directory using a Tar archive, which
should correctly preserve file attributes.

Michael Crosby c9379eb3fb Move security opts to HostConfig
These settings need to be in the HostConfig so that they are not
committed to an image and cannot introduce a security issue.

We can safely move this field from the Config to the HostConfig
without any regressions because these settings are consumed at container
created and used to populate fields on the Container struct.  Because of
this, existing settings will be honored for containers already created
on a daemon with custom security settings and prevent values being
consumed via an Image.

## Release Notes
**Version 1.3.0**
This version fixes a number of bugs and issues and adds new functions and other
improvements. These include:
*New command: `docker exec`*
The new `docker exec` command lets you run a process in an existing, active
container. The command has APIs for both the daemon and the client. With
`docker exec`, you'll be able to do things like add or remove devices from running containers, debug running containers, and run commands that are not
part of the container's static specification.
*New command: `docker create`*
Traditionally, the `docker run` command has been used to both create a
container and spawn a process to run it. The new `docker create` command breaks
this apart, letting you set up a container without actually starting it. This
provides more control over management of the container lifecycle, giving you the
ability to configure things like volumes or port mappings before the container
is started. For example, in a rapid-response scaling situation, you could use
`create` to prepare and stage ten containers in anticipation of heavy loads.
*New provenance features*
Official images are now signed by Docker, Inc. to improve your confidence and
security. Look for the blue ribbons on the [Docker Hub](https://hub.docker.com/).
The Docker Engine has been updated to automatically verify that a given Official
Repo has a current, valid signature. If no valid signature is detected, Docker
Engine will use a prior image.
*Other improvements & changes*
We've added a new security options flag that lets you set SELinux and AppArmor
labels and profiles. This means you'll longer have to use `docker run
--privileged on kernels that support SE Linux or AppArmor.
A summary of the changes in each release in the current series can now be found on the separate [Release Notes page](/release-notes/)

### Insecure registries
Docker considers a private registry either secure or insecure.
In the rest of this section, *registry* is used for *private registry*, and `myregistry:5000`
is a placeholder example for a private registry.
A secure registry uses TLS and a copy of its CA certificate is placed on the Docker host at
`/etc/docker/certs.d/myregistry:5000/ca.crt`.
An insecure registry is either not using TLS (i.e., listening on plain text HTTP), or is using
TLS with a CA certificate not known by the Docker daemon. The latter can happen when the
certificate was not found under `/etc/docker/certs.d/myregistry:5000/`, or if the certificate
verification failed (i.e., wrong CA).
By default, Docker assumes all, but local (see local registries below), registries are secure.
Communicating with an insecure registry is not possible if Docker assumes that registry is secure.
In order to communicate with an insecure registry, the Docker daemon requires `--insecure-registry`
in one of the following two forms:
* `--insecure-registry myregistry:5000` tells the Docker daemon that myregistry:5000 should be considered insecure.
* `--insecure-registry 10.1.0.0/16` tells the Docker daemon that all registries whose domain resolve to an IP address is part
of the subnet described by the CIDR syntax, should be considered insecure.
The flag can be used multiple times to allow multiple registries to be marked as insecure.
If an insecure registry is not marked as insecure, `docker pull`, `docker push`, and `docker search`
will result in an error message prompting the user to either secure or pass the `--insecure-registry`
flag to the Docker daemon as described above.
Local registries, whose IP address falls in the 127.0.0.0/8 range, are automatically marked as insecure
as of Docker 1.3.2. It is not recommended to rely on this, as it may change in the future.
### Miscellaneous options
IP masquerading uses address translation to allow containers without a public IP to talk
to other machines on the Internet. This may interfere with some network topologies and
can be disabled with --ip-masq=false.
Docker supports softlinks for the Docker data directory
(`/var/lib/docker`) and for `/var/lib/docker/tmp`. The `DOCKER_TMPDIR` and the data directory can be set like this:

#Release Notes
##Version 1.3.2
(2014-11-24)
This release fixes some bugs and addresses some security issues. We have also
made improvements to aspects of `docker run`.
*Security fixes*
Patches and changes were made to address CVE-2014-6407 and CVE-2014-6408.
Specifically, changes were made in order to:
* Prevent host privilege escalation from an image extraction vulnerability (CVE-2014-6407).
* Prevent container escalation from malicious security options applied to images (CVE-2014-6408).
*Daemon fixes*
The `--insecure-registry` flag of the `docker run` command has undergone
several refinements and additions. For details, please see the
[command-line reference](http://docs.docker.com/reference/commandline/cli/#run).
* You can now specify a sub-net in order to set a range of registries which the Docker daemon will consider insecure.
* By default, Docker now defines `localhost` as an insecure registry.
* Registries can now be referenced using the Classless Inter-Domain Routing (CIDR) format.
* When mirroring is enabled, the experimental registry v2 API is skipped.
##Version 1.3.1
(2014-10-28)
This release fixes some bugs and addresses some security issues.
*Security fixes*
Patches and changes were made to address CVE-2014-5277 and CVE-2014-3566. Specifically, changes were made to:
* Prevent fallback to SSL protocols < TLS 1.0 for client, daemon and registry
* Secure HTTPS connection to registries with certificate verification and without HTTP fallback unless `--insecure-registry` is specified.
*Runtime fixes*
* Fixed issue where volumes would not be shared
*Client fixes*
* Fixed issue with `--iptables=false` not automatically setting
`--ip-masq=false`
* Fixed docker run output to non-TTY stdout
*Builder fixes*
* Fixed escaping `$` for environment variables
* Fixed issue with lowercase `onbuild` Dockerfile instruction
##Version 1.3.0
This version fixes a number of bugs and issues and adds new functions and other
improvements. The [GitHub 1.3milestone](https://github.com/docker/docker/issues?q=milestone%3A1.3.0+) has
more detailed information. Major additions and changes include:
###New Features
*New command: `docker exec`*
The new `docker exec` command lets you run a process in an existing, active
container. The command has APIs for both the daemon and the client. With `docker
exec`, you'll be able to do things like add or remove devices from running
containers, debug running containers, and run commands that are not part of the
container's static specification. Details in the [command line reference](/reference/commandline/cli/#exec).
*New command: `docker create`*
Traditionally, the `docker run` command has been used to both create a container
and spawn a process to run it. The new `docker create` command breaks this
apart, letting you set up a container without actually starting it. This
provides more control over management of the container lifecycle, giving you the
ability to configure things like volumes or port mappings before the container
is started. For example, in a rapid-response scaling situation, you could use
`create` to prepare and stage ten containers in anticipation of heavy loads.
Details in the [command line reference](/reference/commandline/cli/#create).
*Tech preview of new provenance features*
This release offers a sneak peek at new image signing capabilities that are
currently under development. Soon, these capabilities will allow any image
author to sign their images to certify they have not been tampered with. For
this release, Official images are now signed by Docker, Inc. Not only does this
demonstrate the new functionality, we hope it will improve your confidence in
the security of Official images. Look for the blue ribbons denoting signed
images on the [Docker Hub](https://hub.docker.com/). The Docker Engine has been
updated to automatically verify that a given Official Repo has a current, valid
signature. When pulling a signed image, you'll see a message stating `the image
you are pulling has been verified`. If no valid signature is detected, Docker
Engine will fall back to pulling a regular, unsigned image.
###Other improvements & changes*
* We've added a new security options flag to the `docker run` command,
`--security-opt`, that lets you set SELinux and AppArmor labels and profiles.
This means you'll no longer have to use `docker run --privileged` on kernels
that support SE Linux or AppArmor. For more information, see the [command line
reference](/reference/commandline/cli/#run).
* A new flag, `--add-host`, has been added to `docker run` that lets you add
lines to `/etc/hosts`. This allows you to specify different name resolution for
the container than it would get via DNS. For more information, see the [command
line reference](/reference/commandline/cli/#run).
* You can now set a `DOCKER_TLS_VERIFY` environment variable to secure
connections by default (rather than having to pass the `--tlsverify` flag on
every call). For more information, see the [https guide](/articles/https).
* Three security issues have been addressed in this release: [CVE-2014-5280,
CVE-2014-5270, and
CVE-2014-5282](https://groups.google.com/forum/#!msg/docker-announce/aQoVmQlcE0A/smPuBNYf8VwJ).
##Version 1.2.0
This version fixes a number of bugs and issues and adds new functions and other
improvements. These include:
###New Features
*New restart policies*
We added a `--restart flag` to `docker run` to specify a restart policy for your
container. Currently, there are three policies available:
* `no` Do not restart the container if it dies. (default) * `on-failure`
Restart the container if it exits with a non-zero exit code. This can also
accept an optional maximum restart count (e.g. `on-failure:5`). * `always`
Always restart the container no matter what exit code is returned. This
deprecates the `--restart` flag on the Docker daemon.
*New flags for `docker run`: `--cap-add` and `-cap-drop`*
In previous releases, Docker containers could either be given complete
capabilities or they could all follow a whitelist of allowed capabilities while
dropping all others. Further, using `--privileged` would grant all capabilities
inside a container, rather than applying a whitelist. This was not recommended
for production use because its really unsafe; its as if you were directly in
the host.
This release introduces two new flags for `docker run`, `--cap-add` and
`--cap-drop`, that give you fine-grain control over the specific capabilities
you want grant to a particular container.
*New `-device` flag for `docker run`*
Previously, you could only use devices inside your containers by bind mounting
them (with `-v`) in a `--privileged` container. With this release, we introduce
the `--device flag` to `docker run` which lets you use a device without
requiring a privileged container.
*Writable `/etc/hosts`, `/etc/hostname` and `/etc/resolv.conf`*
You can now edit `/etc/hosts`, `/etc/hostname` and `/etc/resolve.conf` in a
running container. This is useful if you need to install BIND or other services
that might override one of those files.
Note, however, that changes to these files are not saved when running `docker
build` and so will not be preserved in the resulting image. The changes will
only “stick” in a running container.
*Docker proxy in a separate process*
The Docker userland proxy that routes outbound traffic to your containers now
has its own separate process (one process per connection). This greatly reduces
the load on the daemon, which increases stability and efficiency.
###Other improvements & changes
* When using `docker rm -f`, Docker now kills the container (instead of stopping
it) before removing it . If you intend to stop the container cleanly, you can
use `docker stop`.
* Added support for IPv6 addresses in `--dns`
* Added search capability in private registries
##Version 1.1.0
###New Features
*`.dockerignore` support*
You can now add a `.dockerignore` file next to your `Dockerfile` and Docker will
ignore files and directories specified in that file when sending the build
context to the daemon. Example:
https://github.com/docker/docker/blob/master/.dockerignore
*Pause containers during commit*
Doing a commit on a running container was not recommended because you could end
up with files in an inconsistent state (for example, if they were being written
during the commit). Containers are now paused when a commit is made to them. You
can disable this feature by doing a `docker commit --pause=false <container_id>`
*Tailing logs*
You can now tail the logs of a container. For example, you can get the last ten
lines of a log by using `docker logs --tail 10 <container_id>`. You can also
follow the logs of a container without having to read the whole log file with
`docker logs --tail 0 -f <container_id>`.
*Allow a tar file as context for docker build*
You can now pass a tar archive to `docker build` as context. This can be used to
automate docker builds, for example: `cat context.tar | docker build -` or
`docker run builder_image | docker build -`
*Bind mounting your whole filesystem in a container*
`/` is now allowed as source of `--volumes`. This means you can bind-mount your
whole system in a container if you need to. For example: `docker run -v
/:/my_host ubuntu:ro ls /my_host`. However, it is now forbidden to mount to /.
###Other Improvements & Changes
* Port allocation has been improved. In the previous release, Docker could
prevent you from starting a container with previously allocated ports which
seemed to be in use when in fact they were not. This has been fixed.
* A bug in `docker save` was introduced in the last release. The `docker save`
command could produce images with invalid metadata. The command now produces
images with correct metadata.
* Running `docker inspect` in a container now returns which containers it is
linked to.
* Parsing of the `docker commit` flag has improved validation, to better prevent
you from committing an image with a name such as `-m`. Image names with dashes
in them potentially conflict with command line flags.
* The API now has Improved status codes for `start` and `stop`. Trying to start
a running container will now return a 304 error.
* Performance has been improved overall. Starting the daemon is faster than in
previous releases. The daemons performance has also been improved when it is
working with large numbers of images and containers.
* Fixed an issue with white-spaces and multi-lines in Dockerfiles.
##Version 1.1.0
###New Features
*`.dockerignore` support*
You can now add a `.dockerignore` file next to your `Dockerfile` and Docker will
ignore files and directories specified in that file when sending the build
context to the daemon. Example:
https://github.com/dotcloud/docker/blob/master/.dockerignore
*Pause containers during commit*
Doing a commit on a running container was not recommended because you could end
up with files in an inconsistent state (for example, if they were being written
during the commit). Containers are now paused when a commit is made to them. You
