Michael Crosby 1db7cb2f01 Updated fixes post rebase from master
Removed test cases that are no longer
applicable with links and the port changes.
Remove test case where a test was hitting an
external ip.
2013-10-18 14:05:53 -07:00
Alexander Larsson e6e6d89cc1 Move SysInit to a submodule
This allows docker-init to not import the main docker
module, which means it won't e.g. pick up any sqlite
dependencies.
2013-10-18 14:05:53 -07:00
Alexander Larsson 1484434196 Move ListOps to utils submodule
This will be needed for later use in docker-init without a docker
dependency
2013-10-18 14:05:53 -07:00
Alexander Larsson 34c7fb0c43 Add a network test
This just tries pinging first 127.0.0.1 and then 8.8.8.8.

We can't ping via a dns name, because libresolv.so is missing
from the test image, so dns resolving doesn't work.
2013-10-18 14:05:53 -07:00
Alexander Larsson 9268e5e42f network: Stop shelling out to /sbin/ip
We have our own netlink version of all the required calls now, so
we can just skip the /sbin/ip dependency.
2013-10-18 14:05:53 -07:00
Alexander Larsson 04f8ffa140 Use netlink directly instead of /bin/ip in Sysinit
The sysinit code only uses /bin/ip to set a default gateway. This
is pretty easy to do via netlink directly, so we can avoid
the ip dependency.
2013-10-18 14:05:53 -07:00
Alexander Larsson 7e3e662ba5 Add netlink submodule
This contains various operations that can replace the use of
shelling out to "ip".
2013-10-18 14:05:52 -07:00
Michael Crosby 2b17d79e5b Add flag for inter-container communication 2013-10-18 14:05:52 -07:00

What does that mean?
Here is a further explanation from our legal counsel:
For more information, please see http://www.bis.doc.gov
Like all software products that utilize cryptography, the export and
use of Docker is subject to the U.S. Commerce Department's Export
Administration Regulations (EAR) because it uses or contains
cryptography (see
http://www.bis.doc.gov/index.php/policy-guidance/encryption). Certain
free and open source software projects have a lightweight set of
requirements, which can generally be met by providing email notice to
the appropriate U.S. government agencies that their source code is
available on a publicly available repository and making the
appropriate statements in the README.
See also http://www.apache.org/dev/crypto.html and/or seek legal counsel.
The restrictions of the EAR apply to certain denied locations
(currently Iran, Sudan, Syria, North Korea, or Cuba) and those
individuals on the Denied Persons List, which is available here:
http://www.bis.doc.gov/index.php/policy-guidance/lists-of-parties-of-concern/denied-persons-list.
If you are incorporating Docker into a new open source project, the
EAR restrictions apply to your incorporation of Docker into your
project in the same manner as other cryptography-enabled projects,
such as OpenSSL, almost all Linux distributions, etc.
For more information, see http://www.apache.org/dev/crypto.html and/or
seek legal counsel.

# only script to run before the other script, you have to jump through a lot of
# hoops.
#
# Here is my only repeatable solution: make one script that is common ($script)

# docker-brew
docker-brew is a command-line tool used to build the docker standard library.
## Install instructions
1. Install python if it isn't already available on your OS of choice
1. Install the easy_install tool (`sudo apt-get install python-setuptools`
for Debian)
1. Install the python package manager, `pip` (`easy_install pip`)
1. Run the following command: `sudo pip install -r requirements.txt`
1. You should now be able to use the `docker-brew` script as such.
## Basics
./docker-brew -h
Display usage and help.
./docker-brew
Default build from the default repo/branch. Images will be created under the
`library/` namespace. Does not perform a remote push.
./docker-brew -n mycorp.com -b stable --push git://github.com/mycorp/docker
Will fetch the library definition files in the `stable` branch of the
`git://github.com/mycorp/docker` repository and create images under the
`mycorp.com` namespace (e.g. `mycorp.com/ubuntu`). Created images will then
be pushed to the official docker repository (pending: support for private
repositories)
## Library definition files
The library definition files are plain text files found in the `library/`
subfolder of the docker repository.
### File names
The name of a definition file will determine the name of the image(s) it
creates. For example, the `library/ubuntu` file will create images in the
`<namespace>/ubuntu` repository. If multiple instructions are present in
a single file, all images are expected to be created under a different tag.
### Instruction format
Each line represents a build instruction.
There are different formats that `docker-brew` is able to parse.
<git-url>
git://github.com/dotcloud/hipache
https://github.com/dotcloud/docker.git
The simplest format. `docker-brew` will fetch data from the provided git
repository from the `HEAD`of its `master` branch. Generated image will be
tagged as `latest`. Use of this format is discouraged because there is no
way to ensure stability.
<docker-tag> <git-url>
bleeding-edge git://github.com/dotcloud/docker
unstable https://github.com/dotcloud/docker-redis.git
A more advanced format. `docker-brew` will fetch data from the provided git
repository from the `HEAD`of its `master` branch. Generated image will be
tagged as `<docker-tag>`. Recommended if we always want to provide a snapshot
of the latest development. Again, no way to ensure stability.
<docker-tag> <git-url> T:<git-tag>
2.4.0 git://github.com/dotcloud/docker-redis T:2.4.0
<docker-tag> <git-url> B:<git-branch>
zfs git://github.com/dotcloud/docker B:zfs-support
<docker-tag> <git-url> C:<git-commit-id>
2.2.0 https://github.com/dotcloud/docker-redis.git C:a4bf8923ee4ec566d3ddc212
The most complete format. `docker-brew` will fetch data from the provided git
repository from the provided reference (if it's a branch, brew will fetch its
`HEAD`). Generated image will be tagged as `<docker-tag>`. Recommended whenever
possible.

# DESCRIPTION: Create data image sharing /data volume
# AUTHOR: Daniel Mizyrycki <daniel@dotcloud.com>
# COMMENTS:
# This image is used as base for all data containers.
# /data volume is owned by sysadmin.
# USAGE:
# # Download data Dockerfile
# wget http://raw.github.com/dotcloud/docker/master/contrib/desktop-integration/data/Dockerfile
#
# # Build data image
# docker build -t data -rm .
#
# # Create a data container. (eg: firefox-data)
# docker run -name firefox-data data true
#
# # List data from it
# docker run -volumes-from firefox-data busybox ls -al /data
docker-version 0.6.5
# Smallest base image, just to launch a container
from busybox
maintainer Daniel Mizyrycki <daniel@docker.com>
# Create a regular user
run echo 'sysadmin:x:1000:1000::/data:/bin/sh' >> /etc/passwd
run echo 'sysadmin:x:1000:' >> /etc/group
# Create directory for that user
run mkdir /data
run chown sysadmin.sysadmin /data
# Add content to /data. This will keep sysadmin ownership
run touch /data/init_volume

# DESCRIPTION: Create firefox container with its dependencies
# AUTHOR: Daniel Mizyrycki <daniel@dotcloud.com>
# COMMENTS:
# This file describes how to build a Firefox container with all
# dependencies installed. It uses native X11 unix socket and alsa
# sound devices. Tested on Debian 7.2
# USAGE:
# # Download Firefox Dockerfile
# wget http://raw.github.com/dotcloud/docker/master/contrib/desktop-integration/firefox/Dockerfile
#
# # Build firefox image
# docker build -t firefox -rm .
#
# # Run stateful data-on-host firefox. For ephemeral, remove -v /data/firefox:/data
# docker run -v /data/firefox:/data -v /tmp/.X11-unix:/tmp/.X11-unix \
# -v /dev/snd:/dev/snd -lxc-conf='lxc.cgroup.devices.allow = c 116:* rwm' \
# -e DISPLAY=unix$DISPLAY firefox
#
# # To run stateful dockerized data containers
# docker run -volumes-from firefox-data -v /tmp/.X11-unix:/tmp/.X11-unix \
# -v /dev/snd:/dev/snd -lxc-conf='lxc.cgroup.devices.allow = c 116:* rwm' \
# -e DISPLAY=unix$DISPLAY firefox
docker-version 0.6.5
# Base docker image

# Vagrant integration
# Vagrant-docker
Currently there are at least 4 different projects that we are aware of that deals
with integration with [Vagrant](http://vagrantup.com/) at different levels. One
approach is to use Docker as a [provisioner](http://docs.vagrantup.com/v2/provisioning/index.html)
which means you can create containers and pull base images on VMs using Docker's
CLI and the other is to use Docker as a [provider](http://docs.vagrantup.com/v2/providers/index.html),
meaning you can use Vagrant to control Docker containers.
### Provisioners
* [Vocker](https://github.com/fgrehm/vocker)
* [Ventriloquist](https://github.com/fgrehm/ventriloquist)
### Providers
* [docker-provider](https://github.com/fgrehm/docker-provider)
* [vagrant-shell](https://github.com/destructuring/vagrant-shell)
This is a placeholder for the official vagrant-docker, a plugin for Vagrant (http://vagrantup.com) which exposes Docker as a provider.

Linking Redis
=============
.. include:: example_header.inc
Building a redis container to link as a child of our web application.
Building the redis container
----------------------------
We will use a pre-build version of redis from the index under
the name ``crosbymichael/redis``. If you are interested in the
Dockerfile that was used to build this container here it is.
.. code-block:: bash
# Build redis from source
# Make sure you have the redis source code checked out in
# the same directory as this Dockerfile
FROM ubuntu
RUN echo "deb http://archive.ubuntu.com/ubuntu precise main universe" > /etc/apt/sources.list
RUN apt-get update
RUN apt-get upgrade -y
RUN apt-get install -y gcc make g++ build-essential libc6-dev tcl
ADD . /redis
RUN (cd /redis && make)
RUN (cd /redis && make test)
RUN mkdir -p /redis-data
VOLUME ["/redis-data"]
EXPOSE 6379
ENTRYPOINT ["/redis/src/redis-server"]
CMD ["--dir", "/redis-data"]
We need to ``EXPOSE`` the default port of 6379 so that our link knows what ports
to connect to our redis container on. If you do not expose any ports for the
image then docker will not be able to establish the link between containers.
Run the redis container
-----------------------
.. code-block:: bash
docker run -d -e PASSWORD=docker crosbymichael/redis --requirepass docker
This will run our redis container using the default port of 6379 and using
as password to secure our service. Next we will link the redis container to
a new name using ``docker link``.
Linking an existing container
-----------------------------
Docker will automatically create an initial link with the container's id but
because the is long and not very user friendly we can link the container with
a new name.
.. code-block:: bash
docker link /39588b6a45100ef5b328b2c302ea085624f29e6cbab70f88be04793af02cec89 /redis
Now we can reference our running redis service using the friendly name ``/redis``.
We can issue all the commands that you would expect; start, stop, attach, using the new name.
Linking redis as a child
------------------------
Next we can start a new web application that has a dependency on redis and apply a link
to connect both containers. If you noticed when running our redis service we did not use
the ``-p`` option to publish the redis port to the host system. Redis exposed port 6379
but we did not publish the port. This allows docker to prevent all network traffic to
the redis container except when explicitly specified within a link. This is a big win
for security.
Now lets start our web application with a link into redis.
.. code-block:: bash
docker run -t -i -link /redis:db ubuntu bash
root@4c01db0b339c:/# env
HOSTNAME=4c01db0b339c
DB_NAME=/4c01db0b339cf19958731255a796ee072040a652f51652a4ade190ab8c27006f/db
TERM=xterm
DB_PORT=tcp://172.17.0.8:6379
DB_PORT_6379_TCP=tcp://172.17.0.8:6379
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
PWD=/
DB_ENV_PASSWORD=dockerpass
SHLVL=1
HOME=/
container=lxc
_=/usr/bin/env
root@4c01db0b339c:/#
When we inspect the environment of the linked container we can see a few extra environment
variables have been added. When you specified ``-link /redis:db`` you are telling docker
to link the container named ``/redis`` into this new container with the alias ``db``.
Environment variables are prefixed with the alias so that the parent container can access
network and environment information from the child.
.. code-block:: bash
# The name of the child container
DB_NAME=/4c01db0b339cf19958731255a796ee072040a652f51652a4ade190ab8c27006f/db
# The default protocol, ip, and port of the service running in the container
DB_PORT=tcp://172.17.0.8:6379
# A specific protocol, ip, and port of various services
DB_PORT_6379_TCP=tcp://172.17.0.8:6379
# Get environment variables of the container
DB_ENV_PASSWORD=dockerpass
Accessing the network information along with the environment of the child container allows
us to easily connect to the redis service on the specific ip and port and use the password
specified in the environment.

.. include:: example_header.inc
Very simple, no frills, Redis service attached to a web application using a link.
Very simple, no frills, redis service.
Create a docker container for Redis
-----------------------------------
Firstly, we create a ``Dockerfile`` for our new Redis image.
Open a docker container
-----------------------
.. code-block:: bash
FROM ubuntu:12.10
RUN apt-get update
RUN apt-get -y install redis-server
EXPOSE 6379
ENTRYPOINT ["/usr/bin/redis-server"]
sudo docker run -i -t ubuntu /bin/bash
Next we build an image from our ``Dockerfile``. Replace ``<your username>``
with your own user name.
Building your image
-------------------
.. code-block:: bash
sudo docker build -t <your username>/redis
Run the service
---------------
Use the image we've just created and name your container ``redis``.
Running the service with ``-d`` runs the container in detached mode, leaving the
container running in the background.
Importantly, we're not exposing any ports on our container. Instead we're going to
use a container link to provide access to our Redis database.
.. code-block:: bash
sudo docker run -name redis -d <your username>/redis
Create your web application container
-------------------------------------
Next we can create a container for our application. We're going to use the ``-link``
flag to create a link to the ``redis`` container we've just created with an alias of
``db``. This will create a secure tunnel to the ``redis`` container and expose the
Redis instance running inside that container to only this container.
.. code-block:: bash
sudo docker run -link redis:db -i -t ubuntu:12.10 /bin/bash
Once inside our freshly created container we need to install Redis to get the
``redis-cli`` binary to test our connection.
Update your Docker container, install the Redis server. Once
installed, exit out of the Docker container.
.. code-block:: bash
apt-get update
apt-get -y install redis-server
service redis-server stop
apt-get install redis-server
exit
Now we can test the connection. Firstly, let's look at the available environmental
variables in our web application container. We can use these to get the IP and port
of our ``redis`` container.
Snapshot the installation
-------------------------
.. code-block:: bash
env
. . .
DB_NAME=/violet_wolf/db
DB_PORT_6379_TCP_PORT=6379
DB_PORT=tcp://172.17.0.33:6379
DB_PORT_6379_TCP=tcp://172.17.0.33:6379
DB_PORT_6379_TCP_ADDR=172.17.0.33
DB_PORT_6379_TCP_PROTO=tcp
docker ps -a # grab the container id (this will be the first one in the list)
docker commit <container_id> <your username>/redis
We can see that we've got a small list of environmental varaibles prefixed with ``DB``.
The ``DB`` comes from the link alias specified when we launched the container. Let's use
the ``DB_PORT_6379_TCP_ADDR`` variable to connect to our Redis container.
Run the service
---------------
Running the service with `-d` runs the container in detached mode, leaving the
container running in the background. Use your snapshot.
.. code-block:: bash
redis-cli -h $DB_PORT_6379_TCP_ADDR
redis 172.17.0.33:6379>
redis 172.17.0.33:6379> set docker awesome
sudo docker run -d -p 6379 <your username>/redis /usr/bin/redis-server
Test 1
++++++
Connect to the container with the redis-cli.
.. code-block:: bash
sudo docker ps # grab the new container id
sudo docker inspect <container_id> # grab the ipaddress of the container
redis-cli -h <ipaddress> -p 6379
redis 10.0.3.32:6379> set docker awesome
OK
redis 172.17.0.33:6379> get docker

We could easily use this or other environment variables in our web application to make a
connection to our ``redis`` container.
