+# 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.

 .. code-block:: bash

-    docker run -cidfile /tmp/docker_test.cid ubuntu echo "test"
+    sudo docker run -cidfile /tmp/docker_test.cid ubuntu echo "test"
+
+This will create a container and print "test" to the console. The
+``cidfile`` flag makes docker attempt to create a new file and write the
+container ID to it. If the file exists already, docker will return an
+error. Docker will close this file when docker run exits.
+
+.. code-block:: bash
+
+   docker run mount -t tmpfs none /var/spool/squid
+
+This will *not* work, because by default, most potentially dangerous
+kernel capabilities are dropped; including ``cap_sys_admin`` (which is
+required to mount filesystems). However, the ``-privileged`` flag will
+allow it to run:
+
+.. code-block:: bash
+
+   docker run -privileged mount -t tmpfs none /var/spool/squid
+
+The ``-privileged`` flag gives *all* capabilities to the container,
+and it also lifts all the limitations enforced by the ``device``
+cgroup controller. In other words, the container can then do almost
+everything that the host can do. This flag exists to allow special
+use-cases, like running Docker within Docker.
+
+.. code-block:: bash
+
+   docker  run -w /path/to/dir/ -i -t  ubuntu pwd
+
+The ``-w`` lets the command beeing executed inside directory given, 
+here /path/to/dir/. If the path does not exists it is created inside the 
+container.
+
+.. code-block:: bash
+
+   docker  run  -v `pwd`:`pwd` -w `pwd` -i -t  ubuntu pwd
+
+The ``-v`` flag mounts the current working directory into the container. 
+The ``-w`` lets the command beeing executed inside the current 
+working directory, by changeing into the directory to the value
+returned by ``pwd``. So this combination executes the command
+using the container, but inside the current working directory.

+
+Building an Image with MongoDB
+==============================
+
+.. include:: example_header.inc
+
+The goal of this example is to show how you can build your own
+docker images with MongoDB preinstalled. We will do that by
+constructing a Dockerfile that downloads a base image, adds an
+apt source and installs the database software on Ubuntu.
+
+Creating a ``Dockerfile``
+++++++++++++++++++++++++
+
+Create an empty file called ``Dockerfile``:
+
+.. code-block:: bash
+
+    touch Dockerfile
+
+Next, define the parent image you want to use to build your own image on top of.
+Here, we’ll use `CentOS <https://index.docker.io/_/ubuntu/>`_ (tag: ``latest``)
+available on the `docker index`_:
+
+.. code-block:: bash
+
+    FROM    ubuntu:latest
+
+Since we want to be running the latest version of MongoDB we'll need to add the
+10gen repo to our apt sources list.
+
+.. code-block:: bash
+
+    # Add 10gen official apt source to the sources list
+    RUN apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
+    RUN echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | tee /etc/apt/sources.list.d/10gen.list
+
+Then, we don't want Ubuntu to complain about init not being available so we'll
+divert /sbin/initctl to /bin/true so it thinks everything is working.
+
+.. code-block:: bash
+
+    # Hack for initctl not being available in Ubuntu
+    RUN dpkg-divert --local --rename --add /sbin/initctl
+    RUN ln -s /bin/true /sbin/initctl
+
+Afterwards we'll be able to update our apt repositories and install MongoDB
+
+.. code-block:: bash
+
+    # Install MongoDB
+    RUN apt-get update
+    RUN apt-get install mongodb-10gen
+
+To run MongoDB we'll have to create the default data directory (because we want it to
+run without needing to provide a special configuration file)
+
+.. code-block:: bash
+
+    # Create the MongoDB data directory
+    RUN mkdir -p /data/db
+
+Finally, we'll expose the standard port that MongoDB runs on (27107)
+
+.. code-block:: bash
+
+    EXPOSE 27017
+
+Now, lets build the image which will go through the ``Dockerfile`` we made and
+run all of the commands.
+
+.. code-block:: bash
+
+    docker build -t <yourname>/mongodb .
+
+Now you should be able to run ``mongod`` as a daemon and be able to connect on
+the local port!
+
+.. code-block:: bash
+
+    # Regular style
+    MONGO_ID=$(docker run -d <yourname>/mongodb mongod)
+
+    # Lean and mean
+    MONGO_ID=$(docker run -d <yourname>/mongodb mongod --noprealloc --smallfiles)
+
+    # Check the logs out
+    docker logs $MONGO_ID
+
+    # Connect and play around
+    mongo --port <port you get from `docker ps`>

+PostgreSQL Service
+==================
+
+.. note::
+
+    A shorter version of `this blog post`_.
+
+.. note::
+
+    As of version 0.5.2, docker requires root privileges to run.
+    You have to either manually adjust your system configuration (permissions on
+    /var/run/docker.sock or sudo config), or prefix `docker` with `sudo`. Check
+    `this thread`_ for details.
+
+.. _this blog post: http://zaiste.net/2013/08/docker_postgresql_how_to/
+.. _this thread: https://groups.google.com/forum/?fromgroups#!topic/docker-club/P3xDLqmLp0E
+
+Installing PostgreSQL on Docker
+-------------------------------
+
+For clarity I won't be showing commands output.
+
+
+Run an interactive shell in Docker container.
+
+.. code-block:: bash
+
+    sudo docker run -i -t ubuntu /bin/bash
+
+Update its dependencies.
+
+.. code-block:: bash
+
+    apt-get update
+
+Install ``python-software-properies``.
+
+.. code-block:: bash
+
+    apt-get install python-software-properties
+    apt-get install software-properties-common
+
+Add Pitti's PostgreSQL repository. It contains the most recent stable release
+of PostgreSQL i.e. ``9.2``.
+
+.. code-block:: bash
+
+    add-apt-repository ppa:pitti/postgresql
+    apt-get update
+
+Finally, install PostgreSQL 9.2
+
+.. code-block:: bash
+
+    apt-get -y install postgresql-9.2 postgresql-client-9.2 postgresql-contrib-9.2
+
+Now, create a PostgreSQL superuser role that can create databases and
+other roles.  Following Vagrant's convention the role will be named
+`docker` with `docker` password assigned to it.
+
+.. code-block:: bash
+
+    sudo -u postgres createuser -P -d -r -s docker
+
+Create a test database also named ``docker`` owned by previously created ``docker``
+role.
+
+.. code-block:: bash
+
+    sudo -u postgres createdb -O docker docker
+
+Adjust PostgreSQL configuration so that remote connections to the
+database are possible. Make sure that inside
+``/etc/postgresql/9.2/main/pg_hba.conf`` you have following line:
+
+.. code-block:: bash
+
+    host    all             all             0.0.0.0/0               md5
+
+Additionaly, inside ``/etc/postgresql/9.2/main/postgresql.conf``
+uncomment ``listen_addresses`` so it is as follows:
+
+.. code-block:: bash
+
+    listen_addresses='*'
+
+*Note:* this PostgreSQL setup is for development only purposes. Refer
+to PostgreSQL documentation how to fine-tune these settings so that it
+is enough secure.
+
+Create an image and assign it a name. ``<container_id>`` is in the
+Bash prompt; you can also locate it using ``docker ps -a``.
+
+.. code-block:: bash
+
+    docker commit <container_id> <your username>/postgresql
+
+Finally, run PostgreSQL server via ``docker``.
+
+.. code-block:: bash
+
+    CONTAINER=$(sudo docker run -d -p 5432 \
+      -t <your username>/postgresql \
+      /bin/su postgres -c '/usr/lib/postgresql/9.2/bin/postgres \
+        -D /var/lib/postgresql/9.2/main \
+        -c config_file=/etc/postgresql/9.2/main/postgresql.conf')
+
+Connect the PostgreSQL server using ``psql``.
+
+.. code-block:: bash
+
+    CONTAINER_IP=$(sudo docker inspect $CONTAINER | grep IPAddress | awk '{ print $2 }' | tr -d ',"')
+    psql -h $CONTAINER_IP -p 5432 -d docker -U docker -W
+
+As before, create roles or databases if needed.
+
+.. code-block:: bash
+
+    psql (9.2.4)
+    Type "help" for help.
+
+    docker=# CREATE DATABASE foo OWNER=docker;
+    CREATE DATABASE
+
+Additionally, publish there your newly created image on Docker Index.
+
+.. code-block:: bash
+
+    sudo docker login
+    Username: <your username>
+    [...]
+
+.. code-block:: bash
+
+    sudo docker push <your username>/postgresql
+
+PostgreSQL service auto-launch
+------------------------------
+
+Running our image seems complicated. We have to specify the whole command with
+``docker run``. Let's simplify it so the service starts automatically when the
+container starts.
+
+.. code-block:: bash
+
+    sudo docker commit <container_id> <your username>/postgresql -run='{"Cmd": \
+      ["/bin/su", "postgres", "-c", "/usr/lib/postgresql/9.2/bin/postgres -D \
+      /var/lib/postgresql/9.2/main -c \
+      config_file=/etc/postgresql/9.2/main/postgresql.conf"], PortSpecs": ["5432"]}
+
+From now on, just type ``docker run <your username>/postgresql`` and
+PostgreSQL should automatically start.

-5. **Can I help by adding some questions and answers?**
+What does Docker add to just plain LXC?
+.......................................
+
+   Docker is not a replacement for LXC. "LXC" refers to capabilities
+   of the Linux kernel (specifically namespaces and control groups)
+   which allow sandboxing processes from one another, and controlling
+   their resource allocations.  On top of this low-level foundation of
+   kernel features, Docker offers a high-level tool with several
+   powerful functionalities:
+
+   * *Portable deployment across machines.* 
+      Docker defines a format for bundling an application and all its
+      dependencies into a single object which can be transferred to
+      any Docker-enabled machine, and executed there with the
+      guarantee that the execution environment exposed to the
+      application will be the same. LXC implements process sandboxing,
+      which is an important pre-requisite for portable deployment, but
+      that alone is not enough for portable deployment. If you sent me
+      a copy of your application installed in a custom LXC
+      configuration, it would almost certainly not run on my machine
+      the way it does on yours, because it is tied to your machine's
+      specific configuration: networking, storage, logging, distro,
+      etc. Docker defines an abstraction for these machine-specific
+      settings, so that the exact same Docker container can run -
+      unchanged - on many different machines, with many different
+      configurations.
+
+   * *Application-centric.* 
+      Docker is optimized for the deployment of applications, as
+      opposed to machines. This is reflected in its API, user
+      interface, design philosophy and documentation. By contrast, the
+      ``lxc`` helper scripts focus on containers as lightweight
+      machines - basically servers that boot faster and need less
+      RAM. We think there's more to containers than just that.
+
+   * *Automatic build.* 
+      Docker includes :ref:`a tool for developers to automatically
+      assemble a container from their source code <dockerbuilder>`,
+      with full control over application dependencies, build tools,
+      packaging etc. They are free to use ``make, maven, chef, puppet,
+      salt,`` Debian packages, RPMs, source tarballs, or any
+      combination of the above, regardless of the configuration of the
+      machines.
+
+   * *Versioning.* 
+      Docker includes git-like capabilities for tracking successive
+      versions of a container, inspecting the diff between versions,
+      committing new versions, rolling back etc. The history also
+      includes how a container was assembled and by whom, so you get
+      full traceability from the production server all the way back to
+      the upstream developer. Docker also implements incremental
+      uploads and downloads, similar to ``git pull``, so new versions
+      of a container can be transferred by only sending diffs.
+
+   * *Component re-use.* 
+      Any container can be used as a :ref:`"base image"
+      <base_image_def>` to create more specialized components. This
+      can be done manually or as part of an automated build. For
+      example you can prepare the ideal Python environment, and use it
+      as a base for 10 different applications. Your ideal Postgresql
+      setup can be re-used for all your future projects. And so on.
+
+   * *Sharing.*
+      Docker has access to a `public registry
+      <http://index.docker.io>`_ where thousands of people have
+      uploaded useful containers: anything from Redis, CouchDB,
+      Postgres to IRC bouncers to Rails app servers to Hadoop to base
+      images for various Linux distros. The :ref:`registry
+      <registryindexspec>` also includes an official "standard
+      library" of useful containers maintained by the Docker team. The
+      registry itself is open-source, so anyone can deploy their own
+      registry to store and transfer private containers, for internal
+      server deployments for example.
+
+   * *Tool ecosystem.* 
+      Docker defines an API for automating and customizing the
+      creation and deployment of containers. There are a huge number
+      of tools integrating with Docker to extend its
+      capabilities. PaaS-like deployment (Dokku, Deis, Flynn),
+      multi-node orchestration (Maestro, Salt, Mesos, Openstack Nova),
+      management dashboards (docker-ui, Openstack Horizon, Shipyard),
+      configuration management (Chef, Puppet), continuous integration
+      (Jenkins, Strider, Travis), etc. Docker is rapidly establishing
+      itself as the standard for container-based tooling.

-Bind Docker to another host/port or a unix socket
+Why ``sudo``?
+-------------
+
+The ``docker`` daemon always runs as root, and since ``docker``
+version 0.5.2, ``docker`` binds to a Unix socket instead of a TCP
+port. By default that Unix socket is owned by the user *root*, and so,
+by default, you can access it with ``sudo``.
+
+Starting in version 0.5.3, if you create a Unix group called *docker*
+and add users to it, then the ``docker`` daemon will make the
+ownership of the Unix socket read/writable by the *docker* group when
+the daemon starts. The ``docker`` daemon must always run as root, but
+if you run the ``docker`` client as a user in the *docker* group then
+you don't need to add ``sudo`` to all the client commands.

 -------------------------------------------------

-With -H it is possible to make the Docker daemon to listen on a specific ip and port. By default, it will listen on 127.0.0.1:4243 to allow only local connections but you can set it to 0.0.0.0:4243 or a specific host ip to give access to everybody.
+.. DANGER:: Changing the default ``docker`` daemon binding to a TCP
+   port or Unix *docker* user group will increase your security risks
+   by allowing non-root users to potentially gain *root* access on the
+   host (`e.g. #1369
+   <https://github.com/dotcloud/docker/issues/1369>`_). Make sure you

-	Each change should be formatted as ```BULLET CATEGORY: DESCRIPTION```
-
-	* BULLET is either ```-```, ```+``` or ```*```, to indicate a bugfix,

-		* Runtime
-

-
-### 3. Change VERSION in commands.go
-
-### 4. Run all tests
-
-	```bash
-	$ make test
-	```
-
-### 5. Commit and create a pull request
-
-	```bash
-	$ git add commands.go CHANGELOG.md
-	$ git commit -m "Bump version to $VERSION"
-	$ git push origin bump_$VERSION
-	```
-
-### 6. Get 2 other maintainers to validate the pull request
-
-### 7. Merge the pull request and apply tags
-
-	```bash
-	$ git checkout master
-	$ git merge bump_$VERSION
-	$ git tag -a v$VERSION # Don't forget the v!
-	$ git tag -f -a latest
-	$ git push
-	$ git push --tags
-	```
-
-### 8. Publish binaries
-
-	To run this you will need access to the release credentials.
-	Get them from [the infrastructure maintainers](https://github.com/dotcloud/docker/blob/master/hack/infrastructure/MAINTAINERS).
-
-	```bash
-	$ RELEASE_IMAGE=image_provided_by_infrastructure_maintainers
-	$ BUILD=$(docker run -d -e RELEASE_PPA=0 $RELEASE_IMAGE)
-	```
-
-	This will do 2 things:
-	
-	* It will build and upload the binaries on http://get.docker.io
-	* It will *test* the release on our Ubuntu PPA (a PPA is a community repository for ubuntu packages)
-
-	Wait for the build to complete.
-
-	```bash
-	$ docker wait $BUILD # This should print 0. If it doesn't, your build failed.
-	```
-
-	Check that the output looks OK. Here's an example of a correct output:
-
-	```bash
-	$ docker logs 2>&1 b4e7c8299d73 | grep -e 'Public URL' -e 'Successfully uploaded'
-	Public URL of the object is: http://get.docker.io.s3.amazonaws.com/builds/Linux/x86_64/docker-v0.4.7.tgz
-	Public URL of the object is: http://get.docker.io.s3.amazonaws.com/builds/Linux/x86_64/docker-latest.tgz
-	Successfully uploaded packages.
-	```
-
-	If you don't see 3 lines similar to this, something might be wrong. Check the full logs and try again.
-	
-
-### 9. Publish Ubuntu packages
-
-	If everything went well in the previous step, you can finalize the release by submitting the Ubuntu
-	packages.
-
-	```bash
-	$ RELEASE_IMAGE=image_provided_by_infrastructure_maintainers
-	$ docker run -e RELEASE_PPA=1 $RELEASE_IMAGE
-	```
-
-	If that goes well, Ubuntu Precise package is in its way. It will take anywhere from 0.5 to 30 hours
-	for the builders to complete their job depending on builder demand at this time. At this point, Quantal
-	and Raring packages need to be created using the Launchpad interface:
-	  https://launchpad.net/~dotcloud/+archive/lxc-docker/+packages
-
-	Notify [the packager maintainers](https://github.com/dotcloud/docker/blob/master/packaging/MAINTAINERS)
-	who will ensure PPA is ready.
-
-	Congratulations! You're done

+## A maintainer's guide to releasing Docker
+
+So you're in charge of a Docker release? Cool. Here's what to do.
+
+If your experience deviates from this document, please document the changes
+to keep it up-to-date.
+
+
+### 1. Pull from master and create a release branch
+
+```bash
+git checkout master
+git pull
+git checkout -b bump_$VERSION
+```
+
+### 2. Update CHANGELOG.md
+
+You can run this command for reference:
+
+```bash
+LAST_VERSION=$(git tag | grep -E "v[0-9\.]+$" | sort -nr | head -n 1)
+git log $LAST_VERSION..HEAD
+```
+
+Each change should be formatted as ```BULLET CATEGORY: DESCRIPTION```
+
+* BULLET is either ```-```, ```+``` or ```*```, to indicate a bugfix,
+  new feature or upgrade, respectively.
+
+* CATEGORY should describe which part of the project is affected.
+  Valid categories are:
+  * Builder
+  * Documentation
+  * Hack
+  * Packaging
+  * Remote API
+  * Runtime
+
+* DESCRIPTION: a concise description of the change that is relevant to the 
+  end-user, using the present tense. Changes should be described in terms 
+  of how they affect the user, for example "new feature X which allows Y", 
+  "fixed bug which caused X", "increased performance of Y".
+
+EXAMPLES:
+
+```
+ Builder: 'docker build -t FOO' applies the tag FOO to the newly built
+  container.
+* Runtime: improve detection of kernel version
+- Remote API: fix a bug in the optional unix socket transport
+```
+
+### 3. Change the contents of the VERSION file
+
+### 4. Run all tests
+
+```bash
+go test
+```
+
+### 5. Commit and create a pull request
+
+```bash
+git add CHANGELOG.md
+git commit -m "Bump version to $VERSION"
+git push origin bump_$VERSION
+```
+
+### 6. Get 2 other maintainers to validate the pull request
+
+### 7. Merge the pull request and apply tags
+
+```bash
+git checkout master
+git merge bump_$VERSION
+git tag -a v$VERSION # Don't forget the v!
+git tag -f -a latest
+git push
+git push --tags
+```
+
+### 8. Publish binaries
+
+To run this you will need access to the release credentials.
+Get them from [the infrastructure maintainers](
+https://github.com/dotcloud/docker/blob/master/hack/infrastructure/MAINTAINERS).
+
+```bash
+docker build -t releasedocker .
+docker run  \
+	-e AWS_S3_BUCKET=get-nightly.docker.io \
+	-e AWS_ACCESS_KEY=$(cat ~/.aws/access_key) \
+	-e AWS_SECRET_KEY=$(cat ~/.aws/secret_key) \
+	-e GPG_PASSPHRASE=supersecretsesame \
+	releasedocker
+```
+
+It will build and upload the binaries on the specified bucket (you should
+use get-nightly.docker.io for general testing, and once everything is fine,
+switch to get.docker.io).
+
+
+### 9. Rejoice!
+
+Congratulations! You're done.
