+
+.. _mongodb_image:
+
+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`>
+
+Sweet!

3.4 CMD
-------
- ``CMD <command>``
+CMD has three forms:
-The ``CMD`` instruction sets the command to be executed when running
-the image. This is functionally equivalent to running ``docker commit
--run '{"Cmd": <command>}'`` outside the builder.
+* ``CMD ["executable","param1","param2"]`` (like an *exec*, preferred form)
+* ``CMD ["param1","param2"]`` (as *default parameters to ENTRYPOINT*)
+* ``CMD command param1 param2`` (as a *shell*)
+
+There can only be one CMD in a Dockerfile. If you list more than one
+CMD then only the last CMD will take effect.
+
+**The main purpose of a CMD is to provide defaults for an executing
+container.** These defaults can include an executable, or they can
+omit the executable, in which case you must specify an ENTRYPOINT as
+well.
+
+When used in the shell or exec formats, the ``CMD`` instruction sets
+the command to be executed when running the image. This is
+functionally equivalent to running ``docker commit -run '{"Cmd":
+<command>}'`` outside the builder.
+
+If you use the *shell* form of the CMD, then the ``<command>`` will
+execute in ``/bin/sh -c``:
+
+.. code-block:: bash
+
+ FROM ubuntu
+ CMD echo "This is a test." | wc -
+
+If you want to **run your** ``<command>`` **without a shell** then you
+must express the command as a JSON array and give the full path to the
+executable. **This array form is the preferred format of CMD.** Any
+additional parameters must be individually expressed as strings in the
+array:
+
+.. code-block:: bash
+
+ FROM ubuntu
+ CMD ["/usr/bin/wc","--help"]
+
+If you would like your container to run the same executable every
+time, then you should consider using ``ENTRYPOINT`` in combination
+with ``CMD``. See :ref:`entrypoint_def`.
+
+If the user specifies arguments to ``docker run`` then they will

+have an effect.
+
+An ``ENTRYPOINT`` helps you to configure a container that you can run
+as an executable. That is, when you specify an ``ENTRYPOINT``, then
+the whole container runs as if it was just that executable.
+
+The ``ENTRYPOINT`` instruction adds an entry command that will **not**

+You can specify parameters either in the ENTRYPOINT JSON array (as in

+ENTRYPOINT will not be overridden by the ``docker run`` arguments, but
+parameters specified via CMD will be overridden by ``docker run``
+arguments.

+Like a ``CMD``, you can specify a plain string for the ENTRYPOINT and
+it will execute in ``/bin/sh -c``:

-
- ```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.
