Maintainer duty
===============

Ubuntu allows developers to use their PPA (Personal Package Archive)
repository. This is very convenient for the users as they just need to add
the PPA address, update their package database and use the apt-get tool.

For now, the official lxc-docker package is located on launchpad and can be
accessed adding the following line to /etc/apt/sources.list ::


  deb http://ppa.launchpad.net/dotcloud/lxc-docker/ubuntu precise main


Releasing a new package
~~~~~~~~~~~~~~~~~~~~~~~

The most relevant information to update is the packaging/ubuntu/changelog file:
Each new release should create a new first paragraph with new release version,
changes, and the maintainer information. The core of this paragraph is
located on CHANGELOG.md. Make sure to transcribe it and translate the formats
(eg: packaging/ubuntu/changelog uses 2 spaces for body change descriptions
instead of 1 space from CHANGELOG.md)

Assuming your PPA GPG signing key is on /media/usbdrive/docker.key, load it
into the GPG_KEY environment variable with::

  export GPG_KEY=`cat /media/usbdrive/docker.key`


After this is done and you are ready to upload the package to the PPA, you have
a couple of choices:

* Follow packaging/ubuntu/README.ubuntu to generate the actual source packages
  and upload them to the PPA

* Let vagrant do all the work for you::

  ( cd docker/packaging/ubuntu; vagrant up )
