Docker image builder for Openstack clients (aka OSCs docker builder)
====================================================================

|Latest Version| |Downloads| |Code Issues| |CircleCI|


A lot of people need install/update/upgrade/downgrade any Openstack
python client in any time. Thanks to Docker containers it is easy to get an
isolated environment with all Openstack clients of specific upstream versions
that you wish.

Pre-requisites
==============

List of pre-requisites :

-  docker image: Ensure that there is an official python docker image
   for the provided python version parameter.
-  tox : All clients are using tox, and python version parameter will be
   matched in env list.
-  common release: All clients have to have the same release, in other cases
   you must specify a different release (by property 'release'
   in the osc.yml file) to override global release parameter. For
   example, in the osc.yml you may see that gnocchi client has 'master'
   release instead of 'stable/newton'.

Build a docker image with OSCs
==============================

This module can be installed by pip:

::

    $ pip install osc-docker-builder

Best way to get help about the command is :

::

    osc-builder --help
    usage: ocs [-h] [-bp BUILD_PATH] [-f CONFIG_FILE] [-pv PYTHON_VERSION]
               [-r RELEASE] [-c CLIENTS] [-sf] [-v]

    Build a docker image with all Openstack clients that you want for a specific
    upstream branch and python version

    optional arguments:
      -h, --help            show this help message and exit
      -bp BUILD_PATH, --build-path BUILD_PATH
                            The build path where files are written.
      -f CONFIG_FILE, --config-file CONFIG_FILE
                            A YAML config file.
      -pv PYTHON_VERSION, --python-version PYTHON_VERSION
                            Python version for docker image
                            base(https://hub.docker.com/_/python/).For example :
                            2.7, 3.5.2
      -r RELEASE, --release RELEASE
                            Upstream release.
      -c CLIENTS, --clients CLIENTS
                            Provide all openstack python clients that you want.By
                            defaults only python-openstackclient will be
                            installed.
      -sf, --skip-fails     Skip failures and create the image.
      -v, --verbose         Show details.


Ready for action ?, suppose that you want to create a docker image for
these python version and Openstack clients:

::

    osc-builder --python-version 3.4 --clients openstack --clients heat --release stable/newton --build-path /tmp/osc-docker-builder

I recommend using a config file (which could be controlled by a
version control system):

::

    osc-builder -f osc.yml



Running and using docker container
==================================

For example, run a container based on latest image for python client 2.7
and release stable/newton :

::

    $ docker run -it -d --name osc engapa/osc:2.7-stable_newton-latest
    1f395d7273b99b734725fcbab4ebd05082f21978e0c4e3104cc8332c7430920d
    $ docker ps
    CONTAINER ID   IMAGE                               COMMAND     CREATED        STATUS       PORTS  NAMES
    1f395d7273b9   engapa/osc:2.7-stable_newton-latest "/bin/bash" 2 seconds ago  Up 3 seconds        osc

    $ docker attach 1f395d7273b9
    root@1f395d7273b9:# pip list --format columns | grep -i "^python-.*client"
    python-openstackclient         3.2.1.dev10 /src/python-openstackclient
    python-saharaclient            0.18.1.dev1 /src/python-saharaclient
    python-searchlightclient       1.0.1.dev1  /src/python-searchlightclient
    python-senlinclient            1.0.1.dev14 /src/python-senlinclient
    python-solumclient             2.1.2.dev2  /src/python-solumclient
    python-swiftclient             3.1.1.dev1  /src/python-swiftclient
    ...
    root@1f395d7273b9:/#


If you want to update all python client versions (if provided release was a branch , e.g. : master) just execute this command within the container:

::

    $ docker attach 1f395d7273b9
    root@1f395d7273b9:/root# pip install -U -r requirements.txt


An interesting module of openstack is 'os-client-config', it aims you to use a cloud configuration file shared by volume mount point (at "/root", "/root/.config/openstack" or "/etc/openstack" directory):

::

    $ cat << EOF > cloud.yml
    > clouds:
    >   spaincloud:
    >     auth:
    >       username: engapa
    >       password: XXXXXXXXX
    >       project_name: OSOOS
    >       auth_url: 'https://spaincloud.com:5001/v2.0'
    >     region_name: SpainSalamanca
    >     dns_api_version: 1
    > EOF
    $ docker run -it --name osc -v $(pwd)/clouds.yml:/root/.config/openstack/clouds.yml engapa/osc:2.7-stable_newton-latest
    root@1536ac361c6c:~# openstack --os-cloud spaincloud server list
    ...
