This commit does a few things:
- Add the `--squash` option to the `awx-devel-build` make target. This reduces the resulting image size from 2.12 GB to 1.37 GB. I think we can get this down even more by inspecting the image contents.
- Reorganize commands so that the cache expires less often. Before this commit, any changes to the Makefile would essentially cause the entire image to rebuild.
- Break yum dependencies up into multiple lines. This makes it easier to see what changes in a diff.
- Use `n` to install our required version of node (rather `curl node | bash`). I’ve found this to be easier to maintain / more portable when working with other Dockerfiles.
- General organizational changes to make things easier to parse visually.
I wanted to pass `—user` to `docker-compose` up, but that option doesnt exist. To get around this, I had to record the uid on the host (CURRENT_UID), interpolate the variable in tools/docker-compose.yml, and detect that inside the container. I then piggy-backed on the /etc/passwd hack we use for scenarios with unpredictable uids.
I had to pull the git urls out of the main requirements files because in order to install offline (--no-index), we need pip to install from local package archives rather than cloning repo.
The weird `cat` thing going on in the Makefile is because we need to install everything as part of a single `pip install` transaction. Without this, installing only requirements_git.txt will result in dependencies getting unintentionally updated.
* Documentation of the developer variety
* Defaulting the COMPOSE_TAG to develop, can be overridden
* Automatic docker login assuming gcr login
* Including a manual build step as an alternative to gcr
* Make qpid container shut the f**k up when it's running
* Switch base tower devel image from u14.04 to c7
* Switch container image to build python dependencies into itself
instead of forcing it to be built on startup
* Upgrade venv pip to 8.1.2
* Neuter queue.py which was heavily tied to redis and was basically
orphaned code
* Alter local_settings to override default cache settings and use
memcached
* Alter local settings to refer to qpid instead of redis for celery
broker
* Purge redis python dependencies and add qpid and memcached
* Update docker-compose to purge redis and add qpid and memcached
