* Run as mailman user.
* Run mailman core process as a less-privileged mailman user.
* Add a `docker ps` to travis to know if any container died.
* Spit out more debug information in CI.
* Install su-exec properly.
Removing the build-deps package in a different layer doesn't really help because
of the way layered file systems work. They will exist in the image but appear to
be removed by whiteout files or something. This commit should reduce the size of
the mailman-core image considerably.
`mailman start` command does not nothing but parses the configuration and starts
the appropriate runners. The start command is implemented such that it forks the
master runner, which in-turn starts the all the rest of the runners. It turns
out that `master` is also exported as an console script which can directly be
started instead of running `mailman start` command. This makes containerizing
mailman much more easier.
- Add configuration for exim to work with mailman core.
- Add configuration to enable hyperkitty in mailman core.
- Add configuration to enable mailman_hyperkitty plugin.
- Add mailman_hyperkitty plugin and ipython in the core container.
- Set environemnt variables for Postgresql database in the compose file
- Set environment variables for uwsgi in the compose file
- Check if the postgresql container is up and accepting connections before
running any actual services.
This commit adds a lot of new code including the mailman's web
frontend. It includes a configuration file which can later be
configured to run required configs.
Also, the docker-compose file spins off the containers, sets up
appropriate volumes and links.
