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.
I want to be able to distribute docker-compose.yaml without any dependencies. In
order to do that, I should make it pull stable images from hub.docker.com
instead of trying to build them locally. This will avoid users running untested
code from the github repo instead of using the tested version on docker hub.
Checking for the wrong database URL caused the mailman core to always use an
sqlite database even when another database is defined. This commit fixes that.
`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.
django.
- -z Does not check properly if the DATABASE_URL is defined or not. It evaluates
to True if it is not set or set to ''
- Remove SECURE_SSL_REDIRECT in the django settings because this deployment is
meant to behind Nginx which decrypts SSL packets.
- Force mailman to start even with a lock. This _may_ not be the best idea but
for now if everything is followed according to this guide.
Following 12factor principle for app development, all the configuration
variables for the docker images can now be setup using environment vars.
The default values are set using the run.sh script in both mailman-web
and mailman-core containers.
Mailman-core is now run by "run.sh" which traps SIGTERM and performs
mailman stop for graceful exit of mailman core.
- Download source code as zip from gitlab instead of git+https because speed.
- Check if the $DATABASE_URL is not defined, use a default sqlite database.
- Use dj-database-url package to set database in django settings using
DATABASE_URL environment variable.
- Use UWSGI_LOG_URL as the URL for UWSGI logging and set it to a default value
if it has not been defined.
- If the logs file doesn't exist, create it so that django doesn't complain about
non-existent log files.
- If the settings_local.py exist, copy it too along with settings.py
