HTTPS is now fully supported. The ACTIVATE_HTTPS feature flag needs to
be set. Required domain names are LMS_HOST, preview.LMS_HOST and
CMS_HOST.
Close #46.
We no longer run the `configure` script on the host. Instead, we run a
container that generates the configuration files. This opens the way for
more complex configuration templates that would be written in jinja2.
More complex templates are required for feature flags, such as SSL,
XQUEUE, etc.
We replace the custom script wait-for-greenlight by dockerize: it is a
generic tool that allows for different services to be up. Also, on day,
it will allow us to generate config files dynamically (maybe).
Xqueue containers consist of two services: a gunicorn service, that
receives requests from LMS/CMS, and a worker service. I guess the worker
service receives orders from the gunicorn service, through rabbitmq.
(but I'm less than certain about that).
While adding xqueue containers, we refactored the way mysql databases
are created, and how the root password is loaded. Also, we silenced some
options from the configure script.
Images are no longer built locally, Instead, they are downloaded from
docker hub. This completely changes config file organisation. In
particular, we no longer copy configuration files to the original docker
image.
Demo course about pages were not available (and probably many other
pages as well) because the preview url was the same as the real url.
Kudos to @dannielarriola for solving this!
Close issues #11#7.
This allows the user to run their own devstack inside the containers.
Yay!
Also, we handle file permissions cleanly: in docker-entrypoint.sh we
chmod the data and edx-platform files to the same UID of the user on the
host machine. No more permission headaches!
When running "wait-for-mysql.sh", the "echo 'show tables' | manage.py
dbshell" command is always considered a success, even if the database is
unreachable ($? == 0). So we replace this command by a global system
check.
This closes #3.
