This is not a security issue because ports 8000-8001 are not open to the
world; it should also drastically simplify the life of many people. See
for instance issues #30 and #34.
Also, we allow access to nginx on hostnames "localhost" and
"studio.localhost" for lms and cms, respectively. Again, this will
remove much of the confusion for many users.
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.
