In the LMS, some resources where loaded from localhost:18000. For
instance: http://localhost:18000/static/images/logo.png
This was due to the fact that the LMS_BASE, LMS_ROOT_URL and thus
SITE_NAME settings are overwritten by the devstack settings, so we need
to define them again in development.
This drastically simplifies volume management, as it is no longer
necessary to manually copy static assets from the docker image to the
bind-mounted volume.
This deprecates the "k8s-deployments-nginx-init-containers" patch, as we
no longer need to init the nginx container. Plugins are encouraged to
start using whitenoise as well for serving static assets.
TODO:
- test media serving: DOES NOT WORK. Whitenoise was designed to serve a
fixed list of static files. Godammit.
- compare performances
This reduces the size of the final image from 3.25Gb to 2.8Gb. Also, it
should be faster to rebuild the image in most cases. For instance, we
will not have to re-install nodejs requirements after part of the
edx-platform repo was modified.
- [Security] Apply edx-platform upstream xss security fixes ([pull
request](https://github.com/edx/edx-platform/pull/24568))
- 💥[Feature] Make it possible to override the docker registry for just
a few services by setting `DOCKER_IMAGE_SERVICENAME` values.
Previously, it was not possible to override the docker registry for just
one or a few services. Setting the DOCKER_REGISTRY configuration
parameter would apply to all images. This was inconvenient. To resolve
this, we include the docker registry value in the DOCKER_IMAGE_*
configuration parameters. This allows users to override the docker
registry individually by defining the DOCKER_IMAGE_SERVICENAME
configuration parameter.

The dashboard is available at /sysadmin. It's a CRUD interface for
managing users and courses.
Enabling this interface required that the DATA_DIR setting was not a
string, but a Path object.
Close #353.
In k8s, creating a user is an interactive command, so it needs to run in
exec. Thus, the DJANGO_SETTINGS_MODULE needs to be defined for this
command.
Close #344
In production, the ALTERNATE_WORKER_QUEUES setting is overridden by ""
(empty string). This might prevent LMS from sending tasks to the CMS. We
have not seen this issue emerge yet, but better be safe than sorry.
We must be careful not to process the tasks from the CMS, just like for
the CMS worker which does not process the tasks from the LMS.
Half of the tasks from edx.lms.core.default celery queue were being
processed by the CMS worker. Unfortunately, this CMS worker crashes on
some of those tasks. For instance, activation emails complain of a
missing "django_markup" template tag library because "xss_utils" is not
part of the installed app in the CMS.
The problem is that we need this edx.lms.core.default queue to be part
of the CELERY_QUEUES in the cms in order to send tasks from the CMS to
the LMS. The trick to resolve this situation is to ask the CMS celery
worker to not process the tasks from this queue.
To debug this issue, run in the LMS:
from student.tasks import send_activation_email
send_activation_email("{}")
Then watch the logs of the lms and cms workers. If the CMS workers picks
up this task (50% of the time prior to this change) then we have an
issue.

"tutor ui" was failing miserably, printing a lot of garbled characters
in the shell. In fact, a FileNotFound error was being raised and
automatically caught by the ui command. When removing the catch all,
this was the error that was raised:
FileNotFoundError: [Errno 2] No such file or directory:
'/tmp/_MEIimsqmq/wcwidth/version.json' │
