- [Improvement] Fix tls certificate generation in k8s
- 💥[Improvement] Radically change the way jobs are run: we no longer
"exec", but instead run a dedicated container.
- 💥[Improvement] Upgrade k8s certificate issuer to
cert-manager.io/v1alpha2
- [Feature] Add SCORM XBlock to default openedx docker image
There are too many different ways to deploy an Ingress resource and to
generate SSL/TLS certificates: it's too much responsibility to make that
decision for the end user.
Running jobs was previously done with "exec". This was because it
allowed us to avoid copying too much container specification information
from the docker-compose/deployments files to the jobs files. However,
this was limiting:
- In order to run a job, the corresponding container had to be running.
This was particularly painful in Kubernetes, where containers are
crashing as long as migrations are not correctly run.
- Containers in which we need to run jobs needed to be present in the
docker-compose/deployments files. This is unnecessary, for example when
mysql is disabled, or in the case of the certbot container.
Now, we create dedicated jobs files, both for local and k8s deployment.
This introduces a little redundancy, but not too much. Note that
dependent containers are not listed in the docker-compose.jobs.yml file,
so an actual platform is still supposed to be running when we launch the
jobs.
This also introduces a subtle change: now, jobs go through the container
entrypoint prior to running. This is probably a good thing, as it will
avoid forgetting about incorrect environment variables.
In k8s, we find ourselves interacting way too much with the kubectl
utility. Parsing output from the CLI is a pain. So we need to switch to
the native kubernetes client library.
The "Certificate" objects are no longer required. As a consequence, the
"k8s-ingress-certificates" has become useless and should be removed from
plugins.
- [Feature] Make it easy to add custom translation strings to the
openedx Docker image
- [Improvement] Make it possible to rely on a different npm registry for
faster image building
Users can now add custom translation strings to a locale folder at build
time, very much in the same way as custom themes or requirements. This
is quite convenient, although is does require quite a bit of time to
rebuild the docker images.
During an incident at npmjs.org it was extremely difficult to pull
nodejs packages -- so we made it possible to pull from a custom
registry, deployed for instance with Verdaccio (https://verdaccio.org/).
- [Bugfix] Make sure all emails (including "password reset") are
properly saved to a local file in development mode (#315)
- [Improvement] Add `openedx-development-settings` patch to patch the
LMS and the CMS simultaneously in development
- [Bugfix] Fix missing celery tasks in the CMS
In development, emails sent from edx-platform were using the
"file_email" channel from edx-ace ("edX's automated communication
engine"). This channel was failing because it tries to write to a file
located in the /edx folder, which does not exist in tutor containers. To
fix this, we configure edx-ace to rely on the django email backend,
which itself is configured to send emails to a file in development. It
turns out that this backend was also configured to store emails in a
file located in the /edx folder, so we had to add the standard
EMAIL_FILE_PATH django setting to our development settings.
It was easier to reconfigure the django file email backend than the
edx-ace file_email channel because the output path of the latter cannot
be modified by a setting.
Note that this causes all emails to be stored in local files instead of
being sent to actual recipients. This is the default behaviour in Open
edX, and indeed in most default django apps (in development). This is a
good thing! If, for some reason, developers would like to try out email
sending during development, they should modify the EMAIL_BACKEND
setting and set it to 'django.core.mail.backends.smtp.EmailBackend'.
This is quite easy to achieve with the help of a plugin:
name: sendemailsindev
version: 0.1.0
patches:
openedx-development-settings: |
# actually send emails in dev
EMAIL_BACKEND = "django.core.mail.backends.smtp.EmailBackend"
Close #315
When we were changing unit titles in the CMS, the changes were taking a
long time to be reflected in the LMS. That's because the cache key that
corresponds to the course structure was not being updated. It was the
responsibility of an asynchronous LMS celery worker to update this cache
entry. However, this was impossible in most cases because tasks
triggered in the CMS were only processed by CMS workers. That is, unless
we are using a custom celery router:
https://celery.readthedocs.io/en/latest/userguide/routing.html#routers
This is what edx-platform does in the devstack: certain CMS tasks are
forwarded both to CMS and to LMS workers. This is achieved by defining
the ALTERNATE_WORKER_QUEUES="lms" django setting in the CMS.
Adding this setting to Tutor solves the problem in production. However,
in development mode Open edX runs without workers
(`CELERY_ALWAYS_EAGER=True`). This means that the course structure will
not be automatically updated when running `tutor dev` commands, which is
a shame. The alternative is to define the
"block_structure.invalidate_cache_on_publish" waffle switch. This can be
done from the UI (in /admin/waffle/switch/add/) or by running:
tutor dev run lms ./manage.py lms waffle_switch block_structure.invalidate_cache_on_publish on --create
However, this flag seems to slow down access to the LMS for the first
user who tries to access the course after it has been updated.

- [Feature] Add `encrypt` template filter to conveniently add
htpasswd-based authentication to nginx
- [Bugfix] Fix "missing tty" during init in cron jobs
Client-side translations are stored in "djangojs.js" files. Supposedly,
these files were properly compiled prior to the Ironwood release -- but
this is not the case, so we need to re-generate them.
Also, we need to re-generate the djangojs.js files for the custom,
downloaded locales. The assets collection settings are also fixed to
take into account the separate locale folder.
This step needs to happen prior to static assets collection, as the
djangojs files are collected to the staticfiles/ folder.

tls renewal and generation was failing in cron jobs because of "The

When running "bundle exec rake search:initialize" in the forum, we were
getting the following error:
/openedx/ruby/lib/ruby/site_ruby/2.4.0/rubygems/resolver.rb:235:in `search_for': Unable to resolve dependency: user requested 'did_you_mean (= 1.1.0)' (Gem::UnsatisfiableDependencyError)
It happens this error suddently happened because rubygems-update was not
pinned to a specific version. v3.0.4 was working and v3.1.2 was not.
As it happens, we don't need rubygems-update, so we simply get rid of it
entirely.
To do so, we had to create a new log_format.
Plugin developers are strongly encouraged to start using this log format
by adding the `access_log /var/log/nginx/access.log tutor;` directive to
their extra nginx configurations.
In order to load this log format early, the `tutor.conf` config file had
to be renamed to something early in the alphabet... (hence starting by
an underscore) Older users would face an error on nginx reload, so older
"tutor.conf" files are automatically removed on config save.
Previously, a common error when restarting e.g: the lms or the cms was
that nginx redirected to the wrong container. For instance:
access studio.localhost
tutor local restart lms cms
access studio.localhost
In the second call to studio.localhost, we were frequently trying to
access the LMS, which resulted in a 400 error.
We solve this issue by setting a TTL of 10s on the nginx proxy name
resolution.

The management plugin exposes an http API that makes it possible to
monitor rabbitmq. By default, we do not expose the management dashboard.
As a consequence, the API is only usable by other internal containers.
- [Improvement] Switch edx-platform from open-release/ironwood.2 tag to
the open-release/ironwood.master branch
- [Security] Upgrade django to 1.11.28
- [Improvement] Make it possible to configure the elasticsearch heap
size
- [Bugfix] Fix broken elasticsearch environment variables
- [Improvement] Restore more recent Android app version (#289).
There are too many patches on top of ironwood.2, and it's not practical
to pull them all one by one. We still want to build on top of a specific
version, and not a branch, so we use a dirty hack to guarantee that the
docker image is properly rebuilt by CI when we change it.
Because we are running a version of elasticsearch older than Methusalem,
the docker environment variables were not properly taken into account.
For instance, the cluster name and "mlockall" settings were incorrect,
as we could see by running:
$ tutor local run lms curl elasticsearch:9200 | grep cluster_name
...
"cluster_name" : "elasticsearch",
$ tutor local run lms curl elasticsearch:9200/_nodes/process?pretty | grep mlock
...
"mlockall" : false
See
https://discuss.overhang.io/t/elastic-container-is-not-being-removed/312/3
for discussion.
This fix also introduces a new tutor configuration setting to adjust the
elasticsearch heap size.
A prior change used the ironwood.1 tag to build the Android app in an
attempt to solve #289. Turns out that this change was unnecessary. So
here we revert to a more recent release of the Android app. Instead of
building from the master branch (which might create suprises) we build
from a fixed release tag.
The source repo and version are customisable via build arguments.
This is for supporting json-based plugins. The great thing about this
change is that it allows us to easily print plugin version numbers in
`plugins list`.
- [Bugfix] Fix oauth authentication in dev mode
- [Improvement] Upgrade to the 3.7 docker-compose syntax
- [Improvement] The `dev runserver` command can now be run for just any
service
- 💥[Feature] `dev run/exec` commands now support generic options which
are passed to docker-compose. Consequently, defining the
`TUTOR_EDX_PLATFORM_PATH` environment variable no longer works. Instead,
users are encouraged to explicitely pass the `-v` option, define a
command alias or create a `docker-compose.override.yml` file.
By de-duplicating the code between dev.py and local.py, we are able to
support more docker-compose run/up/stop options passed from tutor. To do
so, we had to disable some features, such as automatically mounting the
edx-platform repo when the TUTOR_EDX_PLATFORM_PATH environment variable
was defined.

"Course visibility In Catalog" advanced CMS setting was being ignored
because the default the COURSE_CATALOG_VISIBILITY_PERMISSION and
COURSE_ABOUT_VISIBILITY_PERMISSION settings were incorrectly set to the
legacy default, which "see_exists".

It makes more sense to document this command instead of adding it to the
`local` commands. If need be, in the future we should be able to re-add
it as a plugin.
This command adds a burden on the `local` and `k8s` command. It does not
make sense to provide this command out of the box, and not other
administration commands. Instead, we should better document how to run
regular `manage.py` commands from tutor.
Close #269.

- faster chown in development
- mounted requirements volume in development
- fix static assets issues
- bundled ipdb/vim/... packages, which are convenient for development
