Previously, the list of domain names to which a theme was assigned had to be
specified manually. Now, the themes are automatically assigned to the LMS and
the CMS, both in development and production modes.
When upgrading mongodb, the mongodb container takes a little while to become
ready. Running the "exec" command thus triggers an error:
docker-compose -f /path/to/env/local/docker-compose.yml -f /path/to/env/local/docker-compose.prod.yml --project-name tutor_local exec mongodb mongo --eval db.adminCommand({ setF
eatureCompatibilityVersion: "4.0" })
MongoDB shell version v4.0.24
connecting to: mongodb://127.0.0.1:27017/?gssapiServiceName=mongodb

We add a "sleep" statement to the upgrade process to ensure that the mongodb
container is available.
An issue with the latest release of docker-compose was reported here:
https://discuss.overhang.io/t/undefined-entrypoint-throws-error-in-docker-compose-2-0-0-beta-4/1716
The mysql-job definition had an empty entrypoint (`[]`). This was causing the following error:
the initiation of mysql fails with “services.mysql-job.entrypoint must be a string …
Error: Command failed with status 15”
I can't remember at all why we had to define an empty entrypoint. It probably
has to do with the fact that we could not run `sh -e -c "..."` commands in
mysql jobs. Similarly, the k8s job definition sets `command: []`. I tested both
local and k8s deployments without these definitions and they work just fine. So
I guess we can get rid of them.
When disable a plugin that set config entried, such as the minio plugin, tutor was logging the following:
Disabling plugin minio...
Removed config entry OPENEDX_AWS_ACCESS_KEY=openedx
Removed config entry OPENEDX_AWS_SECRET_ACCESS_KEY={{ MINIO_AWS_SECRET_ACCESS_KEY }}
Plugin disabled
The config values were not rendered during printing, which is a shame, because
the whole point of this log line is to warn users of passwords/secrets that are
being removed. Here, we make sure that the config values are properly rendered.
The new logs are now:
Disabling plugin minio...
Removing config entry OPENEDX_AWS_ACCESS_KEY=openedx
Removing config entry OPENEDX_AWS_SECRET_ACCESS_KEY=64vpCVLxhDxBuNjakSrX4CQg
Plugin disabled
In most cases, it makes very little sense to edit the namespace that an
application is running in. Quite often, users are granted access to just one
namespace and don't have the necessary rights to edit the namespace -- and for
good security reasons. In such cases, the k8s namespace object already exists
and there is no need for the user to edit or create it. Here, what we do is
that we create the namespace only if it does not exist. This should solve quite
a few permission issues, notably for Openshift users.
When running `tutor local quickstart -p` we were getting the following error:
Usage: custom [OPTIONS] ARGS...
Try 'custom --help' for help.
Error: Missing argument 'ARGS...'.
The docker-compose command sometimes accept a single command ("pull") with zero
argument.
See: https://discuss.overhang.io/t/local-quickstart-not-working-when-pullimages-enabled/1526
I stumbled upon a bug that should have been detected by the type
checking. Turns out, considering that config is of type Dict[str, Any]
means that we can use just any method on all config values -- which is
terrible. I discovered this after I set `config["PLUGINS"] = None`:
this triggered a crash when I enabled a plugin.
We resolve this by making the Config type more explicit. We also take
the opportunity to remove a few cast statements.
This option is mostly useless to us in CI, as it attempts (and fails) to
update the base image when building the dev image. For good reason: the
base image of the dev image is the latest openedx, which has not been
pushed to docker.io at the time of building -_-
Annotations were generated with pyannotate:

We are running in strict mode, which is awesome!
This affects a large part of the code base, which might be an issue for
people running a fork of Tutor. Nonetheless, the behavior should not be
affected. If anything, this process has helped find and resolve a few
type-related bugs. Thus, this is not considered as a breaking change.
It made little sense to create dedicated context classes for local/dev.
Instead, we create local/dev compose methods which can be easily reused.
Also, we renamed the "scripts" module to better reflect its function.
We manage to get unit tests to run in a dedicated openedx-test container. Only
35 tests are failing (out of 17k). I suspect these tests are also failing in
the devstack.
This introduces a new dev/local command:
tutor dev bindmount CONTAINER PATH
And a new volume syntax:
tutor dev run --volume=PATH CONTAINER
This syntax automatically bind-mounts folders from the tutorroot/volumes
directory, which is pretty nifty.
- 💥[Improvement] Upgrade Open edX to Koa
- 💥 Setting changes:
- The ``ACTIVATE_HTTPS`` setting was renamed to ``ENABLE_HTTPS``.
- Other ``ACTIVATE_*`` variables were all renamed to ``RUN_*``.
- The ``WEB_PROXY`` setting was removed and ``RUN_CADDY`` was added.
- The ``NGINX_HTTPS_PORT`` setting is deprecated.
- Architectural changes:
- Use Caddy as a web proxy for automated SSL/TLS certificate generation:
- Nginx no longer listens to port 443 for https traffic
- The Caddy configuration file comes with a new ``caddyfile`` patch for much simpler SSL/TLS management.
- Configuration files for web proxies are no longer provided.
- Kubernetes deployment no longer requires setting up a custom Ingress resource or custom manager.
- Gunicorn and Whitenoise are replaced by uwsgi: this increases boostrap performance and makes it no longer necessary to mount media folders in the Nginx container.
- Replace memcached and rabbitmq by redis.
- Additional features:
- Make it possible to disable all plugins at once with ``plugins disable all``.
- Add ``tutor k8s wait`` command to wait for a pod to become ready
- Faster, more reliable static assets with local memory caching
- Deprecation: proxy files for Apache and Nginx are no longer provided out of the box.
- Removed plugin `{{ patch (...) }}` statements:
- "https-create", "k8s-ingress-rules", "k8s-ingress-tls-hosts": these are no longer necessary. Instead, declare your app in the "caddyfile" patch.
- "local-docker-compose-nginx-volumes": this patch was primarily used to serve media assets. The recommended is now to serve assets with uwsgi.
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.
See https://discuss.overhang.io/t/kubernetes-ci-cd-pipeline/765/3
Here, we upgrade the Open edX platform from Ironwood to Juniper. This
upgrade does not come with many feature changes, but there are many
technical improvements under the hood:
- Upgrade from Python 2.7 to 3.5
- Upgrade from Mongodb v3.2 to v3.6
- Upgrade Ruby to 2.5.7
We took the opportunity to completely rething the way locally running
platforms should be accessed for testing purposes. It is no longer
possible to access a running platform from http://localhost and
http://studio.localhost. Instead, users should access
http://local.overhang.io and https://studio.local.overhang.io. This
drastically simplifies internal communication between Docker containers.
To upgrade, users should simply run:
tutor local quickstart
For Kubernetes platform, the upgrade process is outlined when running:
tutor k8s upgrade --from=ironwood
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.
