PR #619 set the EDX_PLATFORM_VERSION build arg's default to
OPENEDX_COMMON_VERSION. While this works fine for setting a
non-default branch to run edx code from (say, "master"), it may break
if the user sets OPENEDX_COMMON_VERSION to a branch or tag name that
does not exist upstream in repositories *other than*
EDX_PLATFORM_REPOSITORY.
Thus, introduce a separate configuration parameter,
EDX_PLATFORM_VERSION, to match the build arg of the same name. Set its
default to OPENEDX_COMMON_VERSION.
This way, the user can deploy an arbitrarily-named fork of
edx-platform, while retaining the default OPENEDX_COMMON_VERSION
(like, for example "open-release/maple.3") for everything else.
Previously, the only way for Tutor users to use a fork of edx-platform
or a custom NPM registry was to use build args during the image build.
This is suboptimal in the case of automatically building images from
CI pipelines, which may want to auto-detect when an image needs to be
rebuilt based on config.yml changes.
In addition, the EDX_PLATFORM_VERSION build argument can already be
set via a corresponding config.yml parameter (OPENEDX_COMMON_VERSION),
so it's reasonable to follow that precedent and also introduce
config.yml parameters to correspond with the EDX_PLATFORM_REPOSITORY
and NPM_REGISTRY build arguments.
Thus, introduce two new configuration parameters:
- EDX_PLATFORM_REPOSITORY
- NPM_REGISTRY
These parameters can now optionally be used instead of the
aforementioned build args.
- A shared cookie domain between lms and cms is no longer recommended:
https://github.com/edx/edx-platform/blob/master/docs/guides/studio_oauth.rst
- refactor: clean mounted data folder in lms/cms. In Lilac, the
bind-mounted lms/data and cms/data folders are a mess because new
folders are created there for every new course organisation. These
folders are empty. As far as we know they are useless... With this
change we move these folders to a dedicated "modulestore" subdirectory;
which corresponds better to the initial intent of the fs_root setting.
- fix: frontend failure during login to the lms. See:
https://github.com/openedx/build-test-release-wg/issues/104
- feat: move all forum-related code to a dedicated plugin. Forum is an
optional feature, and as such it deserves its own plugin. Starting from
Maple, users will be able to install the forum from
https://github.com/overhangio/tutor-forum/
- migrate from DCS_* session cookie settings to SESSION_*. That's
because edx-platform no longer depends on django-cookies-samesite. Close
https://github.com/openedx/build-test-release-wg/issues/110
- get rid of tons of deprecation warnings in the lms/cms
- feat: make it possible to point to themed assets. Cherry-picking this
change makes it possible to point to themed assets with a theme-agnostic
url, notably from MFEs.
- Install all official plugins as part of the `tutor[full]` package.
- Don't print error messages about loading plugins during autocompletion.
- Prompt for image building when upgrading from one release to the next.
- Add `tutor local start --skip-build` option to skip building Docker images.
Close #450.

With this change, containers are no longer run as "root" but as unprivileged
users. This is necessary in some environments, notably some Kubernetes
clusters.
To make this possible, we need to manually fix bind-mounted volumes in
docker-compose. This is pretty much equivalent to the behaviour in Kubernetes,
where permissions are fixed at runtime if the volume owner is incorrect. Thus,
we have a consistent behaviour between docker-compose and Kubernetes.
We achieve this by bind-mounting some repos inside "*-permissions" services.
These services run as root user on docker-compose and will fix the required
permissions, as per build/permissions/setowner.sh These services simply do not
run on Kubernetes, where we don't rely on bind-mounted volumes. There, we make
use of Kubernete's built-in volume ownership feature.
With this change, we get rid of the "openedx-dev" Docker image, in the sense
that it no longer has its own Dockerfile. Instead, the dev image is now simply
a different target in the multi-layer openedx Docker image. This makes it much
faster to build the openedx-dev image.
Because we declare the APP_USER_ID in the dev/docker-compose.yml file, we need
to pass the user ID from the host there. The only way to achieve that is with a
tutor config variable. The downside of this approach is that the
dev/docker-compose.yml file is no longer portable from one machine to the next.
We consider that this is not such a big issue, as it affects the development
environment only.
We take this opportunity to replace the base image of the "forum" image. There
is now no need to re-install ruby inside the image. The total image size is
only decreased by 10%, but re-building the image is faster.
In order to run the smtp service as non-root, we switch from namshi/smtp to
devture/exim-relay. This change should be backward-compatible.
Note that the nginx container remains privileged. We could switch to
nginxinc/nginx-unprivileged, but it's probably not worth the effort, as we are
considering to get rid of the nginx container altogether.
Close #323.
Added OPENEDX_EXTRA_PIP_REQUIREMENTS setting, which allows to specify
extra pip packages that should be installed.
Moved "openedx-scorm-xblock" package from Dockerfile to the new setting
in the config.yml.
There is too much information in each of the local/k8s/dev docs pages. The
"guides" that are listed in each one of those pages are moved either to "common
tasks" or to a dedicated "tutorials" section. This paves the way for more
comprehensive tutorials, where we describe how to run the latest master
branches of Open edX.
I am well aware that, as they stand, the tutorials are of poor quality and
should be rewritten. This is a task for another day/commit. For now, we only
move the contents to a separate part of the docs.
Also, we should add a "reference" section to the docs, where we add the result
of `tutor <subcommand> --help`.
We remove security patches and custom fixes which are now part of koa.3.
We take the opportunity to make it possible to build the openedx Docker image
without relying on a corresponding openedx-i18n repo tag: often, we want to
test whether the image simply builds successfully, and we don't need up-to-date
translations. For those cases, it's now possible to pass the `-a
OPENEDX_I18N_VERSION=oldertag` build argument.
- 💥[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.

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
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/).
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.
