Manual configuration via the `MOUNTS` setting was inconvenient. We
(re)introduce a new(ish) `tutor mounts` command. Old timers will perhaps
remember that we used to have a `tutor bindmount` command. Well, it's
back! But better and different.
This is an important change, where we get remove the previous `--mount`
option, and instead opt for persistent bind-mounts.
Persistent bind mounts have several advantages:
- They make it easier to remember which folders need to be bind-mounted.
- Code is *much* less clunky, as we no longer need to generate temporary
docker-compose files.
- They allow us to bind-mount host directories *at build time* using the
buildx `--build-context` option.
- The transition from development to production becomes much easier, as
images will automatically be built using the host repo.
The only drawback is that persistent bind-mounts are slightly less
portable: when a config.yml file is moved to a different folder, many
things will break if the repo is not checked out in the same path.
For instance, this is how to start working on a local fork of
edx-platform:
tutor config save --append MOUNTS=/path/to/edx-platform
And that's all there is to it. No, this fork will be used whenever we
run:
tutor images build openedx
tutor local start
tutor dev start
This change is made possible by huge improvements in the build time
performance. These improvements make it convenient to re-build Docker
images often.

Among other changes: ORA2 file uploads were stored in a folder named
"SET-ME-PLEASE (ex. bucket-name)" (sigh). With this change, the folder
should be automatically renamed to "openedxuploads". This issue has been
occuring since June 2019... (sigh²)
Close #707
Before this commit, setting up an edx-platform development environment
took multiple steps:
tutor dev launch
tutor dev run --mount=/path/to/edx-platform lms bash
>> pip install -e .
>> npm clean-install
>> openedx-assets build --env=dev
This commit moves the steps under ``run`` into an init task, which
is automatically run by ``launch``. Thus, setup is now one command:
tutor dev launch --mount=edx-platform
These extra init steps are only applicable when bind-mounting
edx-platform (because bind-mounting the repository overrides
some important artifacts that exist on the image, which must be
re-generated). Thus, the new init tasks exists early if it detects
that it is *not* operating on a bind-mounted repository.
Finally, we try to simplify the Open edX development docs so that
it is clearer how bind-mounting fits into the development process.
These bind-mounts:
* ../build/openedx/themes:/openedx/themes
* ../build/openedx/requirements:/openedx/requirements
existed in the dev lms and cms containers, but they did
not exist in the lms-job and cms-job containers.
This means that themes and requirements that were *built into the
image* would exist in the job containers, but live updates to the
themes and requirements would not apply.
To resolve this, we set ``volumes:`` on the lms-job and cms-job
services so that they match the volumes for the normal lms and
cms services.

`quickstart` is being renamed to `launch` and deprecated in favor of
using `launch`. The `quickstart` function temporarily aliases to
`launch`. Further mentions of `quickstart` have been changed to
reference `launch` instead.
We are indicating that this change is breaking 💥 to encourage people to
migrate their scripts right away!
PYTHONBREAKPOINT has been exposed as an environment variable in
the openedx Dockerfile available to be changed in config.yml. The docs have also been changed to recommend using
breakpoint and explaining how PYTHONBREAKPOINT can be modified to use a
custom debugger.

Now that Tutor is the official community installation for Open edX, it no
longer makes sense to host a forum that is separate from the general Open edX
forum. Moving conversations there will encourage cross-communication between
projects and maintainers. This change is part of a larger overhaul described in
this Tutor enhancement proposal (TEP):
https://discuss.overhang.io/t/tep-rethinking-the-tutor-maintainers-program/2724
In the future, plugin maintainers should point their users to the Open edX
forum as well. They are encouraged to create dedicated "tutor-pluginnname" tags
on the forum and to set their notification level to "watching".
`copyfrom` copies data from a container to the local filesystem. It's similar
to bindmount, but less clunky, and more intuitive. Also, it plays along great
with `--mount`. Eventually we'll just get rid of the `bindmount` command and
the `--volume` option.
`tutor dev runserver` will be removed in a future release.
Developers are encouraged to use `tutor dev start` instead,
which is more flexible and provides a consistent interface
with `tutor local start`.
As part of this deprecation, we enable the `tty` and
`stdin_open` options on development docker-compose
services. This will allow developers to use `start`
for breakpoint debugging, which was previously only
availble via `runserver`. Several parallel PRs have
been merged in order to make the same change in the
development services of the official plugins.
Although `start` does not support the `--volume` option,
it supports a more-powerful `--mount` option. So, where
developers previously used:
tutor dev runserver --volume ...
to bind-mount host directories, they should now use:
tutor dev start --mount ...
Resolves https://github.com/overhangio/2u-tutor-adoption/issues/61
The `--mount` option is available both with `tutor local`
and `tutor dev` commands. It allows users to easily bind-mount containers from
the host to containers. Yes, I know, we already provide that possibility with
the `bindmount` command and the `--volume=/path/` option. But these suffer from
the following drawbacks:
- They are difficult to understand.
- The "bindmount" command name does not make much sense.
- It's not convenient to mount an arbitrary folder from the host to multiple
containers, such as the many lms/cms containers (web apps, celery workers and
job runners).
To address this situation, we now recommend to make use of --mount:
1. `--mount=service1[,service2,...]:/host/path:/container/path`: manually mount
`/host/path` to `/container/path` in container "service1" (and "service2").
2. `--mount=/host/path`: use the new v1 plugin API to discover plugins that
will detect this option and select the right containers in which to bind-mount
volumes. This is really nifty...

Add `tutor dev quickstart` command, which is equivalent to
`tutor local quickstart`, but uses dev containers instead
of local production ones and includes some other small
differences for the convience of Open edX developers.
This should remove some friction
from the Open edX development setup process, which previously
required that users provision using local producation
containers but then stop them and switch to dev containers:
* tutor local quickstart
* tutor local stop
* tutor dev start -d

Previously, it was possible to override settings by defining the
TUTOR_EDX_PLATFORM_SETTINGS environment variable. But let's face it:
- It was not very well supported.
- It was poorly explained.
- It was not very useful.
- It causes unnecessary code complexity.
For these reasons, we drop that feature.
- 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.
Close #545.
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.
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`.
It should be unnecessary to build a custom openedx-dev Docker image. All tests
can run from within the dev Docker image, with a couple additional environment
variables.
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.
First, allow using custom Django settings on a development
environment (as documented but not implemented), setting it to the
correct value of `tutor.development`. Prior to this, `tutor dev
runserver lms` would default to `tutor.production` when on a custom edX
branch.
Second, fix the documentation so the correct environment variable is
described, at the same time removing an option that doesn't seem to work.
See discussion: https://discuss.overhang.io/t/koa-dev-lms-doesnt-find-static-content/1250
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.

As suggested in [this topic](https://discuss.overhang.io/t/issue-with-paver-update-assets/641) I had to run `npm install` to get the packages it tries to copy from. That makes sense, so I think it should be part of the instructions here.
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
