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.
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
The `dev` commands now rely on a different openedx-dev docker image.
This gives us multiple improvements:
- no more chown in base image
- faster chown in development
- mounted requirements volume in development
- fix static assets issues
- bundled ipdb/vim/... packages, which are convenient for development
Close #235
