Axim engineers can deploy “sandbox” Open edX sites on certain pull requests in the openedx GitHub organization in order help test changes. These sandboxes are managed by OpenCraft using the Grove PR watcher.

Getting a sandbox on a PR
This guide is for Axim engineers. If you’re a contributor and you’d like to use this system for your PR, talk to your Axim POC (for funded contributions) or file an Axim request (all others). If we have the capacity, we may be able to set you up with one.
Prerequisite: The PR’s target repository must be
openedx/edx-platform
oropenedx/frontend-app-*
The PR author can be anyone.
Ensure that the target repository has the
pr-sandboxes-enabled
topic. Anyone with admin access to the repo can edit topics by going to the repo home page and clicking the gear next to “About”:Optionally, add a
**Settings**
and/or**Tutor Requirements**
section to the PR’s description in order to customize the sandbox. Details here.Add the
create-sandbox
label to the PRWait 30 minutes. One of three things should happen:
open-craft-grove will tell you “Sandbox deployment successful 🚀 “
open-craft-grove will tell you “Sandbox deployment failed 💥 “
Check out the linked Grove logs-- they may or may not help you figure out the problem. Unfortunately, the app logs are not available to us.
nothing
In case (b) or (c), join the #grove-pr-watcher Slack channel and ping Kaustav with a link to the PR.
Notes on sandbox behavior
The admin username is
openedx
and the password is the same. If you want to secure your sandbox’s data against public access, then change the admin password. You should also be able to create unprivileged user accounts as necessary.The sandbox will redeploy every ~15 minutes if either of the following conditions are met:
The PR’s latest commit hash has changed
The PR’s Settings or Tutor Requirements sections have changed
The sandbox will be destroyed after ~15 minutes if either of the following conditions are met:
The create-sandbox label has been removed
The PR is merged or closed
When the sandbox redeploys, its database is preserved. To fully destroy and recreate with a fresh db, you will need a workaround:
Remove the create-sandbox label
Wait ~15 minutes
Check that the sandbox has been destroyed by going to the LMS. You should see a message like “This site is being provisioned”.
Put the create-sandbox label back
Idle sandboxes will be destroyed after weeks of inactivity. You can bring them back to life by pushing a new commit or rebasing your PR.
We have a usage budget for about 30 running instances. OpenCraft will let us know if we’re bumping up against that.
PRs to master/main will use Tutor Nightly. PRs to named release branches will use the latest patch release of the corresponding Tutor version (e.g., Quince →
tutor>=17,<18
). The Tutor version can be overridden using the Tutor Requirements section, as explained in the docs.
Known issues & wishes
Axim engineers, as you encounter things about the sandboxes that you wish could be improved, add them here. For items that seem like bugs, also ping in #grove-pr-watcher.
Access to application logs
Status of sandbox build
At a minimum: Always-fail-loudly. That is, “nothing” should never happen, there should always be a comment when the build fails for any reason.
Note: We used to have comments for this, but turned them off because they were too noisy. Would there be a less noisy way ot notifying?
Idea: Use the GitHub checks system rather than bot comments
Idea: Configurable notification levels
Idea: One comment updated with status over time

Ability to fully destroy and recreate the sandbox without using the remove-label-wait-and-put-it-back workaround described above.
Ability to force a redeploy without pushing a commit. This can be desirable when a change is pushed to a dependency other than the PR itself (e.g. a Tutor branch).

Note: you can kinda get at this by filtering on the create-sandbox label
