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.
