Release process

Impact:

Changelog:

PR release workflow (internal)

• PR has internal ticket
• internal issue ID (PL-…) part of branch name
• internal issue ID mentioned in PR description text
• ticket is on Platform agile board
• ticket state set to Pull request ready
• if ticket is more urgent than within the next few days, directly contact a member of the Platform team

Design notes

• Provide a feature toggle if the change might need to be adjusted/reverted quickly depending on context. Consider whether the default should be on or off. Example: rate limiting.
• All customer-facing features and (NixOS) options need to be discoverable from documentation. Add or update relevant documentation such that hosted and guided customers can understand it as well.

Security implications

• Security requirements defined? (WHERE)
  • This should make incoming mail on gitlab more reliable, so problems like the one in the ticket don't occur.
• Security requirements tested? (EVIDENCE)
  • ran the gitlab test locally, with a slightly modified config to activate the gitlab-mailroom service
  • verified that it was restarted multiple times
