The codebase at https://ops.gitlab.net/gitlab-com/gl-infra/sre-oncall-handover-automation/ should be moved to Woodhouse. A large portion of the logic already exists in https://gitlab.com/gitlab-com/gl-infra/oncall-robot-assistant, which is stubbed for migration here - https://gitlab.com/gitlab-com/gl-infra/infrastructure/-/issues/11776. --- The incoming/outgoing Engineers On-Call (EOCs) rely on the [`/sre-oncall`](https://ops.gitlab.net/gitlab-com/gl-infra/sre-oncall-handover-automation/) slash command to semi-automatically create an incident before a shift change. Rather than require a human run the command, we can easily leverage the PagerDuty schedule to detect a shift change (or use the set schedule of every 8 hours) to lookup the incoming/outgoing EOCs and create the issue. To do so, we'll need to maintain a map of SREs Slack and PagerDuty user IDs. ~~If this hasn't already been done in the old codebase, we should ensure that SREs who have already finished their shift can still create a handover issue. We could use a slash-command parameter or a modal to allow SREs to override the current shift and choose a previous shift.~~ ## Definition of Done - [x] the issue creation is automatically created 1-hour before shift change - [x] the incoming and outgoing on-call engineers are assigned the issue - [x] a reminder message with a link to the handover 1-hour before the shift-change is sent via direct message to both the incoming and outgoing EOCs - [x] a "shift-change" notification is posted to the `#incident-management` room at the handover time with a link to the issue - [x] the `/sre-oncall` slash command is deprecated - [x] the Slack/GitLab integration with the "On Call Handover" app is deprecated
