Review repository tags after a release cancellation
A canceled release meeting can trigger a quick tag review to help your team regroup.
Trigger
Event Canceled or Deleted
Triggers when a Google Calendar event is cancelled or deleted. Returns minimal data: event_id, summary (if available), and cancellation timestamp.
Action
List Repository Tags
Tool to list tags for a Docker Hub repository. Use after specifying namespace and repository.
Why this helps
When a release event disappears from the calendar, related repository follow-up can disappear from view too.
- Use a cancellation as a prompt to review current repository tags.
- Keep the repository details explicit in your instruction.
- Send the lookup result to your selected report channel.
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and Docker Hub once in the Notis portal.
- 2Create an automation and give it a name and report channel.
- 3Tell Notis to list tags for your specified release repository when a matching event is canceled.
- 4Pick the Google Calendar Event Canceled or Deleted trigger.
- 5Choose where run reports go, then test with one real cancellation event.
Questions about this workflow
Can the cancellation event identify the repository?
The trigger returns minimal event data. Provide the repository and namespace in your instruction unless that information is available elsewhere to Notis.
Does this remove tags or images?
No. It only lists tags for review.
