Check Docker Hub tags after a release email
After you send release details, Notis can check the named repository's Docker Hub tags and return the current list for a quick follow-through.
Trigger
Email Sent
Triggers when a Gmail message is sent by the authenticated user. It polls the 'SENT' label and emits metadata including sender, recipients, subject, timestamp, and thread ID.
Action
List Repository Tags
Tool to list tags for a Docker Hub repository. Use after specifying namespace and repository.
Why this helps
Release communication and repository checks happen in separate places, making it easy to skip the final verification.
- Add a repository check to an existing release communication step.
- See the current tag list in the run report.
- Catch messages that do not name a namespace or repository.
Setup
Build it in a few focused steps.
- 1Connect Gmail and Docker Hub once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name and prompt.
- 3Tell Notis to list tags only after a sent release email clearly identifies the Docker Hub namespace and repository, then summarize the returned tags.
- 4Pick Email Sent as the trigger and choose where run reports go.
- 5Test with one real sent release email.
Questions about this workflow
Does the action verify that a particular tag was published?
The action lists repository tags. Your prompt can ask Notis to check whether a named tag appears in that returned list.
What if the sent email mentions multiple repositories?
Specify in the prompt how to handle multiple clearly named repositories, or have Notis report the ambiguity.
