Bring Docker Hub tag details into issue follow-up
When a new issue comment raises an image question, ask Notis to retrieve the tag details your team needs for follow-up.
Trigger
New GitHub Issue Comment
Triggers when a new comment is added to a specific GitHub issue. Only genuinely new comments are emitted; edits to existing comments do not produce duplicate events. The payload includes the comment ID, text body, author details, timestamps, and direct links to the comment on GitHub.
Action
Get Docker Hub Tag
Tool to retrieve details of a specific Docker Hub repository tag. Use after confirming the namespace, repository, and tag name.
Why this helps
A comment can restart a thread of investigation when registry details are not close to the conversation.
- Keep tag context close to new issue discussion.
- Reduce repeated manual lookups during follow-up.
- Use a defined tag and repository for the request.
Setup
Build it in a few focused steps.
- 1Connect GitHub and Docker Hub once in the Notis portal.
- 2Create an automation from Automations, New Automation, or describe it to Notis from any channel.
- 3Describe in one instruction which Docker Hub namespace, repository and tag to retrieve after a new comment.
- 4Pick New GitHub Issue Comment as the trigger and choose where run reports go.
- 5Test with one real comment and confirm the right tag is requested.
Questions about this workflow
Does this trigger on edited comments?
No. The listed event emits genuinely new comments; edits to existing comments do not produce duplicate events.
Does it read a tag from the comment automatically?
Only if the comment payload provides it in usable context. Include the namespace, repository and tag in your instruction when needed.
