Look up a Docker Hub tag mentioned in a Linear comment
Keep a request to inspect a tag from turning into another search someone has to remember.
Trigger
Comment Received Trigger
Triggered when a comment is received.
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
Tag details are scattered across Docker Hub and Linear, slowing down small but important investigations.
- Respond to explicit requests in the issue discussion.
- Reduce context switching during image investigation.
- Keep the requested tag connected to its issue context.
Setup
Build it in a few focused steps.
- 1Connect Linear and Docker Hub to Notis once through the portal.
- 2Create an automation and instruct Notis to retrieve tag details when a Linear comment asks to inspect a Docker Hub tag and identifies its repository.
- 3Choose the Linear Comment Received trigger.
- 4Choose a channel for run reports and test with a comment naming one repository and tag.
Questions about this workflow
What kind of comments should trigger the lookup?
The prompt should specify that the comment must request a tag inspection and identify the intended repository and tag.
Does the action change the tag?
No. This workflow retrieves tag details and does not modify Docker Hub.
