Find an existing Docker Hub repository when container work starts
Check what already exists before adding another repository to the workload.
Trigger
Public Team Issue Created
Fires when a new issue is created in a Linear *public* team. For private teams (lock icon in Linear's sidebar) use `LINEAR_PRIVATE_TEAM_ISSUE_CREATED`.
Action
List Docker Hub Repositories
Tool to list repositories under a namespace. Use when you need to enumerate repositories within a specific Docker Hub namespace, with optional filtering and pagination.
Why this helps
Teams can create duplicate repository setup work because existing projects are hard to recall.
- Check for an existing repository before creating one.
- Reduce duplicate setup and naming decisions.
- Keep discovery connected to the issue that needs the container.
Setup
Build it in a few focused steps.
- 1Connect Linear and Docker Hub to Notis once through the portal.
- 2Tell Notis to list Docker Hub repositories in the namespace identified by a new public-team Linear issue about container work.
- 3Choose the Public Team Issue Created trigger.
- 4Choose a channel for run reports and test with an issue that names the namespace.
Questions about this workflow
Does this create a repository?
No. It lists repositories so the team can check whether a suitable one already exists.
What context should the issue include?
Identify the Docker Hub namespace and describe the container work so Notis can determine when a lookup is useful.
