Answer Slack repository questions with Docker Hub data
Keep repository lookups in the conversation where the question was asked.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
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
Repository questions interrupt focused work when someone has to leave Slack and search Docker Hub manually.
- Answers repository questions in context
- Reduces tool switching
- Creates a repeatable lookup process
Setup
Build it in a few focused steps.
- 1Connect Slackbot and Docker Hub once in Notis.
- 2Create an automation named Channel repository inventory.
- 3Tell Notis to list repositories for the namespace mentioned in the Slack request and summarize the results.
- 4Pick Slack channel message received as the trigger and choose where run reports go.
- 5Test it with one real repository question.
