Turn release setup requests into Docker Hub webhooks
When someone asks for a repository webhook in Slack, Notis can create it in Docker Hub so release events are ready for the next step.
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
Create Docker Hub Webhook
Tool to create a webhook on a Docker Hub repository. Use after determining repository details.
Why this helps
Webhook requests can disappear in busy release channels while setup waits for someone to revisit them.
- Captures webhook requests at the point they are made.
- Cuts repeated navigation during release preparation.
- Makes notification setup part of a visible team conversation.
Setup
Build it in a few focused steps.
- 1Connect Slack and Docker Hub to Notis once in the portal.
- 2Create an automation with a plain-language instruction to create a Docker Hub webhook when a channel message clearly requests one and contains the repository and destination details.
- 3Select Channel Message Received as the trigger and choose a run-report channel.
- 4Test with a real, clearly specified webhook request and verify the Docker Hub webhook.
Questions about this workflow
What if the message lacks webhook details?
Tell Notis in the instruction to skip incomplete requests and report what information is missing.
Will this act on every message?
Use a clear instruction that limits action to messages explicitly requesting a repository webhook.
