Verify a Docker image from a webhook
Give external release systems a direct path to Docker image verification through Notis.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Get Docker Hub Image
Tool to retrieve detailed information about a specific image within a Docker Hub repository. Use after confirming namespace, repository name, and image ID. Example: GET_IMAGE(namespace="library", repository="ubuntu", image_id="sha256:...")
Why this helps
External systems often need registry verification but lack a simple workflow for returning the result.
- Connects release systems to registry checks
- Returns image details quickly
- Reduces manual verification steps
Setup
Build it in a few focused steps.
- 1Connect Docker Hub to Notis once.
- 2Create an automation named Webhook Image Verification.
- 3Tell Notis to read image coordinates from the incoming webhook and retrieve the matching Docker Hub image details.
- 4Choose a Notis webhook trigger and select where run reports should go.
- 5Send one test webhook with a real image reference.
Questions about this workflow
What must the webhook include?
It should include enough information to identify the Docker Hub namespace, repository, and image ID.
Can it verify multiple images?
Yes, if the webhook payload clearly identifies each image.
