Review image details when a GitHub deployment changes
When deployment details shift, bring the related image metadata into your review with a focused Docker Hub lookup.
Trigger
GitHub Deployment State Changed
Triggers when a specific GitHub deployment's fields change. Monitors the following aspects of a single deployment: - ``environment`` -- the target environment name - ``original_environment`` -- the original environment name before normalization - ``description`` -- the human-readable deployment description - ``task`` -- the deployment task name - ``sha`` -- the commit SHA being deployed - ``ref`` -- the branch, tag, or SHA reference being deployed - ``updated_at`` -- the last-updated timestamp - ``transient_environment`` -- whether the environment is temporary - ``production_environment`` -- whether this is a production deployment When any of these fields change, an event is emitted containing the full current deployment details and a list of which fields changed.
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
Deployment investigation slows when image details require a separate registry search after a deployment update.
- Keep image metadata near deployment changes.
- Reduce manual lookups while investigating deployment updates.
- Use a specific image ID to make the request actionable.
Setup
Build it in a few focused steps.
- 1Connect GitHub and Docker Hub once in the Notis portal.
- 2Create an automation in Automations, New Automation, or tell Notis from any channel.
- 3Describe in one instruction the Docker Hub namespace, repository and image ID to retrieve for deployment changes.
- 4Pick GitHub Deployment State Changed as the trigger and choose where run reports go.
- 5Test with one real deployment update and confirm the image identifier is available.
Questions about this workflow
Does the deployment event include a Docker image ID?
The event description does not guarantee one. Provide the namespace, repository and image ID or ensure those details are available to Notis.
Will this change deployment state?
No. The action retrieves Docker Hub image details and does not modify GitHub deployments.

Supported Triggers and Actions
Notis builds workflows that link GitHub to Docker hub. A trigger fires from one place; an action lands in another.
GitHub triggers
Docker hub actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Add Organization Member
Tool to send an invitation for a user to join a Docker Hub organization. Use when you need to grant membership by inviting a user via their username after choosing the appropriate role.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Create Docker Hub Organization
Tool to create a Docker Hub organization. Use when you need to programmatically instantiate a new namespace for organizing repositories.
New Workflow Artifact Created
Triggers when a new workflow artifact is created in a GitHub repository. Monitors for newly created GitHub Actions workflow artifacts. Optionally filters by artifact name to restrict monitoring to specific artifacts.
Create Docker Hub Repository
Tool to create a Docker Hub repository under a namespace. Use when you need to programmatically instantiate a new repo under your organization or user.
Branch Changed
Triggers when a GitHub branch changes. Monitors a specific branch for: - New commits pushed (head commit SHA changes) - Protection status toggled (branch becomes protected or unprotected) - Protection settings changed, including: required status checks and their enforcement level, admin enforcement, required pull request reviews (dismiss stale reviews, code owner reviews, approving review count, last push approval), required linear history, force push allowance, deletion allowance, conversation resolution, branch locking, and fork syncing.
Create Docker Hub Webhook
Tool to create a webhook on a Docker Hub repository. Use after determining repository details.
New Branch Created
Triggers when a new branch is created in a GitHub repository. Detects newly created branches. Deleted branches do not fire events.
Delete Repository Image
Tool to delete a specific image within a Docker Hub repository. Use when you have confirmed the namespace, repository, and image ID to remove.
Check Run Status / Conclusion Changed
Triggers when a specific GitHub check run changes its status or conclusion. Monitors a single check run for changes to: status (queued, in_progress, completed, etc.), conclusion (success, failure, neutral, cancelled, skipped, timed_out, action_required), started_at, and completed_at.
Delete Docker Hub Organization
Tool to delete a specific Docker Hub organization. Use when you need to permanently remove an organization. Deletion is irreversible.
Check Suite Status / Conclusion Changed
Triggers when a GitHub check suite changes its status or conclusion for a given ref. Monitors all check suites associated with a git reference (branch, tag, or commit SHA) for changes to status (queued, in_progress, completed, etc.) and conclusion (success, failure, neutral, cancelled, skipped, timed_out, action_required, startup_failure, stale). Optionally filters by GitHub App ID.
Delete Docker Hub Repository
Tool to delete a specific Docker Hub repository. Use when you need to permanently remove a repository. Deletion is irreversible.
New Code Scanning Alert Created
Triggers when a new code scanning alert is created in a repository. Fires an event for each newly created code scanning alert detected in the configured repository. Alerts can be filtered by Git reference, scanning tool, state, and severity. The payload includes the alert number, rule details, tool information, state, severity, and the location of the most recent instance.
Delete Repository Tag
Tool to delete a specific tag from a Docker Hub repository. Use after confirming the tag to remove.
