Check Docker Hub image variants after a GitHub tag is created
A new source control tag can be a cue to review registry image variants. Notis can list them for the Docker Hub repository you specify.
Trigger
New Repository Tag Created
Triggers when a new tag is created in a GitHub repository. Monitors the repository's tags and fires an event for each newly created tag. The payload includes the tag name, the commit SHA and URL it points to, and archive download URLs.
Action
List Repository Images
Tool to list image variants for a specific Docker Hub repository. Use after specifying namespace and repository.
Why this helps
Release checks can become scattered when you need to search Docker Hub for image variants after tagging code in GitHub.
- Bring image variant details into tag based release checks.
- Reduce manual navigation between GitHub and Docker Hub.
- Use a specified registry repository to keep the lookup grounded.
Setup
Build it in a few focused steps.
- 1Connect GitHub and Docker Hub once in the Notis portal.
- 2Create an automation through Automations, New Automation, or by telling Notis from any channel.
- 3In one instruction, ask Notis to list image variants for the Docker Hub repository associated with the new tag.
- 4Pick New Repository Tag Created as the trigger and choose where run reports go.
- 5Test with one real repository tag and verify the namespace and repository used.
Questions about this workflow
Will this push the GitHub tag to Docker Hub?
No. The listed action shows image variants for an existing Docker Hub repository; it does not publish or tag images.
What if the GitHub tag does not identify the Docker Hub repository?
Include the Docker Hub namespace and repository in your instruction so Notis has the information needed for the lookup.

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.
