Check the Docker Hub repository list after a metric change
Use a meaningful release metric change as a cue to review the repositories in a Docker Hub namespace.
Trigger
Aggregate Metric Changed
Triggers when an aggregate metric (SUM/COUNT/AVG/MIN/MAX) changes in a Google Sheets spreadsheet. This trigger monitors an aggregate calculation on a target column (optionally filtered by a search column/value) and fires when the calculated result changes.
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
A changing release count may call for a quick inventory, but repository checks often mean leaving the tracker and remembering the namespace.
- Tie repository inventory checks to a tracked aggregate change.
- Get repository data in the same workflow report.
- Spend less time switching between a metric sheet and Docker Hub.
Setup
Build it in a few focused steps.
- 1Connect Google Sheets and Docker Hub once in the Notis portal.
- 2Create an automation in Automations, then New Automation, and give it a name.
- 3Tell Notis to list repositories in the named Docker Hub namespace and summarize the result when the tracked metric changes.
- 4Pick Aggregate Metric Changed as the trigger and choose where run reports should go.
- 5Test with one real metric change and confirm the namespace is included in the instruction.
Questions about this workflow
Can the workflow tell me which repositories are ready to release?
The action lists repositories. Any readiness criteria must be provided in the instruction and supported by returned data.
What happens if the metric changes for an unrelated reason?
The trigger fires when the monitored aggregate changes. Describe in your instruction how Notis should handle the resulting event.

Aggregate Metric Changed
Triggers when an aggregate metric (SUM/COUNT/AVG/MIN/MAX) changes in a Google Sheets spreadsheet. This trigger monitors an aggregate calculation on a target column (optionally filtered by a search column/value) and fires when the calculated result changes.
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.
Cell Range Values Changed
Triggers when values in a specified A1 range change in Google Sheets. This trigger monitors a specific cell or range of cells and fires when any values change.
Create Docker Hub Webhook
Tool to create a webhook on a Docker Hub repository. Use after determining repository details.
Conditional Format Rule Changed
Triggers when conditional formatting rules change in a Google Spreadsheet. Detects when rules are added, updated, or removed. Uses snapshot-based diffing to detect changes between polls.
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.
Data Validation Rule Changed
Triggers when data validation rules change (added/updated/removed) in a Google Spreadsheet. Uses snapshot-based diffing to detect changes between polls.
Delete Docker Hub Organization
Tool to delete a specific Docker Hub organization. Use when you need to permanently remove an organization. Deletion is irreversible.
Developer Metadata Changed
Triggers when developer metadata entries change (new/updated/removed) in a Google Spreadsheet. Uses snapshot-based diffing to detect changes between polls.
Delete Docker Hub Repository
Tool to delete a specific Docker Hub repository. Use when you need to permanently remove a repository. Deletion is irreversible.
Filtered Range Values Changed
Polling trigger that monitors Google Sheets filtered ranges for value changes. Uses snapshot-based diffing to detect when values matching a data filter change. Emits the matched values when changes are detected.
Delete Repository Tag
Tool to delete a specific tag from a Docker Hub repository. Use after confirming the tag to remove.
