Retrieve Docker image details from review comments
Keep the discussion and the image under review close together.
Trigger
Comment Created
Triggers when a new comment is created in Notion. Optional `page_id` filter scopes to comments on a specific page. When omitted, fires for any new comment in the workspace the integration has access to. Requires the 'Read comments' capability on the Notion integration. If a connection was authorized before that capability was enabled, the user must re-authorize the connection for comment events to flow.
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
A reviewer asks about a container image, and someone has to leave the discussion to locate its details.
- Reduce interruptions during technical reviews.
- Give reviewers image context while the question is fresh.
- Make container discussions easier to continue.
Setup
Build it in a few focused steps.
- 1Connect Notion and Docker Hub to Notis once in the portal.
- 2Create an automation in the portal or ask Notis conversationally.
- 3In one prompt, ask Notis to use a new comment on the container review to identify and retrieve the referenced Docker image details, then summarize them in the run report.
- 4Select the Notion Comment Created trigger and scope it to the review page if appropriate; choose a reporting channel.
- 5Test with a real comment that names an image.
Questions about this workflow
Does every workspace comment trigger this?
You can scope the Comment Created trigger to a page when the review lives on a known page.
What if the comment does not identify an image?
The prompt can ask Notis to report that it could not confidently identify an image.

Supported Triggers and Actions
Notis builds workflows that link Notion to Docker hub. A trigger fires from one place; an action lands in another.
Notion 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.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
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.
Comment Created
Triggers when a new comment is created in Notion. Optional `page_id` filter scopes to comments on a specific page. When omitted, fires for any new comment in the workspace the integration has access to. Requires the 'Read comments' capability on the Notion integration. If a connection was authorized before that capability was enabled, the user must re-authorize the connection for comment events to flow.
Create Docker Hub Webhook
Tool to create a webhook on a Docker Hub repository. Use after determining repository details.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
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.
Database Created
Triggers when a new Notion database (the container) is created. A database is the post-2025-09-03 container that holds one or more data sources. This trigger fires for the container's creation event (`database.created`), distinct from `NOTION_DATASOURCE_CREATED` which fires when a new data source is added to an existing database. Most customers calling Notion's `POST /v1/databases` (the legacy API) or creating a database via the Notion UI will see this event. Adding a new data source to an existing database fires `data_source.created` instead — use `NOTION_DATASOURCE_CREATED` for that. Notion's payload puts `entity.type: "block"` (the container is a `child_database` block in the content tree) and `entity.id` is the database id.
Delete Docker Hub Organization
Tool to delete a specific Docker Hub organization. Use when you need to permanently remove an organization. Deletion is irreversible.
Data Source Created
Triggers when a new Notion data source is created. Fires workspace-wide. The payload's `data.parent` carries the data source's tree parent (typically the teamspace) for downstream filtering. A single template-based database creation can fire multiple `data_source.created` events at once — one per data source the template instantiates.
Delete Docker Hub Repository
Tool to delete a specific Docker Hub repository. Use when you need to permanently remove a repository. Deletion is irreversible.
Data Source Schema Updated
Triggers when a Notion data source's schema is updated. Fires on column add / remove / rename. Payload includes `data.updated_properties: [{id, name, action}]` so consumers can discriminate the kind of change downstream. Optional `data_source_id` filter scopes to schema changes on a single data source. When omitted, fires for any schema change in the workspace the integration has access to. Note: adding a column also fires `page.properties_updated` once per existing row in the data source. Customers wanting a single structural-change signal should use this trigger.
Delete Repository Tag
Tool to delete a specific tag from a Docker Hub repository. Use after confirming the tag to remove.
