Core Workflows

1. List Organizations

Use DOCKER_HUB_LIST_ORGANIZATIONS to discover which organizations the authenticated user belongs to.

Tool: DOCKER_HUB_LIST_ORGANIZATIONS Inputs:

• page: integer (1-indexed, default 1)
• page_size: integer (1-100, default 25)

2. Create an Organization

Use DOCKER_HUB_CREATE_ORGANIZATION to programmatically create a new Docker Hub organization.

Tool: DOCKER_HUB_CREATE_ORGANIZATION Inputs:

• orgname: string (required) -- lowercase, letters/numbers/._- only, min 2 chars
• company: string (optional) -- company name associated with the org

Note: Requires JWT authentication obtained via /v2/users/login and may have restricted access.

3. Get Organization Details and Repositories

Use DOCKER_HUB_GET_ORGANIZATION to retrieve namespace info and its repositories. Works with any public namespace.

Tool: DOCKER_HUB_GET_ORGANIZATION Inputs:

• organization: string (required) -- e.g., "docker", "bitnami", "library"

4. Create a Repository

Use DOCKER_HUB_CREATE_REPOSITORY to create public or private repositories under a namespace.

Tool: DOCKER_HUB_CREATE_REPOSITORY Inputs:

• namespace: string (required) -- Docker Hub username or org name
• name: string (required) -- lowercase; letters, numbers, ._- allowed
• description: string (optional) -- max 100 characters
• full_description: string (optional) -- Markdown README content
• is_private: boolean (default false) -- private repos require paid plan

5. List Repositories with Filtering

Use DOCKER_HUB_LIST_REPOSITORIES to enumerate repos within a namespace with sorting and content-type filtering.

Tool: DOCKER_HUB_LIST_REPOSITORIES Inputs:

• namespace: string (required) -- e.g., "library", "myorg"
• ordering: "name" | "last_updated" | "pull_count" (prefix with - for descending)
• page: integer (default 1)
• page_size: integer (1-100, default 25)
• content_types: string (comma-separated, e.g., "image,artifact")

6. Manage Teams, Members, and Webhooks

Use DOCKER_HUB_LIST_TEAMS to list teams within an org, DOCKER_HUB_ADD_ORG_MEMBER to invite users, and DOCKER_HUB_CREATE_WEBHOOK for push notifications.

Tool: DOCKER_HUB_LIST_TEAMS

• Lists all teams/groups within a Docker Hub organization

Tool: DOCKER_HUB_ADD_ORG_MEMBER

• Invite a user to join an organization by Docker ID or email
