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
  - Requires owner or admin permissions

Tool: DOCKER_HUB_CREATE_WEBHOOK
  - Create a webhook on a repository for image push notifications
  - Two-step process: create webhook, then add hook URL
  - Requires admin permissions on the repository

Known Pitfalls

| Pitfall | Detail | |---------|--------| | JWT authentication | DOCKER_HUB_CREATE_ORGANIZATION requires JWT auth from /v2/users/login -- standard API tokens may not suffice. | | Private repo limits | Creating private repos (is_private: true) requires a paid Docker Hub plan. | | Org name constraints | Organization names must be lowercase, at least 2 characters, containing only letters, numbers, ., _, or -. | | Webhook two-step | DOCKER_HUB_CREATE_WEBHOOK is a two-step process: first create the webhook with a name, then add a hook URL to it. | | Pagination | All list endpoints use page-based pagination -- iterate pages until results are exhausted. |
