Overview

This node operation allows users to create a new container registry within a specified project. It is useful for managing container image repositories by programmatically adding registries where container images can be stored and accessed. Typical use cases include automating the setup of container registries in cloud projects or integrating container management workflows into CI/CD pipelines.

For example, a DevOps engineer might use this node to automatically create a Docker registry in a project when provisioning infrastructure, enabling seamless deployment of containerized applications.

Properties

Name Meaning
Project Id The unique identifier of the project under which the container registry will be created.
Credentials JSON object containing authentication details with username and password fields.
Description A textual description of the registry, e.g., "DockerHub".
Uri The URI of the container registry, e.g., "index.docker.io".

Output

The node outputs JSON data representing the response from the API after creating the container registry. This typically includes details about the newly created registry such as its ID, URI, description, and possibly status or metadata confirming successful creation.

No binary data output is indicated.

Dependencies

  • Requires an API key credential for authenticating requests to the mittwald mStudio API.
  • The node uses the mittwald mStudio API endpoint at https://api.mittwald.de.
  • Proper configuration of the API credentials in n8n is necessary for successful execution.

Troubleshooting

  • Authentication errors: Ensure that the API key credential is correctly configured and has sufficient permissions to create container registries.
  • Invalid project ID: Verify that the provided Project Id exists and is accessible by the authenticated user.
  • Malformed credentials JSON: The Credentials property must be a valid JSON string containing both username and password.
  • API connectivity issues: Check network access to https://api.mittwald.de and confirm no firewall or proxy blocks the request.

Common error messages may include unauthorized access, invalid input data, or server errors. Reviewing the API response message usually helps identify the root cause.
