mittwald

Overview

This node operation updates an existing container registry configuration in the mittwald mStudio API. It allows users to modify details such as the registry's URI, description, and authentication credentials. This is useful when you need to change access credentials or update metadata for a container registry that your workflows interact with.

Practical examples include:

• Updating the password or username used to authenticate against a Docker registry.
• Changing the registry URL if the registry endpoint has moved.
• Modifying the description to better reflect the purpose or environment of the registry.

Properties

Output

The node outputs JSON data representing the response from the mittwald mStudio API after updating the container registry. This typically includes confirmation of the update and the current state of the registry resource.

No binary data output is indicated.

Dependencies

• Requires an API key credential for the mittwald mStudio API.
• The node communicates with the mittwald mStudio API at https://api.mittwald.de.
• Proper network connectivity and valid credentials are necessary for successful operation.

Troubleshooting

• Invalid Registry Id: If the provided Registry Id does not exist, the API will likely return an error indicating the resource was not found. Verify the Registry Id before running the node.
• Authentication Errors: Incorrect username or password in the credentials property may cause authentication failures. Ensure credentials are correct and properly formatted as JSON.
• API Connectivity Issues: Network problems or incorrect base URL configuration can prevent the node from reaching the API. Confirm internet access and API endpoint correctness.
• Malformed JSON in Credentials: Since credentials are expected as a JSON string, invalid JSON formatting will cause errors. Use proper JSON syntax.
