Overview

This node interacts with Kubernetes clusters, allowing users to perform various operations on Kubernetes resources. Specifically, for the 'Deployments' resource with the 'List' operation, it retrieves a list of deployments within a specified namespace. This is useful for monitoring and managing deployments in a Kubernetes environment, such as listing all deployments in the 'default' namespace or any other specified namespace.

Use Case Examples

1. List all deployments in the 'default' namespace to monitor active deployments.
2. Retrieve deployments in a specific namespace to manage application versions and scaling.

Properties

Output

JSON

• deployments - An array of deployment objects retrieved from the Kubernetes cluster.

Dependencies

• Requires Kubernetes API credentials to authenticate and interact with the Kubernetes cluster.

Troubleshooting

• Ensure Kubernetes credentials are correctly configured and accessible; missing credentials will cause the node to throw an error.
• Verify that the specified namespace exists in the Kubernetes cluster; an invalid namespace may result in empty or error responses.
• If the resource name is specified, ensure it matches an existing deployment; otherwise, the list operation may return no results or errors.
