Overview

This node interacts with Kubernetes clusters, specifically performing a port forwarding operation on StatefulSets in this context. It allows users to forward one or more local ports to a pod in a StatefulSet, enabling access to the pod's network services from the local machine. This is useful for debugging, monitoring, or accessing applications running inside the Kubernetes cluster without exposing them externally.

Use Case Examples

1. Forward a local port to a StatefulSet pod to access a database service running inside the cluster.
2. Use port forwarding to connect to an internal web application hosted in a StatefulSet for testing purposes.

Output

JSON

• json - The result of the port forwarding operation, typically connection details or status information.

Dependencies

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

Troubleshooting

• Ensure Kubernetes credentials are correctly configured and have sufficient permissions to perform port forwarding.
• Verify the StatefulSet resource name is provided; it is required for the port forwarding operation.
• Common errors include missing resource name or insufficient permissions, which can be resolved by providing the correct resource name and updating credentials or RBAC settings.
