Overview
This node executes Kubernetes or shell commands remotely by sending them to a specified remote API endpoint. It is useful for automating command execution on Kubernetes clusters or remote servers without direct access, by leveraging an API that runs the commands and returns the results. For example, it can be used to retrieve pod information or describe pod details in a Kubernetes environment via API calls.
Use Case Examples
- Running 'kubectl get pods' to list all pods in a cluster.
- Executing multiple commands separated by newlines to perform batch operations remotely.

Dependencies

Troubleshooting
- If no commands are provided, the node throws an error indicating no valid shell commands were found.
- If the remote API URL is incorrect or unreachable, the node throws an error with the message from the failed request.
- Timeouts may occur if the remote API does not respond within 25 seconds, resulting in an error.
