Overview

This node interacts with Kubernetes clusters, specifically supporting operations on various Kubernetes resources such as namespaces, pods, services, deployments, and more. The 'Exec' operation allows executing commands inside a pod within a specified namespace. This is useful for running scripts, debugging, or managing containerized applications directly from the workflow. For example, you can execute a shell command inside a pod to check logs or modify configurations dynamically.

Use Case Examples

  1. Executing a command inside a pod to retrieve application logs.
  2. Running a script inside a container to perform maintenance tasks.

Properties

Name Meaning
Image The container image to use when running or executing commands in a pod.
Namespace The Kubernetes namespace where the target resource (e.g., pod) resides.
Resource Name The name of the specific Kubernetes resource (e.g., pod) to target for the operation.

Output

JSON

  • stdout - The standard output resulting from executing the command inside the pod.

Dependencies

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

Troubleshooting

  • If no credentials are provided or invalid, the node throws an error 'No credentials got returned!'. Ensure valid Kubernetes API credentials are configured.
  • The 'command' input must be a JSON array; otherwise, an error 'Command must be an array!' is thrown. Validate the command format before execution.
