Overview

This node interacts with Kubernetes clusters, specifically supporting operations on Deployments such as executing commands inside a pod. It is useful for automating Kubernetes management tasks like running commands within deployment pods, managing deployment lifecycle, and retrieving deployment information. For example, it can execute a shell command inside a pod of a deployment to troubleshoot or configure the application dynamically.

Use Case Examples

1. Executing a command inside a pod of a deployment to check application status or logs.
2. Restarting a deployment by running a specific command or patching deployment configuration.
3. Listing deployments in a specific namespace for monitoring or auditing purposes.

Properties

Output

JSON

• stdout - The standard output from executing a command inside the deployment's 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' property must be a JSON array; otherwise, an error 'Command must be an array!' is thrown. Validate the command input format before execution.
