Overview

This node interacts with Kubernetes services, specifically supporting the 'exec' operation among others. It allows executing commands inside a Kubernetes service container by specifying the service name, namespace, and command to run. This is useful for running administrative or diagnostic commands directly within a service's container environment, such as checking logs, running scripts, or debugging.

Use Case Examples

1. Executing a shell command inside a Kubernetes service container to check the status of the application.
2. Running a diagnostic command inside a service container to gather runtime information.

Properties

Output

JSON

• stdout - The standard output from the executed command inside the Kubernetes service container.

Dependencies

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

Troubleshooting

• Ensure that the Kubernetes credentials are correctly configured and accessible; otherwise, the node will throw a 'No credentials got returned!' error.
• The 'command' input must be a valid JSON array; if not, the node throws 'Command must be an array!' error.
• Verify that the specified namespace and service name exist in the Kubernetes cluster to avoid execution failures.
