Overview

This node interacts with Kubernetes to run a pod with a specified container image and command, then retrieves the output from the pod's execution. It is useful for automating containerized tasks within a Kubernetes cluster, such as running batch jobs or executing scripts inside a container environment. For example, you can use it to run a data processing script inside a container and capture the output for further workflow steps.

Use Case Examples

1. Run a pod with a specific Docker image and command to process data and return the results.
2. Execute a containerized script in a Kubernetes cluster and capture its output for logging or decision-making.

Properties

Output

JSON

• stdout - The standard output from the executed pod command.

Dependencies

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

Troubleshooting

• Ensure the 'Command' property is a valid JSON array; otherwise, the node will throw an error 'Command must be an array!'.
• Verify that Kubernetes credentials are correctly configured; missing credentials will cause the error 'No credentials got returned!'.
• Make sure the specified container image is accessible and valid in the Kubernetes environment.
• Check that the namespace and resource names are correct and exist in the Kubernetes cluster to avoid resource not found errors.
