Overview

This node interacts with Kubernetes services, specifically executing commands inside containers of Kubernetes services. It is useful for running commands directly within a container of a service in a Kubernetes cluster, such as debugging, configuration, or maintenance tasks. For example, you can execute shell commands inside a container to inspect logs, modify files, or run scripts without needing to SSH into the host machine.

Use Case Examples

1. Executing a shell command inside a container of a Kubernetes service to check the status of an application.
2. Running a script inside a container to update configuration or environment variables dynamically.

Properties

Output

JSON

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

Dependencies

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

Troubleshooting

• Ensure Kubernetes credentials are correctly configured and accessible; otherwise, the node will throw a 'No credentials got returned!' error.
• The 'Resource Name' parameter is mandatory for the exec operation; missing it will cause an error.
• The 'command' parameter must be a valid JSON array; otherwise, the node will throw a 'Command must be an array!' error.
• If the container name is incorrect or the container does not exist in the service, the exec command will fail.
