Execute a command in a kubernetes pod¤
Python Plugin
This operator is part of a Python Plugin Package. In order to use it, you need to install it, e.g. with cmemc.
This plugin enables execution of commands inside Kubernetes pods and captures their output.
Features¤
- Supports multiple connection types:
- In-cluster: Uses the service account kubernetes gives to pods (for plugins running inside k8s)
- Explicit config: Uses a YAML kubeconfig file for external connections
- Executes shell commands in specified pods within namespaces
- Captures both stdout and stderr output
- Returns command output as a file entity for further processing
- Includes namespace listing functionality to verify cluster access and connectivity
Output¤
Command output is captured and returned as a text file entity that can be consumed by downstream workflow tasks.
Use Cases¤
- Running external pipelines
- Running diagnostic commands in production pods
- Executing maintenance scripts from within or outside the cluster
- Gathering system information and logs
- Performing health checks and troubleshooting
