Script Execution

Wake can run scripts in Kubernetes pods and collect the output. This feature is useful for debugging, maintenance, or any task that requires executing commands in the pod's environment.

Script Execution UI

Syntax​

wake --script-in <path-to-script.sh> [--namespace <ns>] [--pod-selector <regex>] [--script-outdir <dir>]
  • --script-in <path-to-script.sh>: Path to the script file to be executed in the pods.
  • --namespace <ns>: (Optional) Kubernetes namespace. Default is default.
  • --pod-selector <regex>: (Optional) Regex to select pods. Default is all pods.
  • --script-outdir <dir>: (Optional) Directory to save script output.

Output Files​

For each pod, the output will be saved as:

  • <namespace>_<pod>.stdout.txt: Standard output of the script.
  • <namespace>_<pod>.stderr.txt: Standard error of the script.

These files are saved in a directory named like wake_output_YYYYMMDD_HHMMSS/ by default.

Example​

wake --script-in ./dummy_script.sh --namespace apps --pod-selector 'nginx.*' --script-outdir ./results

This command runs dummy_script.sh in all pods in the apps namespace that match the nginx.* regex, and saves the output in the ./results directory.
