|
Lists Kubernetes running pods with labels matching key=value pair arguments, returning one pod name per line (convenient for shell piping)
|
|
|
|
All arguments after the first dash prefixed argument are treated as options to kubectl. This is where you should specify -n <namespace> or --all-namespaces
|
|
|
|
|
|
Requires kubectl to be installed and configured
