Usage:

multi-kubectl supports two flags

• --match-ctx for any match
• --ctx for the exact match

multi-kubectl get ns --match-ctx prod 

this will run kubectl get ns against all contexts, which name contains the string prod

multi-kubectl get ns --ctx kind-second --ctx=kind-kind

will get from namespaces using the contexts kind-kind and kind-second

multi-kubectl get ns --ctx=my-context

will get the namespaces using the context my-context

Requirements:

• kubectl
• configured KUBECONFIG

Examples:

❯ multi-kubectl get pods -A --match-ctx=kind
cluster:kind-kind
