Overview

kubectl is the main Kubernetes command line tool, used to send REST API requests with JSON-formatted payloads into the API server.

Configuration

.kube config

Commands

Options

Obtaining Information about API Objects

kubectl get
kubectl describe

kubectl get and kubectl describe mask sensitive information such as a secret's content to protect it from being exposed accidentally to an onlooker or from being stored in a terminal log.

POSTing a Manifest

kubectl apply -f filename.yaml

Get the Manifest for an Existing Object

The manifest can be used to recreate the object:

kubectl get pod pod-name --export -o yaml

Note that --export is deprecated and will be removed in the future so find an equivalent.
