Overview
kubectl is the main Kubernetes command line tool, used to send REST API requests with JSON-formatted payloads into the API server.
Configuration
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.
Output in YAML Format
kubectl get -o yaml ...
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.
