Hello Cloud Native, Hello Kubernetes

Examples:
  # Apply the configuration in pod.json to a pod
  kubectl apply -f ./pod.json

  # Apply resources from a directory containing kustomization.yaml - e.g. dir/kustomization.yaml
  kubectl apply -k dir/

  # Apply the JSON passed into stdin to a pod
  cat pod.json | kubectl apply -f -

  # Apply the configuration from all files that end with '.json'
  kubectl apply -f '*.json'

  # Note: --prune is still in Alpha
  # Apply the configuration in manifest.yaml that matches label app=nginx and delete all other resources that are not in
the file and match label app=nginx
  kubectl apply --prune -f manifest.yaml -l app=nginx

  # Apply the configuration in manifest.yaml and delete all the other config maps that are not in the file
  kubectl apply --prune -f manifest.yaml --all --prune-allowlist=core/v1/ConfigMap
