−
  # file mode preservation, consider using 'kubectl exec'.
 
−
 
−
  # Copy /tmp/foo local file to /tmp/bar in a remote pod in namespace <some-namespace>
 
−
  tar cf - /tmp/foo | kubectl exec -i -n <some-namespace> <some-pod> -- tar xf - -C /tmp/bar
 
−
 
−
  # Copy /tmp/foo from a remote pod to /tmp/bar locally
 
−
  kubectl exec -n <some-namespace> <some-pod> -- tar cf - /tmp/foo | tar xf - -C /tmp/bar
 
−
 
−
  # Copy /tmp/foo_dir local directory to /tmp/bar_dir in a remote pod in the default namespace
 
−
  kubectl cp /tmp/foo_dir <some-pod>:/tmp/bar_dir
 
−
 
−
  # Copy /tmp/foo local file to /tmp/bar in a remote pod in a specific container
 
−
  kubectl cp /tmp/foo <some-pod>:/tmp/bar -c <specific-container>

−
  # Copy /tmp/foo local file to /tmp/bar in a remote pod in namespace <some-namespace>

        selecting the container to be attached or the first container in the pod will be chosen
 
−
 
−
    --no-preserve=false:
 
−
        The copied file/directory's ownership and permissions will not be preserved in the
 
−
        container
