kubectl cp --help
Copy files and directories to and from containers.
Examples:
# !!!Important Note!!!
# Requires that the 'tar' binary is present in your container
# image. If 'tar' is not present, 'kubectl cp' will fail.
#
# For advanced use cases, such as symlinks, wildcard expansion or
# 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>
kubectl cp /tmp/foo <some-namespace>/<some-pod>:/tmp/bar
# Copy /tmp/foo from a remote pod to /tmp/bar locally
kubectl cp <some-namespace>/<some-pod>:/tmp/foo /tmp/bar
Options:
-c, --container='':
Container name. If omitted, use the kubectl.kubernetes.io/default-container annotation for
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
--retries=0:
Set number of retries to complete a copy operation from a container. Specify 0 to disable
or any negative value for infinite retrying. The default is 0 (no retry).
Usage:
kubectl cp <file-spec-src> <file-spec-dest> [options]
Use "kubectl options" for a list of global command-line options (applies to all commands).
