| + | 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). | ||
