Containerd: Copying files from containerd container to host

Question

I am looking for equivalent of docker cp command in containerd.

For example what will be the equivalent of below in containerd

docker cp <container-id>:<path> <host-path>

ex: docker cp ed128ed:/etc/file1 file1

Answer 1

There are no features same as docker cp on containerd, but you can use the command ctr snapshot mounts which mounts the container's root to the host path.

mkdir /tmp/containerfiles
ctr snapshot mounts /tmp/containerfiles {container_id}

Then you can copy any contents of the container from /tmp/containerfiles.
