Minikube started after updrade Docker version to 19.03.8.

[medyagh]

That is very interesting,

creating host: create: creating: prepare kic ssh: copying pub key: docker copy /tmp/tmpf-memory-asset852410486 into minikube:/home/docker/.ssh/authorized_keys, output: unknown shorthand flag: 'a' in -a
See 'docker cp --help'.

seems like docker command we were trying to run didn't exist

@porytskyi do you mind sharing
full output of
"docker version"

and what was your docker version before?

[medyagh]

@porytskyi do you mind also sharing

docker cp --help

[afbjorklund]

Same as #9075 - related to #9077

[medyagh]

could we try docker cp without -a ? it fails?

[tstromberg]

minikube started after updrade Docker version to 19.03.8 - I wonder what version was running before.

I'll note the -a flag does not exist in docker.io_1.13.1-0ubuntu6_amd64. It does seem like a very useful flag though. At a minimum this could use an actionable error message to ask for an upgrade.

The previous version was docker-ce 18.06.0 ~ ce ~ 3-0 ~ debian.
More information here: https://docs.docker.com/engine/install/debian in the Install Docker Engine section, step 2.

Please note that I am using Docker version 19.03.8. Everything is working now.

Usage:	docker cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH|-
	docker cp [OPTIONS] SRC_PATH|- CONTAINER:DEST_PATH

Copy files/folders between a container and the local filesystem

Use '-' as the source to read a tar archive from stdin
and extract it to a directory destination in a container.
Use '-' as the destination to stream a tar archive of a
container source to stdout.

Options:
  -a, --archive       Archive mode (copy all uid/gid information)
  -L, --follow-link   Always follow symbol link in SRC_PATH

Going to close this issue. The minimum supported docker version is 18.9 and it does have -a arg for cp command
