My kubectl cp isnt working due to tar not being in my bin folder of my container. I can't seem to find how to get it installed.

I get an error when trying:

kubectl cp /tmp/foo_dir <some-pod>:/tmp/bar_dir

Error:

rpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:235: starting container process caused "exec: "tar": executable file not found in $PATH"

kubectl kubernetes file-copying

It looks like there is no Tar into your Docker

I would suggest installing the Tar first at the above Dockerfile level commands

You can add the Tar into Docker using

Docker image : RUN yum install -y tar
