# 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
works, but then a pod should be running. The problem is that the file has to be copied before the pod starts. The jar file has to be loaded by an Application server. Destroying the pod after the copy will not work as the docker image is deployed again and the content will be wiped out.
A configMap was misused to copy the jar before the pod starts, but that only seems to work for configuration files. This was confirmed by comparing the checksum, e.g. local vs. remote.
