 FIRST=vm1.example.com
-set -u
 # copy secrets from $FIRST to this VM
 ssh $FIRST 'sudo podman run --rm --secret HIND_C,type=env hind sh -c "echo -n \$HIND_C"' |sudo podman secret create HIND_C -
 ssh $FIRST 'sudo podman run --rm --secret HIND_N,type=env hind sh -c "echo -n \$HIND_N"' |sudo podman secret create HIND_N -
