copy and paste this one-liner into a terminal of the docker host you want to debug. this will dump all the cli api calls between the client and docker host. requires root and the app socat.

	&& socat -v UNIX-LISTEN:/var/run/docker.sock,group=docker,perm=0660,reuseaddr,fork UNIX-CONNECT:/var/run/docker.sock.orig; \
