Hello! Docker newbie here.
Can someone please tell me how docker sockets are supposed to be running?
While playing/poking around, I found several unix sockets for docker running on a host (just trying to understand things). I though only one socket is supposed to be running ?
This is the output of netstat -a --protocol=unix
netstat -a --protocol=unix
