# Porter for a Docker host: open http://localhost:6080
#
# pid: host shares the host's process namespace, so Porter reads the host's
# socket table (through /proc/1/net) and names the process behind each port.
# On Docker Desktop (Windows, macOS) the host is Docker's Linux VM, which is
# where your containers' published ports live.
