Running this compose file against Docker running Kitematic in Windows :

scope:
   image: weaveworks/scope:1.6.4
   ports:
     - "0.0.0.0:4040:4040"
   network_mode: "host"
   pid: "host"

   labels:
     - "works.weave.role=system"
   volumes:
     - "/var/run/docker.sock:/var/run/docker.sock:rw"
   command:
     - "--probe.docker=true"

and the Scope app does not show any containers.

Removing network: ["host"] from the compose file results in an app that shows containers.

Sharing the /var/run/docker.sock in Kitematic breaks it again.

Before sharing: 1

After sharing: 2

It looks like the underlying problem here is

Docker: problem with bridge docker0: route ip+net: no such network interface
Error getting docker bridge ip: route ip+net: no such network interface

which likely comes from net.InterfaceByName.
