[qiliux]

The document about docker config missing a slash.
Online document address is: Official website pag

init_config:

instances:
  - url: "unix://var/run/docker.sock"

the slash (/) is important so that cloud insight can find the docker instances.
It should be:

init_config:

instances:
  - url: "unix:///var/run/docker.sock"

Finally make sure, you check the info about cloud insight and restart it.
