ERROR: you need to share your Docker host socket with a volume at $socket_file

Typically you should run your jwilder/nginx-proxy with: \`-v /var/run/docker.sock:$socket_file:ro\`

If you are running your daemon over TLS, make sure you are also exposing it over a Unix socket
|

with the -H unix:///var/run/docker.sock argument
