When I start the container by docker-compose up with the following configuration:

dns:
  container_name: dns_server
  image: iverberk/docker-spy
  ports:
   - "53:53/udp"
   - "53:53"
  volumes:
    - /var/run/docker.sock:/var/run/docker.sock
  environment:
    - DNS_DOMAIN=dev

the container terminates with the errors below:

Update: I recompiled the docker-spy binary with go 1.6.1 and re-created the Docker image. Now the issue has gone away.
