ports is commented out

[zznathans]

the default config relies on the 8081:8081 ports to be defined. That actual line is fine, but the "ports" line above it is commented out, thus rendering it useless:

    # ports:
      # - "53:53/tcp"
      # - "53:53/udp"
      - "8081:8081"

un-commenting the first line resolves this
