(Validation) HostConfig.PortBindings: unknown protocol: must be tcp or udp

[gbmeuk]

I believe we have found a divergence from standard docker here with this error.

The error is actually caused by using uppercase letters instead lowercase letters in the ports section of the docker-compose.yml file. For example:

    ports:
      - '8300-8302'
      - '8301-8302/udp'
      - '8600/udp'
      - '8600/tcp'
      - '8500'
      - '8400'
      - '53'

works but:

    ports:
      - '8300-8302'
      - '8301-8302/UDP'
      - '8600/UDP'
      - '8600/TCP'
      - '8500'
      - '8400'
      - '53'

fails with the stack trace:

It's also logged at INFO level instead of ERROR

This issue is not reproducible on Docker Engine
