Exposed port to multiple addresses: only one IP address shows up

[bfejervari]

I have a docker container (FreeIPA), which has it's DNS server port (:53) exposed to 127.0.0.1 and 192.168.200.8 addresses.
The docker run command part:

    -p 127.0.0.1:53:53 -p 127.0.0.1:53:53/udp \
    -p 192.168.200.8:53:53 -p 192.168.200.8:53:53/udp \

The same part in the docker inspect output:

                "53/tcp": [
                    {   
                        "HostIp": "127.0.0.1",
                        "HostPort": "53"
                    },
                    {   
                        "HostIp": "192.168.200.8",
                        "HostPort": "53"
                    }
                ],
                "53/udp": [
                    {   
                        "HostIp": "127.0.0.1",
                        "HostPort": "53"
                    },
                    {   
                        "HostIp": "192.168.200.8",
                        "HostPort": "53"
                    }
                ],

The problem: using runlike shows only the first IP address as a -p ... parameter.

Indeed it seems runlike only uses the first item in the list:

runlike/runlike/inspector.py

Line 109 in 1e5a8a2

host_ip = options[0]['HostIp']

A good first issue to try to solve if someone wants to have a crack at this.
Thank you for reporting!

@lavie I've verified that this problem no longer exists.

Docker run:
docker run --name ubuntu -p 127.0.0.1:53:53 -p 127.0.0.1:53:53/udp -d ubuntu sleep infinity

Runlike output:
docker run --name=ubuntu --hostname=a4fee37b7072 --mac-address=<redacted> --network=bridge -p 127.0.0.1:53:53 -p 127.0.0.1:53:53/udp --runtime=runc --detach=true ubuntu sleep infinity

The issue can be closed now.

Indeed it was recently solved by a contributor probably in this PR: #116
Thank you for noticing. Will close this now.
