fixing bug #78 (comment)

Doesn't seem related to #78, but I agree we should have this.
Can we have unit tests and integration tests?

fahedouch · 2021-03-30T16:38:40Z

@AkihiroSuda as we discussed on slack the test-docker-compatibility should fail anyway because docker in GHA doesn’t support IPv6 routing. can you check the PR plz!

Unneeded change

the length of ports slice should be 0 to avoid zero value (nil), nil value in this slice lead nil pointer execption.

I think these tests can be just UT, but if you prefer to have them as integration tests, these should be in port_test.go

you mean moving these tests into a port_test.go file will make them integration tests :o ?

@AkihiroSuda can you check plz ?

Setting up port forwarding for IPv6 does not require IPv6 routing

hi @AkihiroSuda

You should configure your cni to attribue an ipv6 to the container.

cat >/etc/cni/net.d/10-mynet.conf
{
        "cniVersion": "0.2.0",
        "name": "mynet",
        "type": "bridge",
        "bridge": "cni0", 
        "ipam": {
                "type": "host-local",
                "subnet": "2001:db8::/96",
                "routes": [
                        { "dst": "::/0" },
                        { "dst": "2001:db8::/96" }
                ]
        }
}

then I create a container with mynet network:

./nerdctl --snapshotter native run --network mynet  -d -p 80:80  alpine  sleep 300

./nerdctl ps
CONTAINER ID    IMAGE                              COMMAND        CREATED               STATUS    PORTS                                NAMES
7e31884d8ba0    docker.io/library/alpine:latest    "sleep 300"    About a minute ago    Up        0.0.0.0:80->80/tcp, :::80->80/tcp

Check the container ipv6

./nerdctl inspect 7e31884d8ba0

    {
        "Id": "7e31884d8ba01e9e3276c2b3cefda6a43f7ab1d097d45b7322ff3c401c923355",

        "Path": "sleep",
        "Args": [
            "300"
        ],
        "State": {
            "Status": "running",
            "Running": true,

        "Image": "docker.io/library/alpine:latest",
        "ResolvConfPath": "/var/lib/nerdctl/1935db59/containers/default/7e31884d8ba01e9e3276c2b3cefda6a43f7ab1d097d45b7322ff3c401c923355/resolv.conf",

        "Name": "",
        "Driver": "native",
        "Platform": "linux",
        "AppArmorProfile": "",
        "NetworkSettings": {
            "GlobalIPv6Address": "2001:db8::28",
            "GlobalIPv6PrefixLen": 96,
            "IPAddress": "",
            "IPPrefixLen": 0,
            "MacAddress": "0e:2f:cd:91:11:41",
            "Networks": {
                "unknown-eth0": {
                    "IPAddress": "",
                    "IPPrefixLen": 0,
                    "GlobalIPv6Address": "2001:db8::28",
                    "GlobalIPv6PrefixLen": 96,
                    "MacAddress": "0e:2f:cd:91:11:41"
                }
            }
        }
    }
]

And then I exec into the container to listen on 80

./nerdctl exec -ti 7e31884d8ba0  sh
/ # while true; do nc -l -p 80; done

then try to curl this container on its ipv6 2001:db8::28 :

./nerdctl --snapshotter native run --network mynet  --rm byrnedo/alpine-curl http://[2001:db8::28]
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:--  0:00:46 --:--:--     0

the curl is ok :

GET / HTTP/1.1
Host: [2001:db8::2a]
User-Agent: curl/7.66.0
Accept: */*

Doesn't seem related to port forwarding
