OS: Fedora 31 (64 bit)
podman: 1.9.0
minikube: 1.10.0-beta.2

Error description: when I try to start minikube with podman driver, it fails with the following message:

failed to start node: startup failed: Failed to setup kubeconfig: RoutableHostIPFromInside is currently only implemented for docker https://github.com/containers/libpod/issues/5205

I'm not quite sure if that bug is relevant (no mention of RoutableHostIPFromInside).

Steps to reproduce the issue:

  1. minikube start --driver=podman

Full output of failed command:

Not sure what the fix is, for Docker we use the local bridge:

// dockerGatewayIP gets the default gateway ip for the docker bridge on the user's host machine
// gets the ip from user's host docker
func dockerGatewayIP() (net.IP, error) {
        rr, err := runCmd(exec.Command(Docker, "network", "ls", "--filter", "name=bridge", "--format", "{{.ID}}"))
        if err != nil {
                return nil, errors.Wrapf(err, "get network bridge")
        }

        bridgeID := strings.TrimSpace(rr.Stdout.String())
        rr, err = runCmd(exec.Command(Docker, "inspect",
                "--format", "{{(index .IPAM.Config 0).Gateway}}", bridgeID))
        if err != nil {
                return nil, errors.Wrapf(err, "inspect IP bridge network %q.", bridgeID)
        }

        ip := net.ParseIP(strings.TrimSpace(rr.Stdout.String()))
        glog.Infof("got host ip for mount in container by inspect docker network: %s", ip.String())
        return ip, nil
}

Presumably something similar, to get the podman CNI bridge ?

$ sudo podman network ls --filter name=bridge
Error: unknown flag: --filter
$ sudo podman network ls
NAME     VERSION   PLUGINS
podman   0.4.0     bridge,portmap,firewall,tuning

Not sure how to inspect it, though. Poke around in /etc/cni ?

{
  "cniVersion": "0.4.0",
  "name": "podman",
  "plugins": [
    {
      "type": "bridge",
      "bridge": "cni-podman0",
      "isGateway": true,
      "ipMasq": true,
      "ipam": {
        "type": "host-local",
        "routes": [{ "dst": "0.0.0.0/0" }],
        "ranges": [
          [
            {
              "subnet": "10.88.0.0/16",
              "gateway": "10.88.0.1"
            }
          ]
        ]
      }
    }
  ]
}

Or just look at the Gateway of the container maybe ?

            "Gateway": "10.88.0.1",
            "IPAddress": "10.88.0.2",

Could probably do that for docker as well as for podman:

            "Gateway": "172.17.0.1",
            "IPAddress": "172.17.0.2",

We can access the container's gateway via the following command:

podman inspect --format "{{.NetworkSettings.Gateway}}" $CONAINTER_ID_OR_NAME

Thing is: do we have the container's ID or name?

We do.

// RoutableHostIPFromInside returns the ip/dns of the host that container lives on
func RoutableHostIPFromInside(ociBin string, containerName string) (net.IP, error)

Left the docker hacks in place. Not sure what do for podman-remote, lookup the host name ?
