Bind test services to an IP other than localhost

[ns-sjorgedeaguiar]

Hi,

I'm trying to expose the test cluster to a docker network but it fails to start with the default namespace not being created before the timeout. Looks like the API is not able to connect to etcd. What is the right way to get this working? I tried setting the etcd url

etcdURL := &url.URL{
	Scheme: "http",
	Host: ips[0].String() + ":2379",
}

testEnv := &envtest.Environment{
	ControlPlaneStartTimeout: time.Hour,
	CRDDirectoryPaths: crdDirs,
	ControlPlane: envtest.ControlPlane{
		APIServer: &envtest.APIServer{
			EtcdURL: etcdURL,
			SecureServing: envtest.SecureServing{
				ListenAddr: envtest.ListenAddr{
					Address: ips[0].String(),
					Port:    listenPort,
				},
			},
		},
		Etcd: &envtest.Etcd{
			URL: etcdURL,
		},
	},
}

But this didn't work, same error. Also tried setting listen-client-urls, advertise-address and listen-peer-urls in the etcd and api server, to no avail. Is this supported?
