Add Kubernetes Ingress support

Issues without logs and details cannot be debugged, and will be closed.

• I have tried with the latest version of my channel (Stable or Edge)
• I have submitted Diagnostics
• I have included the Diagnostics ID in this Issue

• Docker for Windows Version: 18.03.0-ce-win58 (16761)

I have installed the nginx-ingress-controller (0.10.2 from Kubernetes github) on my Kubernetes cluster and it seems to work fine. However, it exposes the node internal IP which is not directly accessible from a browser executing outside the cluster.

Expected behavior

It would be great to have a forwarding to localhost as it is the case with the LoadBalancer, but I suspect that it means a special ingress controller support inside "kubernetes for windows"

Actual behavior

The node internal IP is used as the exposed IP, this IP is unfortunately not accessible directly from the browser running on the main host.

Information

Steps to reproduce the behavior

1. Install nginx-ingress-controller as specified here: [https://github.com/kubernetes/ingress-nginx/blob/nginx-0.10.2/deploy/README.md] (note: I had some pb with more recent versions)
2. Create an ingress test case
3. kubectl get ing should show the node internal IP as the ADDRESS field

I got the ingress to work fine on docker-for-win by following the install instructions for mac located here

https://kubernetes.github.io/ingress-nginx/deploy/

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/mandatory.yaml

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/provider/cloud-generic.yaml

That will create the ingress controllers. Then you just need to create an ingress for one of your services

Example:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: vote-ingress
spec:
  rules:
  - host: vote.local.com
    http:
      paths:
      - path: /
        backend:
          serviceName: vote
          servicePort: 5000

@MikePugs you rock! The described steps for Docker for Mac work for Windows as well.

I also followed @MikePugs (on Windows) steps and it seems I am hitting the nginx-ingress-controller but getting the default 404. Likewise, the /healthz endpoint returns 200 The only difference in my set up is I need https (TCP 443) to work. Furthermore, in metadata, I added annotations:
kubernetes.io/ingress.class: "nginx"
nginx.org/ssl-services: "my-svc"
nginx.ingress.kubernetes.io/ssl-redirect: "false"
and finally applied namespaces "ingress-nginx" as well. Does someone have experience or can help with this development case?

Update... No more issues stated in the last post. As long as you pay attention to app labels everything works splendidly.

Ok, so for anyone still trying to make this work on docker-for-windows... What I had to do to make ingress "hosts" parameter work was map 127.0.0.1 to the desired url in the Windows\System32\drivers\etc\hosts file.

Sorry if it was obvious, it took sometime for me to realise. Working great now =D

[rabberbock]

@rodolfo-albuquerque Were you able to use multiple host names mapped to 127.0.0.1, and then map each one of those host names to a service in the cluster? Is there any additional setup you needed to get that working? Just adding it to the hosts file is not working for me.
