Can I create an ingress instance on coreos ?

[Thomas Privat]

Hello all,

Im wondering if an ingress instance is working on coreos or if its especially designed to work with GCE ?

When I greate an ingress instance with the following yaml file:

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: basic-ingress
spec:
  backend:
    serviceName: nginx
    servicePort: 80

I will get no IP Address for communication with the instance assigned:

$ kubectl describe ing basic-ingress
Name:            basic-ingress
Namespace:        default
Address:        
Default backend:    nginx:80 (<none>)
Rules:
  Host    Path    Backends
  ----    ----    --------
  *    *     nginx:80 (<none>)
Annotations:
No events.

Any ideas about this ?

Cheers, Thomas

Absolutely, you can.  I have quite a number of Ingress resources deployed on my baremetal CoreOS boxes.

Keep in mind, though, that an Ingress, by itself, does nothing useful.  You also need to have backends/Services and Endpoints on which it operates.

Most importantly, though, you need an IngressController to be running.  If you are not on an otherwise supported platform (GCE, AWS), a good choice is the nginx-based IngressControler at  https://github.com/kubernetes/contrib/tree/master/ingress/controllers/nginx .   This is what actually does the binding and discovery to _do_ something with the Ingress.
