Support ingress

[tayzlor]

Would be good to have some out-of-the box options for Kubernetes Ingress controllers.

Needs to be more along the lines of https://github.com/nginxinc/kubernetes-ingress or even moving out to seperate machines for loadbalancing like http://www.devoperandi.com/load-balancing-in-kubernetes/

[enxebre]

could put in place a pluggable fashion approach so user can choose at the time of deploying the platform

@enxebre VAMP is very much about high-level "canary" patterns, providing f.e. specific percentages, NOT/AND/OR logic, conditions and filter-weights, to setup complex "buckets/segments" of visitors, and route them dynamically. We currently use HAproxy's to do this, but if Ingress provides the same feature-set as HAProxy ACL's we could integrate our VampGatewayAgents with Ingres instead of HAproxy.

@olafmol The way I see the community going is a lot of people will use the out of the box GCE or AWS loadbalancer but this offers very simple routing. Anything more complex I see them using Ingress and Ingress controllers. The Ingress controllers are pods that listens to the /ingresses endpoint to update itself and acts as a load balancer for Ingresses. It also listens on its assigned port for external requests. People have done examples running nginx ingress controllers and i have also seen haproxy and traefik ingress controllers. So this might be the way to go

[olafmol]

@wallies Yes, it would definately be feasible to integrate/extend Ingress with VAMP and use our VampGatewayAgents(VGA's)+HAProxy as Ingress-controllers. They are already designed to run in HA & high-performance setups, and support complex patterns like service-draining etc. This can also act as a service-loadbalancer while ingress is getting more mature. Would that make sense?

Traefik is pending support for it: traefik/traefik#186

We have been using this https://github.com/albertrdixon/romulus + vulcand for a while.

Closing this as ce2a684 got in
