Re: [kubernetes-users] Re: GKE - HPA scaling based on custom metrics.

[Raju Dawadi]

HPA to scale Deployment based on the custom metrics is now available 
according to release note and tut: 
https://cloud.google.com/kubernetes-engine/docs/tutorials/custom-metrics-autoscaling
 
But still I couldn't figure out way to scale with metric like 
http_requests. Any suggestion? Thanks.

Re: [kubernetes-users] How hostNetwork : true works with K8s Internal Services?

['Tim Hockin' via Kubernetes user discussion and Q]

Kubernetes does not demand an overlay, and most of the overlays used
for kube employ some form of node gateway to allow packets to cross
between planes.

Re: [kubernetes-users] How hostNetwork : true works with K8s Internal Services?

['Matthias Rampke' via Kubernetes user discussion and Q]

Hey,

yes, I think this should work for any reasonable overlay. NodePorts are
also implemented essentially in the host network namespace, so if this
wouldn't work you would not have *any* way of getting traffic into the
cluster at least as far as I can see.

Of course, the best way to find out for your particular environment is to
try!
