Thanks, Jaice ! I'll followup on Monday. Coincidentally, I'm off on vacation for ~2 weeks starting Tuesday, so there might be a brief hiatus in subsequent action. But hopefully I'll be able to leave knowing that SIG-GCP will indeed become a thing :) - Adam On Fri, Aug 11, 2017 at 12:03 PM

Re: [kubernetes-users] Generally speaking, separate apps = separate clusters, right?

Tim, This is a hugely appreciated answer. Sorry the question was so generic! For now, we'll chose separate clusters - understanding the sub-optimal side effects of that decision. We'll revisit the single-or-multiple cluster question in a year or so, once we've had a reasonable amount of

Re: [kubernetes-users] Generally speaking, separate apps = separate clusters, right?

I think Tim described the situation well. Multi-tenancy is something that we are giving increased attention to now. For many multi-tenant scenarios, the required features are already there, just without a great UX (it's "possible" but not "easy"), and without best-practices docs to pull together

Great overview Tim! This should be an FAQ item somewhere. On Fri, Aug 11, 2017 at 4:55 PM 'Tim Hockin' via Kubernetes user discussion and Q wrote: > This is not an easy question to answer without opining. I'll try. > > Kubernetes was designed to model Borg.

[kubernetes-users] k8s networking / cluster size limits confusion

According to the docs, k8s can support systems of up to 15 pods. (See https://kubernetes.io/docs/admin/cluster-large/) But given k8s' networking model, I'm a bit puzzled on how that would work. It seems like a typical setup is to assign a service-cluster-ip-range with a /16 CIDR. (Say

Re: [kubernetes-users] Unable to write into K8S mounted volume

If you are using NFS, then you should configure the NFS (IIRC /etc/exports, but it's been some years now :-D) with proper permissions. Have you done that too? On Fri, Aug 11, 2017 at 9:59 AM, Kubernetes user discussion and Q wrote: > I am trying to mount a

Re: [kubernetes-users] k8s networking / cluster size limits confusion

Oh hold on. the *service cluster IP range* is not for pod IPs at all. It's for the ClusterIP of services, so you can have up to 64k services in a cluster at the default setting. The range for pods is the --cluster-cidr flag on kube-controller-manager. On Fri, Aug 11, 2017 at 3:05 PM David

Re: [kubernetes-users] k8s networking / cluster size limits confusion

Kuberentes will be giving a /24 to each node, not each pod. Each node will give one IP out of that /24 to a pod it controls. This default means you can have 253 pods-per-node. This of course can be adjust depending on the size of your pods and nodes. This means that you can fully utilize the

Re: [kubernetes-users] k8s networking / cluster size limits confusion

Actually, that begs another question. The docs also specify that k8s can support up to 5000 nodes. But I'm not clear on how the networking can support that. So let's go back to that service-cluster-ip-range with the /16 CIDR. That only supports a maximum of 256 nodes. Now the maximum
