Re: [kubernetes-users] kube-proxy creating iptable rule for wrong interface

This behavior puzzles me. API service is definitely a unique service, but this issue can be tough debug, and causes a problem if some traffic needs to be sent through a security device for monitoring. Let me explain: - Assume there is no direct API connectivity between worker nodes and

Re: [kubernetes-users] Kubernetes Volume storage questions

The main difference is that EBS and things like that are fully managed, and you should be able to assume some operational simplicity (if their capabilities meet your needs). If you need multi-writer, for example, EBS will not suffice. Clustered filesystems require YOU to operate them (for now?),

Re: [kubernetes-users] Kubernetes Volume storage questions

The first are clustered filesystems, you don't need that complication. EBS is just a block device, probably the same is true for VMware. But feel free to read about them, it's a subject on its own and not at all Kubernetes specific On Tuesday, January 2, 2018, DK

Or just a pvc (a volume claim) that by default in one cluster is ebs and the other is the one for VMware? Take a look into PVC doc, it might be just what you want :-) On Tuesday, January 2, 2018, DK wrote: > Hi, > > My Kubernetes cluster will be running on VmWare and

Services are just to expose. So you can just a deployment and decide (or autoscale) the replicas :) On Tuesday, January 2, 2018, Mario Rodriguez wrote: > good question, I thought you always needed a Service when running an app > in k8s. > > On Monday, January 1, 2018 at

good question, I thought you always needed a Service when running an app in k8s. On Monday, January 1, 2018 at 10:51:48 PM UTC-6, Tim Hockin wrote: > > Why do you need a Service at all? > > On Jan 1, 2018 8:43 PM, "Mario Rodriguez" > wrote: > >> Hi, I'm in the middle of

[kubernetes-users] Kubernetes Volume storage questions

Hi, My Kubernetes cluster will be running on VmWare and in future on Amazon's AKS also. What should I be looking for regards Volume drivers? - Cepth, GlusterFS seem to be popular options. - RexRay seems to be popular in Docker with a FlexRay K8s option Or should I be looking at
