Re: [kubernetes-users] Re: Low throughput on K8s LoadBalancer

Do you have more details on the resource you were running out of on the Tomcast containers? Were you CPU bound? Perhaps K8s is limiting the number of CPU's available in a different fashion than what docker was. Could you include the Tomcat iostat, vmstat, etc. output? -EJ On Tue, Sep 19, 2017

Re: [kubernetes-users] Re: Low throughput on K8s LoadBalancer

Sorry, not sure I parsed your reply. If you test docker with client and server on the same node, you need to test kubernetes the same way. You can test your client to the pod's IP directly (should be same as docker perf) and then test kube services. On Tue, Sep 19, 2017 at 10:16 PM, Vinoth

Re: [kubernetes-users] Re: Low throughput on K8s LoadBalancer

Tim u mean the backend for k8s node is same as the result of the backend on native tomcat test as well as on the docker. k8s node backend is different that the tomcat and docker test. Tomcat/docker test did on the GCP machine with ubuntu flavour with 8cpu/30Gig machine k8s test did on 3

Thanks for the response Tim. I don't see any failures in the ab result all the request got successful in all the test. The following are the results that I attached in the GitHub. https://github.com/kubernetes/kubernetes/issues/52652 k8s_service.txt

Re: [kubernetes-users] Low throughput on K8s LoadBalancer

Sounds like subtly differences in the tests that make the performance metric more realistic for kube and more like a theoretical max test when you run docker measurements. Two ways to even the playing field: 1) If you run the test inside the kube pod does it have the same performance as the

Re: [kubernetes-users] Re: Low throughput on K8s LoadBalancer

NodePort vs VIP should have no difference - they traverse the same paths. This is a much steeper difference than what I measured and more than I would expect. Is this 8k new connections per second? Could you be exhausting conntrack records and getting some failures? It would be interesting to

Re: [kubernetes-users] steps to migrate Docker image to use kubernetes

Your volume config is not valid. What you need depends on whether you want your volume to literally map `/c/Users/abcd/config` (which you manage out of band, kubernetes won't touch) into your container or whether you want just "an empty directory". The literal equivalent would be more like: ```

[kubernetes-users] Re: Low throughput on K8s LoadBalancer

Debugging performance issues on Docker/Kube can be interesting You could try exposing the service through a Nodeport, and run your benchmark directly against the node IP. That would at least tell you if the GKE LB is a factor or not. Also - are your pods possibly CPU or memory limited

I think this can probably be done using custom metrics: https://kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale/#support-for-custom-metrics I have not used custom metrics, so it's not something I really know about :-) On Tuesday, September 19, 2017, Parth Gandhi

hello, i've tried setuping a local cluster and after a lot of trial and error that worked well for 1.7.5. but my current employer is interested into kubernetes contributions, so i've tried building and running the most recent github maste,r so that i can try to understand the project upstream.

[kubernetes-users] Autoscale pods based on the queue size threshold

Hi, we have an console application running in the pods in kubernetes cluster. We have a DB table that keeps the count of incoming queue messages. We need to autoscale the pods when the table reaches certain threshold values. can this be achieved using k8s HPA? or do we need to write a different
