Re: [kubernetes-users] ClusterIP service not distributing requests evenlyamong pods in Google Kubernetes Engine

I haven't checked, but I'd bet that the C++ gRPC library uses HTTP2, which seems to explicitly encourage connection reuse, which leads to this behavior. If you search around you may be able to find some options. On Fri, Apr 13, 2018 at 11:18 AM wrote: > > I am using

Re: [kubernetes-users] ClusterIP service not distributing requests evenlyamong pods in Google Kubernetes Engine

I am using gRPC on both sides, both in C++. The client sends asynchronous requests. A new channel is created (and destroyed) with every request. Thank you! On Friday, April 13, 2018 at 2:09:48 PM UTC-4, Tim Hockin wrote: > What are you using for a client?  Is it by chance http and written in

Re: [kubernetes-users] ClusterIP service not distributing requests evenlyamong pods in Google Kubernetes Engine

What are you using for a client? Is it by chance http and written in go? Some client libraries, including Go's http, aggressively reuse connections. If you try with something like exec netcat, I bet you see different results. BTW, one might argue that if you depend on RR, you will eventually be

Re: [kubernetes-users] ClusterIP service not distributing requests evenlyamong pods in Google Kubernetes Engine

I am running them against the service's cluster IP address (through its name, i.e. "btm-calculator" which translates to the cluster IP), and port 3006. On Friday, April 13, 2018 at 1:19:32 PM UTC-4, Rodrigo Campos wrote: > And how are you running the requests? Against which IP and which port?

Re: [kubernetes-users] ClusterIP service not distributing requests evenlyamong pods in Google Kubernetes Engine

And how are you running the requests? Against which IP and which port? On Fri, Apr 13, 2018 at 10:17:04AM -0700, cristian.coch...@gmail.com wrote: > > OK, I changed my pods to respond almost immediately so that I can test with a > statistically significant number of requests (10,000), and I am

Re: [kubernetes-users] ClusterIP service not distributing requests evenlyamong pods in Google Kubernetes Engine

OK, I changed my pods to respond almost immediately so that I can test with a statistically significant number of requests (10,000), and I am still observing the same behavior, only 1 pod receives all 10k requests. Can anyone explain why this happens? I am including the service and deployment

Re: [kubernetes-users] ClusterIP service not distributing requests evenlyamong pods in Google Kubernetes Engine

Thank you Tim. Is there now way to set it to true RR? If not, I will have to do my own balancing, if there is no other suggestion. On Friday, April 13, 2018 at 10:59:46 AM UTC-4, Tim Hockin wrote: > Without a statistically significant load, this is random.  What you are > seeing satisfies

RE: [kubernetes-users] ClusterIP service not distributing requests evenlyamong pods in Google Kubernetes Engine

To: Kubernetes user discussion and Q Subject: [kubernetes-users] ClusterIP service not distributing requests evenlyamong pods in Google Kubernetes Engine I have a ClusterIP service in my cluster with 4 pods behind it. I noticed that requests to the service are not evenly distributed among pods
