Kubernetes - One request per container inside a pod

1/30/2018

How can i control the distribute of requests inside a pod? For example: I have one pod with one container that runs NodeJs Hello world with 10sec sleep. At first without scaling, i just want to hold other requests until the container finish processing a request.

Im trying to implement a simple Function as a service with Kubernetes.

Since Kubernetes support ingress controller, you may configure nginx like this below:

limit_req_zone $binary_remote_addr zone=mylimit:10m rate=10r/s;

server {
location /login/ {
    limit_req zone=mylimit;


    proxy_pass http://my_upstream;
}
}

But if you want to limit rate by using kubernetes resource quota, the github issue: https://github.com/kubernetes/kubernetes/issues/2856 may be useful
