how to schedule pods in round robin fashion using nodeAffinity

[PRAKASH SINGH]

Hi All,

I am using kuberenetes for running NGINX.i have 10 nodes and one master. i want to schedule 4 NGINX pods in 3 selected machines in round-robin fashion.

1.is this possible?

2.nodeSelector is not useful

3.i tried below link

http://kubernetes.io/docs/user-guide/node-selection/#step-one-attach-label-to-the-node

but it' not scheduling pods as expected.

i am using k81.2

for more clarification on quiestion please refer below link:

I've responded on StackOverflow about the spreading question. (The answer is that if you specify resource request for your NGINX containers, the scheduler should spread the pods.)

Why do you say nodeSelector is not useful? That will ensure that your 4 pods can only run on the 3 selected machines.

i have not any concern about pod scheduling on the basis of resource avilable on the nodes.I just want to schedule pods on the specific nodes in the round robin fasion.if resource is not avilable for some node then i want to skip that node.

Let's have the discussion on StackOverflo so other people can find it in the future.
