Create kubernetes setup with 1 master 3 nodes #2

currently, I see once 3 vms are created in gd2-k8s cluster kube1 kube2 kube3 is it meant to be 3 nodes and 1 of the node is considered a master? if yes, can we separate out the master by creating a cluster of 1 master and 3 nodes setup?

Why though? What do you get by having a separate master?

Madhu-1 commented 6 years ago

it good to have a separate master as we should not disturb the workload on master VM. if we start bringing the containers(app pods) on the master node, even after some time the master components will go down due to the resource constraints.

I agree with @Madhu-1 , master is normally unschedulable. So its better to have one master and 3 worker nodes.

kshlm commented 6 years ago

Kubespray defaults to having 2 master nodes though. So the load gets shared. But anyways, how big of a concern is this, just for a local development deployment? We are not saying that this is the preferred setup for production deployments.

@kshlm we are planning to make use of this for CSI driver e2e testing with all the driver functionalities. I expect a moderized load in such a setup.
