On Prem Kubernetes with 2 DCs

[zohebk8s]

Hi Team,

For etcd to work, a minimum of 3/5/7 nodes are required. In a two-data centres scenario, where I want to deploy Kubernetes on-premises.

I can spin up 1 etcd/DC-1& 2 etcd/DC-2, in this case if DC-2 is down or encounters some issues. Then the cluster won’t be consistent as etcd won’t work with 1 pod.(can’t write)

The question here is, if we have two data centres. Then we cannot deploy etcd into it?
