Q8
How do I tell that cluster 2 has an external ETCD datastore referenced based on the output of ps -aux | grep etcd?
It looks very similar to the output of cluster 1 which as a stacked ETCD datastore.
Is it simply because there is no --data-dir flag set for cluster 2?
Alistair Mackay:
It is not the datastore that determines whether etcd is external or not.
If etcd is external, then you will see no pod for etcd if you run
kubectl get pods -n kube-system
…because “external” means etcd runs as an operating system service (like kubelet) and not as a pod.
