newbie - changed yaml - what to do to update k8s cluster with same

Question

Let's say I have a deploymnet.yaml or PVC.yaml. I update the yaml file with some values. What should I do? Apply again? Sorry for newbie question I searched and went through documentation and came across rolling updates and record which I believe is further down the learning curve for me.

kubectl apply -f pvc.yaml # first run

Changes made to file

kubectl apply -f pvc.yaml # run again to update?

I created efs-provisioner without rbac and I believe pvc is in pending status because of it. So trying to update the yamls to accommodate the change.

Yes, run again.

Kubernetes will take care of the rests.

yes, you can. If you need blue/green deployment, then you need do some extra jobs. – BMW Mar 04 '19 at 23:32
