Set the node named ek8s-node-1 as unavailable and reschedule all the pods running on it.

Remove taint added to node "worker-2"

Create a deployment as follows:
* Name: nginx-app
* Using container nginx with version 1.11.10-alpine
* The deployment should contain 3 replicas
Next, deploy the application with new version 1.11.13-alpine, by performing a rolling update.
Finally, rollback that update to the previous version 1.11.10-alpine.

Evict all existing pods from a node-1 and make the node unschedulable for new pods.

Create a Pod nginx and specify both CPU, memory requests and limits together and verify.
