Patching Live Kubernetes Deployments and Draining a Node for Maintenance

This lab guides the student through the creation of a cluster using kops. Once created, the cluster is used to deploy four replicas of the NGINX web server. Then the kubectl patch command is used to update the version of NGINX running in the pod containers. The last exercise is to drain a node for maintenance.
