Performing a Rolling Update of an Application in Kubernetes
In this hands-on lab, you will be presented with a three-node cluster. You will need to deploy your application, so you can begin serving your end users. You will deploy the image from linuxacademycontent/kubeserve:v1 and then verify the deployment was successful. Once your application is running and serving clients, you will perform a rolling update, making sure the rollout is successful and there is no downtime for your end users. You will make use of the kubectl command line tool to perform all operations, in combination with the
set image command to perform the rolling update to the new version. When you have verified the end users are now using version 2 of the app versus version 1, you may consider this hands-on lab complete.
