Deploying to a Google Kubernetes Engine Cluster

The strength and flexibility of Kubernetes is built around the concept of containerized applications, which are deployed differently from non-containerized apps. In this hands-on lab, you’ll complete all the steps from creating a Kubernetes cluster to confirming the deployed application, including creating the Docker image of your application, pushing that image to Container Registry, deploying the workload, and then configuring a load balancer to expose it.
