Set Up Kubernetes Cluster
First, we need a Kubernetes cluster. You may use an existing one or set up a new one. For this tutorial, we chose to use GKE (Google Kubernetes Engine).
Just follow the quick start to create a cluster. To save your money, the default pool with only one node is sufficient for our testing. For node image type, use the default Container-Optimized OS; for machine type, please select one with at least 8G mem. After creating the cluster, go ahead to configure kubectl to connect to the cluster following this guide.
