By the end of the tutorial, you will automate creating three clusters (dev, staging, prod) complete with the GKE Ingress in a single click. A Kubernetes service for each routing rule where Ambassador configurations such as retry policies and connection timeouts can be applied as annotations. Then Terraform configures and deploys two instances each of the load balancer image and the two web server images, setting up high availability with GCE health checks. When we deploy a public HTTP (S) load balancer, we need to use instance groups to organize instances. The most typical setup is a Virtual Private Cloud (VPC) with a public and a private subnet. Private subnets Must be tagged as follows so that Kubernetes and the AWS load balancer controller know that the subnets can be used for internal load balancers. Provisioning Kubernetes clusters on GCP with Terraform and GKE. Setting up a load balancer requires provisioning three types of resources. When the Load Balancer connectivity is unavailable, the most common symptoms are as follows: VMs behind the Load Balancer aren't responding to health probes.
