Chapter 4: Managing Cluster Configuration with Ansible

In Chapter 3, Provisioning Kubernetes Clusters Using AWS and Terraform, you learned how to create a Kubernetes infrastructure with Terraform and AWS, and you also learned how to develop infrastructure as code and provisioned your first production-like cluster.

This was just the first step towards building operational and production-ready Kubernetes clusters. By now, you should have an up-and-running cluster with Terraform infrastructure modules to provision other similar clusters.

These clusters are still plain; they're not configured or optimized to run production workloads. To make these clusters fully operational, we simply need to deploy and configure the required Kubernetes services for them.

In this chapter, you will design and develop a configuration management solution that you can use to manage the configuration of Kubernetes clusters and their supporting services. This solution is automated and scalable...
