In this chapter, we focused on common operational best practices for Kubernetes clusters running in production. First, we covered the approaches for provisioning infrastructure for Kubernetes and deploying the clusters reproducibly—we introduced the concepts of infrastructure as code and immutable infrastructure and have showed how they fit into the Kubernetes landscape. Additionally, we provided a recommendation on the best tools for provisioning infrastructure and cluster Deployments. Next, you learned what GitOps is and how to apply this philosophy using Flux and Git repositories. We focused on the operational aspects of upgrades and the patching of both the underlying cluster infrastructure and Kubernetes itself. And lastly, you learned how to ensure that your Kubernetes cluster can run behind HTTP(S) network proxies in enterprise environments.
Congratulations...
