Summary

In this chapter, we first described the characteristics of Kubernetes and the essential solutions it offers for running cloud-native microservice applications. Following that, we then presented Kubernetes architecture with the details of master and node components. Furthermore, a local Kubernetes solution was installed and run to show the components of the Kubernetes architecture in action. Then, we discussed how to access Kubernetes clusters to send workloads, and troubleshoot running applications with the help of the Kubernetes dashboard and the Kubernetes CLI tool.

Finally, the fundamental set of Kubernetes resources are presented, including pods, replication sets, deployments, and stateful sets. Also, the importance of labels was mentioned in explaining how Kubernetes handles these resources. At the end of the chapter, the popular blog application, WordPress, was installed in Kubernetes with its database as a stateful set.

With the fundamental basis of Kubernetes covered in this chapter, creating production-ready Kubernetes clusters and managing sophisticated applications on these clusters will be covered in the following chapters.
