Summary

In this chapter, we first started exploring object management methods in Kubernetes. We learned about imperative commands using kubectl, how to combine imperative commands using configuration files, and, finally, we demonstrated some declarative configuration approaches using examples. Following this, we discussed how services are a crucial Kubernetes resource, which are used to connect microservices in clusters. We used hands-on exercises to show how microservice applications should be configured in order to discover other applications. Since it is now possible to create more complex applications by interacting with each other, their resource files will be more complex to manage. Therefore, we presented the official Kubernetes package manager, Helm. Helm separates the resource definition and configuration values to install applications using a couple of commands. At the end of the chapter, Helm was utilized to install and scale up a blog application. Deploying applications...
