Overview of this book

Kubernetes has been widely adopted across public clouds and on-premise data centers. As we're living in an era of microservices, knowing how to use and manage Kubernetes is an essential skill for everyone in the IT industry. This book is a guide to everything you need to know about Kubernetes—from simply deploying a container to administrating Kubernetes clusters wisely. You'll learn about DevOps fundamentals, as well as deploying a monolithic application as microservices and using Kubernetes to orchestrate them. You will then gain an insight into the Kubernetes network, extensions, authentication and authorization. With the DevOps spirit in mind, you'll learn how to allocate resources to your application and prepare to scale them efficiently. Knowing the status and activity of the application and clusters is crucial, so we’ll learn about monitoring and logging in Kubernetes. Having an improved ability to observe your services means that you will be able to build a continuous delivery pipeline with confidence. At the end of the book, you'll learn how to run managed Kubernetes services on three top cloud providers: Google Cloud Platform, Amazon Web Services, and Microsoft Azure.

Azure Kubernetes service

Azure Kubernetes service is a hosted Kubernetes service in Azure. A cluster contains a set of nodes (such as Azure VMs). Just like a normal Kubernetes node, kube-proxy and kubelet are installed on the node. kube-proxy, which communicates with the Azure virtual NIC, manages the route in and out for services and pods. kubelet receives the request from the master, schedules the pods, and reports the metrics. In Azure, we could mount various Azure storage options such as Azure disk and Azure files as the Persistent Volume (PV) for persisting the data for containers. An illustration of this is shown here:
