Getting Started with Kubernetes - Third Edition

By: Jonathan Baier, Jesse White

Overview of this book

Kubernetes has continued to grow and achieve broad adoption across various industries, helping you to orchestrate and automate container deployments on a massive scale. Based on the recent release of Kubernetes 1.12, Getting Started with Kubernetes gives you a complete understanding of how to install a Kubernetes cluster. The book focuses on core Kubernetes constructs, such as pods, services, replica sets, replication controllers, and labels. You will understand cluster-level networking in Kubernetes, and learn to set up external access to applications running in the cluster. As you make your way through the book, you'll understand how to manage deployments and perform updates with minimal downtime. In addition to this, you will explore operational aspects of Kubernetes , such as monitoring and logging, later moving on to advanced concepts such as container security and cluster federation. You'll get to grips with integrating your build pipeline and deployments within a Kubernetes cluster, and be able to understand and interact with open source projects. In the concluding chapters, you'll orchestrate updates behind the scenes, avoid downtime on your cluster, and deal with underlying cloud provider instability within your cluster. By the end of this book, you'll have a complete understanding of the Kubernetes platform and will start deploying applications on it.

Chapter 9. Operating Systems, Platforms, and Cloud and Local Providers

The first half of this chapter will cover how open standards encourage a diverse ecosystem of container implementations. We'll look at the Open Container Initiative (OCI) and its mission to provide an open container specification as well. The second half of this chapter will cover the various operating systems available for running containerized workloads, such as CoreOS. We'll also look at its advantages as a host OS, including performance and support for various container implementations. Additionally, we'll take a brief look at the Tectonic Enterprise offering from CoreOS. We'll look at the various hosted platforms offered by the major cloud service providers (CSPs) and see how they stack up.

This chapter will discuss the following topics:

  • Why do standards matter?
  • The OCI and the Cloud Native Computing Foundation (CNCF)
  • Container specifications versus implementations
  • Various container-oriented operating systems
  • Tectonic
  • The...
