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.

Maturing our monitoring operations


While Grafana gives us a great start to monitoring our container operations, it is still a work in progress. In the real world of operations, having a complete dashboard view is great once we know there is a problem. However, in everyday scenarios, we'd prefer to be proactive and actually receive notifications when issues arise. This kind of alerting capability is a must to keep the operations team ahead of the curve and out of reactive mode.

There are many solutions available in this space, and we will take a look at two in particular: GCE monitoring (Stackdriver) and Sysdig.

GCE (Stackdriver)

Stackdriver is a great place to start for infrastructure in the public cloud. It is actually owned by Google, so it's integrated as the Google Cloud Platform monitoring service. Before your lock-in alarm bells start ringing, Stackdriver also has solid integration with AWS. In addition, Stackdriver has alerting capability with support for notification to a variety of...
