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.

FluentD and Google Cloud Logging


Looking back at the System pod listing screenshot at the beginning of the chapter, you may have noted a number of pods starting with the words fluentd-cloud-logging-kubernetes. These pods appear when using the GCE provider for your K8s cluster.

A pod like this exists on every node in our cluster, and its sole purpose is to handle the processing of Kubernetes logs. If we log in to our Google Cloud Platform account, we can see some of the logs processed there. Simply use the left side, and under Stackdriver, select Logging. This will take us to a log listing page with a number of drop-down menus on the top. If this is your first time visiting the page, the first drop-down will likely be set to Cloud HTTP Load Balancer

In this drop-down menu, we'll see a number of GCE types of entries. Select GCE VM instances and then the Kubernetes master or one of the nodes. In the second drop-down, we can choose various log groups, including kubelet. We can also filter by...
