The DevOps 2.3 Toolkit

By: Viktor Farcic

Overview of this book

Building on The DevOps 2.0 Toolkit, The DevOps 2.1 Toolkit: Docker Swarm, and The DevOps 2.2 Toolkit: Self-Sufficient Docker Clusters, Viktor Farcic brings his latest exploration of the DevOps Toolkit as he takes you on a journey to explore the features of Kubernetes. The DevOps 2.3 Toolkit: Kubernetes is a book in the series that helps you build a full DevOps Toolkit. This book in the series looks at Kubernetes, the tool designed to, among other roles, make it easier in the creation and deployment of highly available and fault-tolerant applications at scale, with zero downtime. Within this book, Viktor will cover a wide range of emerging topics, including what exactly Kubernetes is, how to use both first and third-party add-ons for projects, and how to get the skills to be able to call yourself a “Kubernetes ninja.” Work with Viktor and dive into the creation and exploration of Kubernetes with a series of hands-on guides.

Exploring virtual clusters

Almost all of the system services are running as Kubernetes objects. Kube DNS is a deployment. Minikube Addon Manager, Dashboard, Storage Controller, and nginx Ingress are a few of the system Pods that are currently running in our Minikube cluster. Still, we haven't seen them yet. Even though we executed kubectl get all quite a few times, there was not a trace of any of those objects. How can that be? Will we see them now if we list all the objects? Let's check it out.

kubectl get all  

The output shows only the objects we created. There are go-demo-2 Deployments, ReplicaSets, Services, and Pods. The only system object we can observe is the kubernetes Service.

Judging from the current information, if we limit our observations to Pods, our cluster can be described through the Figure 11-1.
