Overview of this book

Kubernetes is an open source orchestration platform for managing containers in a cluster environment. This Learning Path introduces you to the world of containerization, in addition to providing you with an overview of Docker fundamentals. As you progress, you will be able to understand how Kubernetes works with containers. Starting with creating Kubernetes clusters and running applications with proper authentication and authorization, you'll learn how to create high-availability Kubernetes clusters on Amazon Web Services (AWS), and also learn how to use kubeconfig to manage different clusters. Whether it is learning about Docker containers and Docker Compose, or building a continuous delivery pipeline for your application, this Learning Path will equip you with all the right tools and techniques to get started with containerization. By the end of this Learning Path, you will have gained hands-on experience of working with Docker containers and orchestrators, including SwarmKit and Kubernetes. This Learning Path includes content from the following Packt products: • Kubernetes Cookbook - Second Edition by Hideto Saito, Hui-Chuan Chloe Lee, and Ke-Jou Carol Hsu • Learn Docker - Fundamentals of Docker 18.x by Gabriel N. Schenker

Playing with WebUI


Kubernetes has a WebUI that visualizes the status of resources and machines, and also works as an additional interface for managing your application without command lines. In this recipe, we are going to introduce Kubernetes dashboard.

Getting ready

Kubernetes dashboard (https://github.com/kubernetes/dashboard) is like a server-side application. In the beginning, just make sure you have a healthy Kubernetes cluster running, and we will go through the installation and related setup in the coming pages. Since the dashboard will be accessed by the browser, we can use a minikube-booted, laptop-running Kubernetes system, and reduce procedures for forwarding network ports or setting firewall rules.

For Kubernetes systems booting up by minikube, check that both minikube and the system itself are working:

// check if minikube runs well
$ minikube status
minikube: Running
cluster: Running
kubectl: Correctly Configured: pointing to minikube-vm at 192.168.99.100
// check the Kubernetes...
