Overview

In this lab you will learn how to:

• Provision a complete Kubernetes cluster using Kubernetes Engine.
• Deploy and manage Docker containers using kubectl.
• Break an application into microservices using Kubernetes' Deployments and Services.

Kubernetes is all about applications. In this part of the lab you will use an example application called "app" to complete the labs.

App is hosted on GitHub and provides an example 12-Factor application. During this lab you will be working with the following Docker images:

• kelseyhightower/monolith - Monolith includes auth and hello services.
• kelseyhightower/auth - Auth microservice. Generates JWT tokens for authenticated users.
• kelseyhightower/hello - Hello microservice. Greets authenticated users.
• nginx - Frontend to the auth and hello services.

Kubernetes is an open source project (available on kubernetes.io) which can run on many different environments, from laptops to high-availability multi-node clusters, from public clouds to on-premise deployments, from virtual machines to bare metal.

For this lab, using a managed environment such as Kubernetes Engine allows you to focus on experiencing Kubernetes rather than setting up the underlying infrastructure.
