Kubernetes Tutorial Kubernetes Basics: This tutorial provides a walkthrough of the basics of the Kubernetes cluster orchestration system. Each module contains some background information on major Kubernetes features and concepts, and includes an interactive online tutorial. These interactive tutorials let you manage a simple cluster and its containerized applications for yourself. Using the interactive tutorials, you can learn to: ● Deploy a containerized application on a cluster ● Scale the deployment ● Update the containerized application with a new software version ● Debug the containerized application
The tutorials use Katacoda to run a virtual terminal in your web browser that runs Minikube, a small-scale local deployment of Kubernetes that can run anywhere. There's no need to install any software or configure anything; each interactive tutorial runs directly out of your web browser itself. Configuring Redis using a ConfigMap This page provides a real world example of how to configure Redis using a ConfigMap and builds upon the Configure Containers Using a ConfigMap task. ● Objectives ● Before you begin ● Real World Example: Configuring Redis using a ConfigMap ● What's next
Objectives ● Create a ConfigMap. ● Create a pod specification using the ConfigMap. ● Create the pod. ● Verify that the configuration was correctly applied.
Before you begin ● You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. If you do not already have a cluster, you can create one by using Minikube, or you can use one of these Kubernetes playgrounds: ● Katacoda ● Play with Kubernetes To check the version, enter kubectl version. ● Understand Configure Containers Using a ConfigMap.
Exposing an External IP Address to Access an Application in a Cluster This page shows how to create a Kubernetes Service object that exposes an external IP address.
● Objectives ● Before you begin ● Creating a service for an application running in five pods ● Cleaning up ● What's next
Objectives ● Run five instances of a Hello World application. ● Create a Service object that exposes an external IP address. ● Use the Service object to access the running application.
Before you begin ● Install kubectl. ● Use a cloud provider like Google Kubernetes Engine or Amazon Web Services to create a Kubernetes cluster. This tutorial creates an external load balancer, which requires a cloud provider. ● Configure kubectl to communicate with your Kubernetes API server. For instructions, see the documentation for your cloud provider. Example: Deploying PHP Guestbook application with Redis This tutorial shows you how to build and deploy a simple, multi-tier web application using Kubernetes and Docker. This example consists of the following components:
● A single-instance Redis master to store guestbook entries ● Multiple replicated Redis instances to serve reads ● Multiple web frontend instances ● Objectives ● Before you begin ● Start up the Redis Master ● Start up the Redis Slaves ● Set up and Expose the Guestbook Frontend ● Scale the Web Frontend ● Cleaning up ● What's next
Objectives ● Start up a Redis master. ● Start up Redis slaves. ● Start up the guestbook frontend. ● Expose and view the Frontend Service. ● Clean up. Here you can the Tutorial of Kubernetes
Before you begin
You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. If you do not already have a cluster, you can create one by using Minikube, or you can use one of these Kubernetes playgrounds: ● Katacoda ● Play with Kubernetes To check the version, enter kubectl version.
