Kubectl Kustomize : Hello World

The aim of this project is to deploy an Hello World application on Kubernetes instance like Minikube thanks to the Kustomize Kubectl option.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

What things you need to deploy the application :

• Kubectl must be installed on your computer (version >= 1.14.0)
• Minikube must be installed on your computer

Usage

Be aware that you need to be in the root directory of the project to be able to run the commands.

Deployment

To deploy development Hello World application on Minikube instance, just run this command :

$ kubectl apply -k overlays/dev

If everything run as expected, you should be able to list the Kubernetes objects created :

$ kubectl get all -n dev-myhelloworld
NAME                                      READY   STATUS    RESTARTS   AGE
pod/dev-the-deployment-76dcc8f485-sm2pd   1/1     Running   0          19s


NAME                      TYPE           CLUSTER-IP       EXTERNAL-IP   PORT(S)          AGE
service/dev-the-service   LoadBalancer   10.107.181.141   <pending>     8666:32277/TCP   19s


NAME                                 READY   UP-TO-DATE   AVAILABLE   AGE
deployment.apps/dev-the-deployment   1/1     1            1           19s

NAME                                            DESIRED   CURRENT   READY   AGE
replicaset.apps/dev-the-deployment-76dcc8f485   1         1         1       19s

To access the Hello World application with your browser, you need to get the Minikube IP in command line :

$ minikube IP
192.168.99.100

If everything run has expected, you should access the Hello World application on the LoadBalancer port : http://192.168.99.100:32277/

Destroy

To destroy the Kubernetes objects created, just run this command :

$ kubectl delete -k overlays/dev
