This document provides an overview of hands-on training for using Jenkins X (JX), an automated CI/CD solution for building and deploying modern cloud applications on Kubernetes. It outlines prerequisites, and steps to install JX, create a Kubernetes cluster on GKE, and build a sample Spring Boot application with CI/CD pipelines and GitOps promotion between environments. It also discusses using Minikube for local development and provides additional references on JX and related tools.

16. Step 1. Install Jx
● https://jenkins-x.io/getting-started/install/

17. Step 2. Create Cluster GKE
● https://console.cloud.google.com/
● 먼저 Google Cloud 에 가입 후 프로젝트를 생성 한다.
○ ex: jenkinsx-dev
● https://jenkins-x.io/commands/jx_create_cluster/
● https://jenkins-x.io/commands/jx_create_cluster_gke/
● https://jenkins-x.io/demos/create_cluster_gke/
$ jx create cluster gke --cluster-name myk8scluster

18. Step 2. Create Cluster GKE
$ jx create cluster gke --cluster-name myk8scluster
--default-admin-password admin123!
? Google Cloud Zone: asia-northeast1-a
? Google Cloud Machine Type: n1-standard-2
$ jx get build logs
$ jx get apps

● http://jenkins-x.io/developing/browsing/
● How to create a new Spring Boot application with CI / CD and GitOps
Promotion
$ jx create spring -d web -d actuator
$ jx get build logs
$ jx get apps
Step 3. Create Cloud App

20. $ jx open --env staging
$ cd demo && jx create issue -t 'add a homepage'
$ git checkout -b wip
$ git add src
$ git commit -a -m 'add a homepage fixes #1'
$ git push origin wip
$ brew install hub
$ hub pull-request
Step 3. Create Cloud App

21. Step 3. Create Cloud App
$ jx env
dev
$ jx get build logs
$ jx get apps
$ jx promote --version 0.0.2 --env production --timeout 1h
$ jx get apps
$ jx env
$ jx open

22. Install Minikube
● https://kubernetes.io/docs/tasks/tools/install-minikube/
