Create Jenkins pipeline : automated build and testing

• install jenkin with docker

• After installation,open configuration system. Check environement box and add both JAVA and ANDROID path to

• Click open Blueocean

• In Blueocean, we can create new pipeline by connecting github to it.

  • The token is generated in github-setting-develop setting-Personal access token Follow the links, it will select the necessary permissions: repo:status, public_repo, admin:repo_hook, read:user, user:email

  select repo for full access for private repositories

  • Choose a repo and create a basic pipeline, the pipeline is not working since a jenkinsfile is required for pipeline to define stages and run.

• List of stages, jenkins pipeline

  • link codes to check syntax
  • build the app
  • testing
  • deploy: blue/green, production, etc

Use jenkinsfile to define complete set of build, test , deploy steps.

    pipeline {
        agent any 
        stages {
            stage('Lint') {
                steps {
                    // Check for syntax Errors 
                   
                }   
            }
            stage('build') {
                steps {
                    // Run whatever commands that is necessary to build the application  and build the applicatoin
                    sh 'npm install' 
                    
                }

            stage('Push image') {
                steps {

            stage('set current kubectl context') {
                steps{
                   // set up kubect resources
