Script: How to write a bash script to run CI pipeline commands for development?

In my previous post — CI: How to run docker test on a Node.js project in Jenkins? we have the docker commands arranged in the two stages in CI (Jenkins),

1. Build
2. Test

The Jenkinsfile of the Node.js project

pipeline {
    agent any
    stages {
        stage('Checkout') {
            steps {
                git branch: 'main', changelog: false, poll: false, url: 'https://github.com/akarsh/Selenium-WebDriver-CucumberJS-example-project.git'
            }
        }
        stage('Build') {
            steps {
                sh '''
                docker build -t example-project --target test . 
                '''
            }
        }
        stage('Run test') {
            steps {
                sh'''
                docker run --rm --name cucumber-test example-project 
                '''
            }
        }
    }
}

How about we are able to run the two stages in development when we are working on a local branch?

This can be achieved by adding the two docker commands in a bash script file.

Create a bash script file and name it as init.sh and add the commands from the two stages,

The bash script for development purpose of the Node.js project

#!/bin/bash
# Build
docker build -t example-project --target test .
#Test
docker run --rm --name cucumber-test example-project

Run the bash script file using the following command,

sh init.sh

It will execute the two commands locally in the terminal.

Note: Make sure DockerDesktop app is running before running the bash script.

I hope my article helps you understand how to write a bash script to run CI pipeline commands for development.
