Hi everyone, this article takes you through building a simple react static app using Jenkins.

Step 1 : I create a folder with name : laravel-app

composer create-project laravel/laravel laravel-app

Step 2 : I create a file Dockfile in folder laravel-app

cd laravel-app

nano Dockerfile

FROM php:8.1-fpm

# Set working directory
WORKDIR /var/www

# Add docker php ext repo
ADD https://github.com/mlocati/docker-php-extension-installer/releases/latest/download/install-php-extensions /usr/local/bin/

# Install php extensions
RUN chmod +x /usr/local/bin/install-php-extensions && sync && \
    install-php-extensions mbstring pdo_mysql zip exif pcntl gd memcached

# Install dependencies
RUN apt-get update && apt-get install -y \
    build-essential \
    libpng-dev \
    libjpeg62-turbo-dev \
    libfreetype6-dev \
    locales \

# Install supervisor
RUN apt-get install -y supervisor

# Install composer
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

# Clear cache
RUN apt-get clean && rm -rf /var/lib/apt/lists/*

# Add user for laravel application
RUN groupadd -g 1000 www
RUN useradd -u 1000 -ms /bin/bash -g www www

# Copy code to /var/www
COPY --chown=www:www-data . /var/www

# add root to www group
RUN chmod -R ug+w /var/www/storage

# Copy nginx/php/supervisor configs
RUN cp docker/supervisor.conf /etc/supervisord.conf
RUN cp docker/php.ini /usr/local/etc/php/conf.d/app.ini
RUN cp docker/nginx.conf /etc/nginx/sites-enabled/default

# PHP Error Log Files
RUN mkdir /var/log/php
RUN touch /var/log/php/errors.log && chmod 777 /var/log/php/errors.log

# Deployment steps
RUN composer install --optimize-autoloader --no-dev
RUN chmod +x /var/www/docker/run.sh

EXPOSE 80
ENTRYPOINT ["/var/www/docker/run.sh"]

Step 3 : I create a file Jenkinsfile

nano Jenkinsfile

pipeline {
    agent any
    environment {
        DOCKERHUB_CREDENTIALS = credentials('dockerhub')
    }
    stages {
        stage('Clone') {
            steps {
                git branch: 'develop', credentialsId: 'github', url: 'https://github.com/khaitk/laravel-docker-jenkins.git'
            }
        }

        stage('Build Docker Image') {         
            steps{                
                sh 'docker build -t khraiteka/laravel-jenkins-docker:$BUILD_NUMBER .'           
                echo 'Build Image Completed'                
            }           
        }

        stage('Login') {
            steps {
                sh 'echo $DOCKERHUB_CREDENTIALS_PSW | docker login -u $DOCKERHUB_CREDENTIALS_USR --password-stdin'
            }
        }
        stage('Push') {
            steps {
                sh 'docker push khraiteka/laravel-jenkins-docker:$BUILD_NUMBER'
                echo 'Push Image Completed' 
            }
        }
    }
    post {
        failure {
              mail to: 'khaitkdev@gmail.com',
                subject: "FAILED: Build ${env.JOB_NAME}", 
                body: "Build failed ${env.JOB_NAME} build no: ${env.BUILD_NUMBER}.\n\nView the log at:\n ${env.BUILD_URL}\n\nURL:\n${env.RUN_DISPLAY_URL}"
        }
    
    success{
            mail to: 'khaitkdev@gmail.com',
                subject: "SUCCESSFUL: Build ${env.JOB_NAME}", 
                body: "Build Successful ${env.JOB_NAME} build no: ${env.BUILD_NUMBER}\n\nView the log at:\n ${env.BUILD_URL}\n\nURL:\n${env.RUN_DISPLAY_URL}"
        }
        
        aborted{
            mail to: 'khaitkdev@gmail.com',
                subject: "ABORTED: Build ${env.JOB_NAME}", 
                body: "Build was aborted ${env.JOB_NAME} build no: ${env.BUILD_NUMBER}\n\nView the log at:\n ${env.BUILD_URL}\n\nURL:\n${env.RUN_DISPLAY_URL}"
        }
    }
