In this tutorial, Quickstart with Jenkins in docker. Jenkins is an automation CI/CD tool. with Jenkins, you can create jobs to build, test and deploy your application. Docker the essential for DevOps Roles.

Set up Jenkins with docker

Docker compose for Jenkins

You can create “jenkins-docker-compose.yml” file for Jenkins

version: '2'

services:
  jenkins:
    image: 'jenkins:2.60.3'
    container_name: jenkins
    user: root
    restart: always
    ports:
      - '8080:8080'
      - '5000:5000'
    volumes:
      - /home/huupv/data/jenkins:/var/jenkins_home
      - /var/run/docker.sock:/var/run/docker.sock

Note:

• docker.sock with Host in the volume. But be careful, you can delete the container from Docker.
• “/var/jenkins_home” is a place to read docker images. so do not change. If Docker has died, then your data remains and restore if you start it again.

Starting Jenkins with docker

Execute this command as below

docker-compose -f jenkins-docker-compose.yml up

From local, you can access  Jenkins at browser at http://0.0.0.0:8080

Introduction

In this tutorial, you’ll learn how to set up WordPress using Docker Compose, which utilizes two separate containers to streamline the process. Docker is crucial for DevOps roles, enabling efficient deployment and management of applications. This guide simplifies the integration of WordPress into your Docker workflow, ensuring a smooth setup.

Docker image

• WordPress
• MySQL

You can find the installation guide for Docker Compose provided here

Docker compose WordPress

Docker Compose with WordPress refers to using Docker Compose as a tool to facilitate the setup and management of WordPress in a containerized environment. This approach leverages Docker to simplify the deployment and configuration processes by defining and running multi-container Docker applications. It’s a powerful method for developers looking to streamline their WordPress development and deployment workflows within Docker.

The configuration file and start docker-compose.

version '2'
services: 
 web:
  image: wordpress
  ports:
    - "8888:80"
  environment:
    WORDPRESS_DB_PASSWORD: password_here
    WORDPRESS_DB_HOST: db
 db:
  image: mysql
  environment:
    MYSQL_ROOT_PASSWORD: password_here

Starting docker in the background with the -d option.

$ docker-compose up -d

After, you can check http://localhost:8888 in the browser.

The end service is down to the command below

$ docker-compose down
