How To Install And Setup Jenkins CI With Docker

0 Comments

Jenkins is one of the leading open-source automation servers and has been adopted by top industries around the globe to automate and deliver their software to market securely and in record times. It has a huge community that supports and provides hundreds of integrations and plugins that can be utilized to develop and build out your CICD pipelines. Let's have a look at how we can setup Jenkins CI with Docker:

Docker Compose Config And Jenkins Setup

The first is going to be to create our docker-compose YAML file and copy the code below:

version: "3.8"
services:
  jenkins:
    image: jenkins/jenkins:lts
    restart: always
    privileged: true
    user: root
    ports:
      - 5000:8080
      - 50000:50000
    container_name: jenkins
    volumes:
      - /docker/jenkins:/var/jenkins_home
      - /var/run/docker.sock:/var/run/docker.sock

Once you created the docker-compose yaml run docker-compose up -d to set up Jenkins. After the setup is completed navigate to http://<docker_host_ip>:5000 and it will prompt you for the administrator password like in the image below. If you have Portainer set up you can view the docker logs of your Jenkins service there otherwise run docker logs jenkins to view and copy the administrator password to continue with the setup.

The next step is to select the plugins you want to install. For this exercise we selected suggested plugins, alternative plugins can always be installed at a later stage. The installation of suggested plugins will install and once complete you will be able to create your login credentials and login to the Jenkins dashboard and start scripting and building out CI/CD pipelines and workflows.
