Install-and-Run-Jenkins-With-Docker-Compose

install install Jenkins as container on ubuntu

On ubuntu server, first install docker and docker-compose

sudo apt-get update
sudo apt-get install docker.io
sudo systemctl start docker
sudo systemctl status docker
sudo apt  install docker-compose

then, create docker-compose.yaml

touch docker-compose.yaml 
vi docker-compose.yaml 

here is the contex of the yaml file:

      1 #docker-compose.yaml
      2 version: '3.8'
      3 services:
      4   jenkins:
      5   image: jenkins/jenkins:lts
      6    privileged: true
      7    user: root
      8    ports:
      9     - 8080:8080
      10     - 50000:50000
      11    container_name: jenkins
      12    volumes:
      13    - /home/ubuntu/jenkins/jenkins_configuration:/var/jenkins_home
      14    - /var/run/docker.sock:/var/run/docker.sock

this yaml file will get the lastest version of the jenkins as : mage: jenkins/jenkins:lts

set ports, and volumes.

• Line #1 is a comment.

• Line #2 tells Docker Compose which version of the Compose specification we’re using.

• Line #3 starts defining services. For now, we just have one.

The rest of the file defines the Jenkins container.

• It will run the latest Jenkins image with root privileges. We’re running the container with host networking, so lines #9 and #10 tell Docker to redirect ports 8080 and 50000 to the host’s network.

The container’s name is jenkins.

• Finally, /home/${myname}/jenkins_compose/jenkins_configuration is mapped to /var/jenkins_home in the container.

Run docker-compose in the directory where you placed docker-compose.yaml.

  $ docker-compose up -d

Now point a web browser at port 8080 on your host system. You’ll see the unlock page.

    $ docker logs jenkins | less
