    device-mapper-persistent-data \
    lvm2
    
  $ sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

  $ sudo yum -y install docker-ce docker-ce-cli containerd.io
    
  $ systemctl start docker
  $ systemctl enable docker
  $ systemctl status docker
    
  $ usermod -aG docker nanox
  

• Install Docker Compose

  $ sudo curl -L "https://github.com/docker/compose/releases/download/1.25.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
    
  $ chmod +x /usr/local/bin/docker-compose
  $ docker-compose -v
  

• Download jenkins docker image

  $ docker pull jenkins/jenkins
    
  $ docker info | grep -i root
   Docker Root Dir: /var/lib/docker
    
  $ du -sh /var/lib/docker
  586M	/var/lib/docker
  

• Create a docker compose file for jenkins

  $ mkdir jenkins-data
  $ mkdir jenkins_home
  $ cd jenkins-data
  $ vi docker-compose.yml
  ...
  version: '3'
  services:
    jenkins:
      container_name: jenkins
      image: jenkins/jenkins
      ports:
        - "8080:8080"
      volumes:
        - $PWD/jenkins_home:/var/jenkins_home
      networks:
        - net
  networks:
    net:
    ...
  

• Create a docker container for jenkins

  $ sudo chown 1000:1000 jenkins_home -R
  $ docker-compose up -d
  $ docker ps
  CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                               NAMES
  cdcd15d0b313        jenkins/jenkins     "/sbin/tini -- /usr/…"   21 seconds ago      Up 19 seconds       0.0.0.0:8080->8080/tcp, 50000/tcp   jenkins
    
  $ docker logs -f jenkins
