Jenkins

Jenkins is a essential automation tool to setup Continuous Integration. Its the integrator which helps you build your development, testing and deployment workflow and create job pipelines. It also adds visibility to all stake holders including the Dev, QA, Ops teams involved in building, testing and deploying the product.

JFrog Artifactory

Setting up CI-CD Environment with Docker-Compose

This is the easiest method to setup Jenkins and is a recommended option.

Installing Docker Engine and Docker-Compose

Proceed with installing Docker Engine and docker-compose on your choice of Operating System. For details on how to install docker visit the official installation page at
docker engine
docker-compose

We assume you have installed docker, docker-compose and are ready to launch containers before proceeding. To validate docker environment run.

docker ps

If the above command goes through without errors, you are all set.

Running Jenkins and Artifactory using Docker-Compose

Once you all set, now you can create compose file for Jenkins and Artifactory. This is the simplest way of installing Jenkins, Artifactory and requires minimal efforts.

docker-compose-CI-CD.yml

version: '2'

networks:
  custom:
    driver: bridge
    ipam:
      driver: default
      config:
        - subnet: 192.168.61.0/28
services:
  jenkins:
    image: jenkins
    ports:
      - "8080:8080"
      - "50000:50000"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"
    networks:
      custom:
        ipv4_address: 192.168.61.4
    domainname: codespaces.io
    hostname: jenkins
    restart: always
  artifactory:
    image: docker.bintray.io/jfrog/artifactory-oss
    ports:
      - "8081:8081"
    networks:
      custom:
        ipv4_address: 192.168.61.5
    domainname: codespaces.io
    hostname: artifactory
    restart: always

Once you are ready with compose file, run below command to make it running

docker-compose -f docker-compose-CI-CD.yml up -d

If you install it using the instructions above, find out the IP address and go to http://YOUR_IP_ADDRESS:8080 to access jenkins UI http://YOUR_IP_ADDRESS:8081 to access artifactory UI

To start/stop containers with docker, use the following commands,

docker start [container-id]
docker stop [container-id]
