Rest Data Spring a simple project using spring boot.

objectives

• build a pipeline to dockerize Jenkins on port 8090 (host side)
• using docker installed on the host machine
• creating a Free Style pipeline with the help of a few plugins to:
  • build an image of the project using docker
  • push image to docker hub
  • run a docker container with the new image

Instructions:

• clone repository
• build the jenkins image with dockerfile available in Instruction folder
• open a terminal and go to cloned repository on you machine then to Instructions folder
• run docker build -t jenkins11 . notice: the period at the end is part of the code
• run docker run -d -it -u root -p 8090:8080 -p 50000:50000 --name jenkins_container -v jenkins_home:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock --restart unless-stopped jenkins11
• in case of macOS run docker run -d -it -u root -p 8090:8080 -p 50000:50000 --name jenkins_container -v jenkins_home:/var/jenkins_home -v /var/run/docker.sock.raw:/var/run/docker.sock --restart unless-stopped jenkins11
• once the container runs for the first time a temporary password is printed in the logs
• open a browser and goto localhost:8090 a greeting from jenkins asking for the temporary password
• navigate to Manage Jenkins > Global Tool Configuration > Maven > Add Maven > select the latest version of maven > Save
• navigate to Manage Jenkins > Manage Plugins > click tap Available > search for docker
• install the list of plugins:
  • CloudBees Docker Build and Publish plugin
  • Docker Pipeline
  • Docker Plugins
  • Docker API Plugin (usually installed already)
  • Docker Commons Plugin (usually installed already)

Important step

• open a terminal run docker exec -it -u root jenkins_container bash

• Now you are login as root for the container jenkins_container

• run docker logout

• run docker login

• enter docker hub credentials

• in jenkins navigate to new item > Freestyle project

• follow screenshot freestylejob

• To add SonarQube

• run docker network create jenkins

• run docker network connect jenkins {jenkins container name}

• run docker run -d --network=jenkins -p 9000:9000 --name sonarqube -e SOANR_ES_BOOTSTRP_CHECK_DISABLE=true sonarqube after configuring sonar qube go to jenkins pipeline and add build step invoke top-level Maven target goal sonar:sonar -Dsonar.projectKey={projectname_in_sonar} -Dsonar.host.url=http://sonarqube:9000 -Dsonar.login={TOKEN}

• username and password for sonarqube admin and admin
