Integration with Git, Maven, Jenkins, Ansible, and Docker

Pre-Requisites:

1. Docker installed on ansible server

2. login to "docker hub" on ansible server

3. Create Jenkins job,

   • Source Code Management:
     • Repository : ``
     • Branches to build : */main
   • Build:
     • Root POM:pom.xml
     • Goals and options : clean install package
   • Post Steps

     • Send files or execute commands over SSH

       • Name: Ansible server
       • Source files : webapp/target/*.war
       • Remove prefix : webapp/target
       • Remote directory : //opt//docker

     • Send files or execute commands over SSH

       • Remote directory : //opt//docker
       • Exec Command:
         • cd /opt/docker
         • sudo docker build -t $JOB_NAME .
         • sudo docker tag $JOB_NAME sourabhmiraje/$JOB_NAME:$BUILD_ID
         • sudo docker tag $JOB_NAME sourabhmiraje/$JOB_NAME:latest
         • sudo docker push sourabhmiraje/$JOB_NAME:$BUILD_ID
         • sudo docker push sourabhmiraje/$JOB_NAME:latest
         • sudo docker rmi -f sourabhmiraje/$JOB_NAME:latest
         • sudo docker rmi -f sourabhmiraje/$JOB_NAME:$BUILD_ID
         • sudo docker rmi -f $JOB_NAME

Part-02 : Deploy Containers

1. Write a yaml file to create a container (file name : playbook.yaml)

     ---
     - hosts: docker
       tasks:
          - name: Stop a container
            community.docker.docker_container:
              name: myapp
              state: stopped
            ignore_errors: yes
   
          - name: Remove container from all networks
            community.docker.docker_container:
              name: myapp
              purge_networks: yes
            ignore_errors: yes
   
          - name: Remove image
            community.docker.docker_image:
              state: absent
              force_absent: yes
              name: sourabhmiraje/project_4
              tag: latest
            ignore_errors: yes
   
          - name: Start a container with a command
            community.docker.docker_container:
              name: myapp
              image: sourabhmiraje/project_4
              ports: 8090:8080
   

2. Run playbook on Ansible server.
   • Under post build actions
     • Send files or execute commands over SSH
       • Exec Command:

          cd /opt/playbooks
          ansible-playbook create_docker_container.yml
