Dockerized jenkins install with docker in docker via ansible (dind)

Example of compose file:

version: '3'
services:
    jenkins:
        build:
            context: .
            dockerfile: Dockerfile-jenkins-docker
        container_name: jenkins-docker
        networks:
            - jenkins
        restart: always
        environment:
            - DOCKER_HOST=tcp://docker:2376
            - DOCKER_CERT_PATH=/certs/client
            - DOCKER_TLS_VERIFY=1
            # increase user session duration
            - JENKINS_OPTS=--sessionTimeout=1440 --sessionEviction=43200
        volumes:
            - jenkins-data:/var/jenkins_home
            - jenkins-docker-certs:/certs/client:ro
        ports:
            - 127.0.0.1:8080:8080

    jenkins-docker-executor:
        image: docker:dind
        container_name: jenkins-docker-executor
        environment:
            - DOCKER_TLS_CERTDIR=/certs
        networks:
            jenkins:
                aliases:
                    - docker
        restart: always
        privileged: True
        volumes:
            - jenkins-data:/var/jenkins_home
            - jenkins-docker-certs:/certs/client
        ports:
            - 127.0.0.1:2376:2376

networks:
    jenkins:
      driver: bridge

volumes:
    jenkins-data:
        driver: local
    jenkins-docker-certs:
        driver: local

As you can see we need a custom dockerfile (Dockerfile-jenkins-docker) which should look like:

FROM jenkins/jenkins:{{ jenkins_version }}
USER root
ENV TZ=Europe/Zagreb
RUN apt-get update && apt-get install -y lsb-release
RUN curl -fsSLo /usr/share/keyrings/docker-archive-keyring.asc \
  https://download.docker.com/linux/debian/gpg
RUN echo "deb [arch=$(dpkg --print-architecture) \
  signed-by=/usr/share/keyrings/docker-archive-keyring.asc] \
  https://download.docker.com/linux/debian \
  $(lsb_release -cs) stable" > /etc/apt/sources.list.d/docker.list
RUN apt-get update && apt-get install -y docker-ce-cli
USER jenkins

Add these 2 files to templates or files folder in ansible role and add a task similar to this:

...

- name: Copy docker compose file
  template:
      src: docker-compose.j2
      dest: /opt/jenkins-docker/docker-compose.yml
      mode: 0600

- name: Copy Jenkins docker Dockerfile
  template:
      src: Dockerfile-jenkins-docker.j2
      dest: /opt/jenkins-docker/Dockerfile-jenkins-docker
      mode: 0600

- name: Run compose command
  command:
      chdir: /opt/jenkins-docker
      cmd: docker-compose up --detach --build

...
