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
...
Tested on
- Debian 11
- Docker Compose version v2.6.0
- ansible 2.9.27
