A special note to ETNA's students is available at the bottom of the README.
Setup a CI/CD infrastructure with the following components:
- Gitlab
- Gitlab-runner
- Docker in swarm mode
- A monitoring stack (supposedly a TICK stack, but prometheus/grafana/node_exporter will be our go-to)
- Traefik
The code itself will be hosted on the private gitlab server and will trigger unit test and fonctionnal tests upon push. If the code is validated, it will trigger a blue/green deployment in "production"
The registration token is located in gitlab.yml.
In order to use it in the gitlab_runner role, provide the flag -e @vars/gitlab.yml and decrypt it using the ansible-vault secret while executing the playbook.
- install_gitlab
In order to configure the users, you will need to provide a
gitlab_tokenand a list of users.ansible-playbook -i inventory.yml -e @vars/users.yml gitlab.yml - gitlab_runner
- setup_net_fs - Install and configure GlusterFS
- setup_local_domain_name - Install and configure dnsmasq

If you ended up finding this public project, congrats and welcome !
First of all, feel free to leave a ⭐ if you liked my implementation.
One tiny point to keep in mind if you're currently doing the SPE-CLO5 module: I am still a teacher at ETNA's and I might end up reviewing your project. The School's staff is aware of this repository and I don't want any of you to get into trouble because you were a bit curious ! Think twice before "getting inspired" by the implementation made by someone that might end up grading your work. 😉
