README
# SPE-CLO5
A [special note to ETNA's students](#special-note) is available at the bottom of the README.
## Goal
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"
## Ansible roles
### Docker-related
- [docker\_swarm](./roles/docker_swarm/README.md)
- [docker\_registry](./roles/docker_registry/README.md)
- [docker\_monitoring](./roles/docker_monitoring/README.md)
### Gitlab-related
The registration token is located in [gitlab.yml](./vars/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](./roles/install_gitlab/README.md)
In order to configure the users, you will need to provide a `gitlab_token` and a list of users.
`ansible-playbook -i inventory.yml -e @vars/users.yml gitlab.yml`
- [gitlab\_runner](./roles/gitlab_runner/README.md)
### Utility roles
- [setup\_net\_fs](./roles/setup_net_fs/README.md) - Install and configure GlusterFS
- [setup\_local\_domain\_name](./roles/setup_local_domain_name/README.md) - Install and configure dnsmasq

## Special note
If you ended up finding this _public_ project, congrats and welcome !
First of all, feel free to leave a :star: 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. :wink:
