Setup an Ubuntu OVH instance for CI

Create an Ubuntu 23.04 instance on OVH. You will have to provide a SSH key during the instance creation process.

First, install Docker: follow Install Docker Engine on Ubuntu instructions.

Pull the docker image:

docker pull nvidia/cuda:12.2.0-devel-ubuntu22.04

Second, install Gitlab-runner: follow Install GitLab Runner using the official GitLab repositories instructions.

Register the runner using the informations provided in the "Runners" section in Gitlab project "Settings" -> "CI/CD":

sudo gitlab-runner register

Fill in static_analysis,docker for the tag, docker for the executor and just copy-past the example for the default Docker image.

Edit the /etc/gitlab-runner/config.toml to increase the number of concurrent jobs (first line) to match at least the number of vcores.

🚧 Install CUDA GPU drivers, will probably require to change the Docker installation procedure to install the NVidia GPU-capable Docker engine...
