This repository contains scripts to launch GitLab Runners for your group.
Once configured, GitLab runners are called by the GitLab server to perform computations (package, building, test, etc) on you code, after each commit. Runners are not executed on the server but on remote computer accessible by the network.
This repository contains various scripts to initialise a GitLab Runner, to register it for your group with the GitLab server, and to launch it.
## Getting Started
These instructions will get you a copy of the project up and running on your local machine
### Prerequisites
You need the registration token for your group from the GitLab server.
For this go to your group page, **settings**, **CI/CD** and **Runners settings**. For the LBMC group, this correspond to the following url :
First, we need to build a custom container of the gitlab-runner with the following command.
```sh
sudo mkdir-p /srv/gitlab-runner/config
gitlab_runner/docker_init.sh
```
This will build the `gitlab_runner` container with the certificate of the [gitlab.biologie.ens-lyon.fr](https://gitlab.biologie.ens-lyon.fr/) website installed.
This container, will be the process that register and manage the GitLab runners on your computer.
To run safely the runners themselves, we are going to instantiate new container, for each runners.
For example to have a runner for `R` development :
```sh
r_dev/docker_init.sh
```
The `gitlab_runner` container will be able to launch a runner within the `r_dev:3.5.1` container.
## Registering a Runner
To register a runner you need to use the `*_runner_register.sh` scripts.
For a `r_dev:3.5.1` runner, edit the `r_dev_runner_register.sh` file to add your group token.
Specify the tag and the name of the runner and register it with the following command:
```sh
./r_dev_runner_register.sh
```
You can check the runners registered in the **CI/CD** settings of your group.
## Launching your Runners
To launch your runners execute the following command:
```sh
./runner_launch.sh
```
To check the GitLab runner status:
```sh
docker ps
```
## Sopping your Runners
To stop your runners, execute the following command:
```sh
./runner_stop.sh
```
