## Install Debian
We recommend Debian Bullseye
## Install Docker CE from docker.io
Do not use the docker engine shipped by Debian
Doc:
- https://docs.docker.com/engine/install/debian/
- https://docs.docker.com/compose/install/
On a fresh install, as root:
```bash
apt-get remove -y docker docker-engine docker.io containerd runc
apt-get update
apt-get install apt-transport-https ca-certificates curl gnupg lsb-release
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian $(lsb_release -cs) stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null
apt-get update
apt-get install -y docker-ce docker-ce-cli containerd.io
curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
```
## Install the runner
*This is our Nix runner version 2, previously we had another way to start Nix runners. This one has a proper way to handle concurrency, require less boilerplate, and should be safer and more idiomatic.*
```bash
wget https://git.deuxfleurs.fr/Deuxfleurs/infrastructure/raw/branch/main/app/drone-ci/integration/nix.conf
wget https://git.deuxfleurs.fr/Deuxfleurs/infrastructure/raw/branch/main/app/drone-ci/integration/docker-compose.yml
# Edit the docker-compose.yml to adapt its variables to your needs,
# especially the capacitiy value and its name.
COMPOSE_PROJECT_NAME=drone DRONE_SECRET=xxx docker-compose up -d
```
That's all folks.
## Check if a given job is built by your runner
```bash
export URL=https://drone.deuxfleurs.fr
export REPO=Deuxfleurs/garage
export BUILD=1312
curl ${URL}/api/repos/${REPO}/builds/${BUILD} \
| jq -c '[.stages[] | { name: .name, machine: .machine }]'
```
It will give you the following result:
```json
[{"name":"default","machine":"1686a"},{"name":"release-linux-x86_64","machine":"vimaire"},{"name":"release-linux-i686","machine":"carcajou"},{"name":"release-linux-aarch64","machine":"caribou"},{"name":"release-linux-armv6l","machine":"cariacou"},{"name":"refresh-release-page","machine":null}]
```
## Random note
*This part might be deprecated!*
This setup is done mainly to allow nix builds with some cache.
To use the cache in Drone, you must set your repository as trusted.
The command line tool does not work (it says it successfully set your repository as trusted but it did nothing):
the only way to set your repository as trusted is to connect on the DB and set the `repo_trusted` field of your repo to true.
