# hcloud-docker
Provides a Docker image with the Hetzner Cloud CLI pre-installed.
## Starting a GitLab CI runner
This image was created to start one or more GitLab CI runners on Hetzner Cloud on demand.
The following .gitlab-ci.yml demonstrates how it can be used:
```
variables:
HCLOUD_ARM64_SERVER: cax31
HCLOUD_AMD64_SERVER: cpx41
HCLOUD_LOCATION: ash
HCLOUD_IMAGE: ubuntu-22.04
HCLOUD_LABEL: type=ci-runner
Start runner:
image:
name: micheljung/hcloud:latest
entrypoint: [""]
stage: start-runners
only:
- branches
- tags
# Don't clone the git repository
variables:
GIT_STRATEGY: none
# Don't download caches
cache: []
parallel:
matrix:
- ARCH: arm64
GITLAB_RUNNER_TOKEN: $GITLAB_NATIVE_ARM64_CI_RUNNER_TOKEN
HCLOUD_SERVER_TYPE: $HCLOUD_ARM64_SERVER
- ARCH: amd64
GITLAB_RUNNER_TOKEN: $GITLAB_NATIVE_AMD64_CI_RUNNER_TOKEN
HCLOUD_SERVER_TYPE: $HCLOUD_AMD64_SERVER
script:
- |
hcloud server list | grep "gitlab-$ARCH-runner" || \
envsubst < .ci-cloudinit.yml | \
hcloud server create \
--name "gitlab-$ARCH-runner" \
--location $HCLOUD_LOCATION \
--type $HCLOUD_SERVER_TYPE \
--image $HCLOUD_IMAGE \
--label $HCLOUD_LABEL \
--label "arch=$ARCH" \
--user-data-from-file -
```
Your `.ci-cloudinit.yml` could look like this:
```yaml
#cloud-config
package_update: true
package_upgrade: true
packages:
- apt-transport-https
- ca-certificates
- curl
- gnupg
- lsb-release
- unattended-upgrades
runcmd:
- mkdir -p /etc/apt/keyrings
- curl -fsSL https://download.docker.com/linux/ubuntu/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
- echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | tee /etc/apt/sources.list.d/docker.list > /dev/null
- apt-get update
- apt-get install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin
- systemctl enable docker
- systemctl start docker
- docker run --rm -v gitlab-runner:/etc/gitlab-runner gitlab/gitlab-runner register --non-interactive --executor "docker" --url "https://gitlab.com/" --docker-image docker:latest --docker-volumes /var/run/docker.sock:/var/run/docker.sock --token "$GITLAB_RUNNER_TOKEN"
- docker run -d --restart unless-stopped --name gitlab-runner -v /var/run/docker.sock:/var/run/docker.sock -v gitlab-runner:/etc/gitlab-runner gitlab/gitlab-runner
