# woodpecker-autoscaler
|
|
|
|
[](https://woodpecker.uploadfilter24.eu/repos/8)
|
|
|
|
Dynamically spawns woodpecker ci build agents in hetzner cloud.
|
|
|
|
## Installing with Helm
|
|
|
|
The deployment will use helm and the chart in `chart/woodpecker-autoscaler`.
|
|
You will need a [hcloud api token](https://docs.hetzner.com/cloud/api/getting-started/generating-api-token/), a [woodpecker agent secret](https://woodpecker-ci.org/docs/administration/agent-config#woodpecker_agent_secret), a woodpecker api token and a definition of the build agents to be created.
|
|
Expose these information to the floater as described in this example:
|
|
|
|
```yaml
|
|
env:
|
|
- name: WOODPECKER_AUTOSCALER_LOGLEVEL
|
|
value: "Info"
|
|
- name: WOODPECKER_AUTOSCALER_CHECK_INTERVAL
|
|
value: "15"
|
|
- name: WOODPECKER_AUTOSCALER_WOODPECKER_LABEL_SELECTOR
|
|
value: "uploadfilter24.eu/instance-role=Woodpecker"
|
|
- name: WOODPECKER_AUTOSCALER_WOODPECKER_INSTANCE
|
|
value: "define_it"
|
|
- name: WOODPECKER_AUTOSCALER_WOODPECKER_AGENT_SECRET
|
|
value: "define_it"
|
|
- name: WOODPECKER_AUTOSCALER_WOODPECKER_API_TOKEN
|
|
value: "define_it"
|
|
- name: WOODPECKER_AUTOSCALER_HCLOUD_TOKEN
|
|
value: "define_it"
|
|
- name: WOODPECKER_AUTOSCALER_HCLOUD_INSTANCE_TYPE
|
|
value: "cpx21"
|
|
- name: WOODPECKER_AUTOSCALER_HCLOUD_LOCATION
|
|
value: "define_it"
|
|
- name: WOODPECKER_AUTOSCALER_HCLOUD_SSH_KEY
|
|
value: "define_it"
|
|
```
|
|
|
|
you can also create a secret manually with these information and reference the existing secret like this in the `values.yaml`:
|
|
|
|
```yaml
|
|
externalConfigSecret:
|
|
enabled: true
|
|
name: "my-existing-secret"
|
|
```
|
|
|
|
Now you are able to deploy:
|
|
|
|
```bash
|
|
kubectl create namespace woodpecker-autoscaler
|
|
cd chart/woodpecker-autoscaler
|
|
helm upgrade --install -f values.yaml -n woodpecker-autoscaler woodpecker-autoscaler ./
|
|
```
|
|
|
|
## Installing Manually
|
|
|
|
Download the binary from the release section and place it somewhere on your system; `/usr/bin/woodpecker-autoscaler` for example.
|
|
Create a systemd service like the one in this template:
|
|
|
|
```systemd
|
|
[Unit]
|
|
Description=Dynamically spawn woodpecker ci build agents in hetzner cloud
|
|
|
|
[Service]
|
|
Type=simple
|
|
Nice=10
|
|
ExecStart=/usr/bin/woodpecker-autoscaler
|
|
EnvironmentFile="/etc/default/woodpecker-autoscaler.env"
|
|
```
|
|
|
|
Now place the environment variable configuration in the specified file:
|
|
|
|
```bash
|
|
WOODPECKER_AUTOSCALER_LOGLEVEL=Info
|
|
WOODPECKER_AUTOSCALER_CHECK_INTERVAL=15
|
|
WOODPECKER_AUTOSCALER_WOODPECKER_LABEL_SELECTOR="uploadfilter24.eu/instance-role=Woodpecker"
|
|
WOODPECKER_AUTOSCALER_WOODPECKER_INSTANCE="define_it"
|
|
WOODPECKER_AUTOSCALER_WOODPECKER_AGENT_SECRET="define_it"
|
|
WOODPECKER_AUTOSCALER_WOODPECKER_API_TOKEN="define_it"
|
|
WOODPECKER_AUTOSCALER_HCLOUD_TOKEN="define_it"
|
|
WOODPECKER_AUTOSCALER_HCLOUD_INSTANCE_TYPE=cpx21
|
|
WOODPECKER_AUTOSCALER_HCLOUD_LOCATION="define_it"
|
|
WOODPECKER_AUTOSCALER_HCLOUD_SSH_KEY="define_it"
|
|
```
|
|
|
|
Now reload the systemd daemons and start the service:
|
|
|
|
```bash
|
|
sudo systemctl daemon-reload
|
|
sudo systemctl enable woodpecker-autoscaler
|
|
sudo systemctl start woodpecker-autoscaler
|
|
```
