Docker image for keepalived to failover Floating-IPs (of Hetzner Cloud).

* Includes helper scripts to check and handle Floating-IPs

  * `assign-floating-ip.sh`: Assigns a Floating-IP to the current Node

  * `check-fip.sh`: Checks if a Floating-IP is assigned to the current Node

  * `check-http.sh`: Simple HTTP-Check to validate if the upstream proxy is healthy

  * `check-enabled.sh`: Script which fails if `ENABLED=0` is defined to manually put Keepalived in FAULT-mode.

* Includes [prometheus exporter](https://github.com/cafebazaar/keepalived-exporter) (Port 9165)

* Redirects script-outputs to stdout/stderr

## Usage

* Create your [docs/keepalived.conf](keepalived.conf) scripts and mount it to `/etc/keepalived`

* Run the Container/Pod with `HCLOUD_TOKEN` environment variable or (better) put the token in `/etc/keepalived/HCLOUD_TOKEN` secrets file.

* Optional: Configure keepalived-exporter using env-vars

  * `DISABLE_EXPORTER=false`: Set `true` to disable the exporter.

  * `EXPORTER_LISTEN_ADDRESS=:9165`: Listen address/port for prometheus exporter.
