## fleetlock
[fleetlock](https://github.com/poseidon/fleetlock) is a reboot coordinator for Fedora CoreOS nodes. It implements the [FleetLock](https://github.com/coreos/airlock/pull/1/files) protocol for use as a [Zincati](https://github.com/coreos/zincati) lock [strategy](https://github.com/coreos/zincati/blob/master/docs/usage/updates-strategy.md) backend.
Declare a Zincati `fleet_lock` strategy when provisioning Fedora CoreOS nodes via [snippets](/advanced/customization/#hosts).
```yaml
variant: fcos
version: 1.1.0
storage:
files:
- path: /etc/zincati/config.d/55-update-strategy.toml
contents:
inline: |
[updates]
strategy = "fleet_lock"
[updates.fleet_lock]
base_url = "http://10.3.0.15/"
```
```tf
module "nemo" {
...
controller_snippets = [
file("./snippets/zincati-strategy.yaml"),
]
worker_snippets = [
file("./snippets/zincati-strategy.yaml"),
]
}
```
Apply fleetlock based on the example manifests.
```sh
git clone git@github.com:poseidon/fleetlock.git
kubectl apply -f examples/k8s
```
