5 It is possible to deploy etcd with three methods. To change the default deployment method (host), use the `etcd_deployment_type` variable. Possible values are `host`, `kubeadm`, and `docker`.
9 Host deployment is the default method. Using this method will result in etcd installed as a systemd service.
13 Installs docker in etcd group members and runs etcd on docker containers. Only usable when `container_manager` is set to `docker`.
17 This deployment method is experimental and is only available for new deployments. This deploys etcd as a static pod in master hosts.
21 To expose metrics on a separate HTTP port, define it in the inventory with:
24 etcd_metrics_port: 2381
27 To create a service `etcd-metrics` and associated endpoints in the `kube-system` namespace,
28 define it's labels in the inventory with:
31 etcd_metrics_service_labels:
33 app.kubernetes.io/managed-by: Kubespray
34 app: kube-prometheus-stack-kube-etcd
35 release: prometheus-stack
38 The last two labels in the above example allows to scrape the metrics from the

40 chart with the following Helm `values.yaml` :
