+If you want a higher level of automation, easier configuration, automated cleanup of stopped Tailscale devices, or a mechanism for exposing the [Kubernetes API](https://kubernetes.io/docs/concepts/overview/kubernetes-api/) server to the tailnet, take a look at [Tailscale Kubernetes operator](https://tailscale.com/kb/1236/kubernetes-operator).

+## Multiple replicas

+Note that if you want to use the `Pod` manifests generated by the commands above in a multi-replica setup (i.e a multi-replica `StatefulSet`) you will need to change the mechanism for storing tailscale state to ensure that multiple replicas are not attemting to use a single Kubernetes `Secret` to store their individual states.

+### Option 1: storing in an `emptyDir`
+
+You can mount an [`emptyDir` volume](https://kubernetes.io/docs/concepts/storage/volumes/#emptydir) and configure the mount as the tailscale state store via `TS_STATE_DIR` env var. 
+You must also set `TS_KUBE_SECRET` to an empty string.
+
+An example:
+
+```yaml
+kind: StatefulSet
+metadata:
+  name: subnetrouter
+spec:
+  replicas: 2
+  ...
+  template:
+    ...
+    spec:
+      ...
+      volumes:
+      - name: tsstate
+        emptyDir: {}
+      containers:
+      - name: tailscale
+        env:
+        - name: TS_STATE_DIR
+          value: /tsstate
+        - name: TS_KUBE_SECRET
+          value: ""
+        volumeMounts:
+        - name: tsstate
+          mountPath: /tsstate
+```
+
+The downside of this approach is that the state will be lost when a `Pod` is
+deleted. In practice this means that when you, for example, upgrade proxy
+versions you will get a new set of Tailscale devices with different hostnames.
+
+### Option 2: dynamically generating unique `Secret` names
+
+If you run the proxy as a `StatefulSet`, the `Pod`s get [stable identifiers](https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/#stable-network-id).
+You can use that to pass an individual, static state `Secret` name to each proxy:
+
+```yaml
+kind: StatefulSet
+metadata:
+  name: subnetrouter
+spec:
+  replicas: 2
+  ...
+  template:
+    ...
+    spec:
+      ...
+       containers:
+      - name: tailscale
+        env:
+        - name: TS_KUBE_SECRET
+          valueFrom:
+            fieldRef:
+              apiVersion: v1
+              fieldPath: metadata.name
+```
+
+In this case, each replica will store its state in a `Secret` named the same as the `Pod` and as `Pod` names for a `StatefulSet` do not change if `Pod`s get recreated, proxy state will persist across cluster and proxy version updates etc.
