+                                "Recursive" means relabeling of all files on all Pod volumes by the container runtime.
+                                This may be slow for large volumes, but allows mixing privileged and unprivileged Pods sharing the same volume on the same node.
+
+                                "MountOption" mounts all eligible Pod volumes with `-o context` mount option.
+                                This requires all Pods that share the same volume to use the same SELinux label.
+                                It is not possible to share the same volume among privileged and unprivileged Pods.
+                                Eligible volumes are in-tree FibreChannel and iSCSI volumes, and all CSI volumes
+                                whose CSI driver announces SELinux support by setting spec.seLinuxMount: true in their
+                                CSIDriver instance. Other volumes are always re-labelled recursively.
+                                "MountOption" value is allowed only when SELinuxMount feature gate is enabled.
+
+                                If not specified and SELinuxMount feature gate is enabled, "MountOption" is used.

+# Operator architecture diagrams
+
+The Tailscale [Kubernetes operator][kb-operator] has a collection of use-cases
+that can be mixed and matched as required. The following diagrams illustrate
+how the operator implements each use-case.
+
+In each diagram, the "tailscale" namespace is entirely managed by the operator
+once the operator itself has been deployed.
+
+Tailscale devices are highlighted as black nodes. The salient devices for each
+use-case are marked as "src" or "dst" to denote which node is a source or a
+destination in the context of ACL rules that will apply to network traffic.
+
+Note, in some cases, the config and the state Secret may be the same Kubernetes
+Secret.
+
+## API server proxy
+
+[Documentation][kb-operator-proxy]
+
+The operator runs the API server proxy in-process. If the proxy is running in
+"noauth" mode, it forwards HTTP requests unmodified. If the proxy is running in
+"auth" mode, it deletes any existing auth headers and adds
+[impersonation headers][k8s-impersonation] to the request before forwarding to
+the API server. A request with impersonation headers will look something like:
+
+```
+GET /api/v1/namespaces/default/pods HTTP/1.1
+Host: k8s-api.example.com
+Authorization: Bearer <operator-service-account-token>
+Impersonate-Group: tailnet-readers
+Accept: application/json

+## L3 ingress
+
+[Documentation][kb-operator-l3-ingress]
+
+The user deploys an app to the default namespace, and creates a normal Service
+that selects the app's Pods. Either add the annotation
+`tailscale.com/expose: "true"` or specify `.spec.type` as `Loadbalancer` and
+`.spec.loadBalancerClass` as `tailscale`. The operator will create an ingress
+proxy that allows devices anywhere on the tailnet to access the Service.
+
+The proxy Pod uses `iptables` or `nftables` rules to DNAT traffic bound for the
+proxy's tailnet IP to the Service's internal Cluster IP instead.

+## L7 ingress
+
+[Documentation][kb-operator-l7-ingress]
+
+L7 ingress is relatively similar to L3 ingress. It is configured via an
+`Ingress` object instead of a `Service`, and uses `tailscale serve` to accept
+traffic instead of configuring `iptables` or `nftables` rules. Note that we use
+tailscaled's local API (`SetServeConfig`) to set serve config, not the
+`tailscale serve` command.

+## L3 egress
+
+[Documentation][kb-operator-l3-egress]
+
+1. The user deploys a Service with `type: ExternalName` and an annotation 
+  `tailscale.com/tailnet-fqdn: db.tails-scales.ts.net`.
+1. The operator creates a proxy Pod managed by a single replica StatefulSet, and a headless Service pointing at the proxy Pod.
+1. The operator updates the `ExternalName` Service's `spec.externalName` field to point
+  at the headless Service it created in the previous step.
+
+(Optional) If the user also adds the `tailscale.com/proxy-group: egress-proxies`
+annotation to their `ExternalName` Service, the operator will skip creating a
+proxy Pod and instead point the headless Service at the existing ProxyGroup's
+pods. In this case, ports are also required in the `ExternalName` Service spec.
+See below for a more representative diagram.

+## `ProxyGroup`
+
+[Documentation][kb-operator-l3-egress-proxygroup]
+
+The `ProxyGroup` custom resource manages a collection of proxy Pods that
+can be configured to egress traffic out of the cluster via ExternalName
+Services. A `ProxyGroup` is both a high availability (HA) version of L3
+egress, and a mechanism to serve multiple ExternalName Services on a single
+set of Tailscale devices (coalescing).
+
+In this diagram, the `ProxyGroup` is named `pg`. The Secrets associated with
+the `ProxyGroup` Pods are omitted for simplicity. They are similar to the L3
+egress case above, but there is a pair of config + state Secrets _per Pod_.
+
+Each ExternalName Service defines which ports should be mapped to their defined
+egress target. The operator maps from these ports to randomly chosen ephemeral
+ports via the ClusterIP Service and its EndpointSlice. The operator then
+generates the egress ConfigMap that tells the `ProxyGroup` Pods which incoming
+ports map to which egress targets.
+
+`ProxyGroups` currently only support egress.
