+# Manage a single shared session for the Online Boutique apps
+
+By default, when you deploy this sample app, the Online Boutique's `frontend` generates a `shop_session-id` cookie per browser session.
+But you may want to share one unique `shop_session-id` cookie across all browser sessions.
+This is useful for multi-cluster environments.
+
+## Deploy Online Boutique to generate a single shared session
+
+To automate the deployment of Online Boutique to manage a single shared session you can leverage the following variation with [Kustomize](../..).
+
+From the `kustomize/` folder at the root level of this repository, execute this command:
+
+```bash
+kustomize edit add component components/single-shared-session
+```
+
+This will update the `kustomize/kustomization.yaml` file which could be similar to:
+
+```yaml
+apiVersion: kustomize.config.k8s.io/v1beta1
+kind: Kustomization
+resources:
+- base
+components:
+- components/single-shared-session
+```
+
+You can locally render these manifests by running `kubectl kustomize .` as well as deploying them by running `kubectl apply -k .`.
