+# The extra TiDB cluster Components
+
+> **Note:**
+>
+> This setup is for test or demo purpose only and **IS NOT** applicable for critical environment. Refer to the [Documents](https://pingcap.com/docs/stable/tidb-in-kubernetes/deploy/prerequisites/) for production setup.
+
+
+The following steps will create a TiDB cluster with monitoring and auto-scaler, the monitoring data is not persisted by default.
+
+**Prerequisites**: 
+- Has TiDB operator `v1.1.0-beta.2` or higher version installed. [Doc](https://pingcap.com/docs/stable/tidb-in-kubernetes/deploy/tidb-operator/)
+ 
+   
+## Auto-scaling
+
+> **Note:**
+>
+> The Auto-scaling feature is still in alpha, you should enable this feature in TiDB Operator by setting values.yaml:
+ ```yaml
+features:
+  AutoScaling=true
+```
+
+Auto-scale the cluster based on CPU load
+```bash
+> kubectl -n <namespace> apply -f ./
+```
+
+## Destroy
+
+```bash
+> kubectl -n <namespace> delete -f ./
+```
