# Scale a Deployment Using Replicas

## Scale a Deployment Using Replicas

You can update a deployment to change the number of replicas as shown below.

### Example Customization

Adding more Pod provisioning helps with resiliency. The following example file sets the number of replicas for **`ess-pod-provision`** deployment to **`2`** .

1. Go to your ESS installation directory:

   ```sh
   cd ${HOME}/ess
   ```
2. Modify the **`kustomization.yaml`** (i.e., step 3 of the [Applying Your Customizations](https://docs.inrupt.com/ess/2.5/installation/customize-configurations) procedure).\
   Specifically, add the highlighted content to the **`kustomization.yaml`** file under the **`replicas`** key:\\

   {% hint style="info" %} **Tip**

   If **`replicas`** key does not exist in **`kustomization.yaml`** , add the key **`replicas`** as well. {% endhint %}

   <pre class="language-yaml"><code class="lang-yaml"># kustomization.yaml in your ESS installation directory

   # ...  Preceding content omitted for brevity 
   # ...

   replicas:
   <strong>- name: ess-pod-provision
   </strong><strong>  count: 2
   </strong></code></pre>

   3\. Continue with the rest of the \[Applying Your Customizations]\(../../customize-configurations/) procedure.
