# Post Deploy Configurations

### Update CORS in Stratus

To allow your application to Upload or Delete files in **Stratus**, you must whitelist your app domain in Stratus **Bucket CORS** settings. Without this configuration, Stratus will reject requests from unknown origins. To complete this setup, follow the below steps:

1. In the Stratus component. Go to the **Configuration** tab → **Bucket CORS** → **Add Domain**. ![permissions_done](https://catalyst-docs-development.zohostratus.in/images/tutorials/workdrivesync/bucket-cors-setup-stratus.webp) 

2. From the pop-up that appears, select **PUT, GET** and **DELETE** as allowed request methods and paste your app domain obtained from the previous step in the Domain URL.

3. Click **Add** to save the domain settings.

> Note: If you are running the app locally using Catalyst Serve, add your localhost URL with the active port to the Bucket CORS list to enable Stratus access.

## Create Rule

Now that the Publisher and the Event Function are configured, let us define how the events should be processed and delivered by setting up a Rule.

Follow these steps to create the Rule:

1. In the Developer Console, select your project: *WorkDriveSync*.

2. Go to **Catalyst Signals** and click on **Rules** in the left navigation.

3. Click **Add Rule**, then provide a name and description for your rule.

### Define Event Source

4. Under Source, click **Choose Event**, switch to **Catalyst Publishers** tab, and select the Cloud Scale Stratus Publisher you added earlier. Select the **Object Upload** event and click on **Next**. ![Choose event and select catalyst publisher](https://catalyst-docs-development.zohostratus.in/images/tutorials/workdrivesync/catalyst-publisher-stratus-event-object-upload.webp) 

5. Choose your target bucket in the **Additional Settings** and click **Done**.

6. Click **Choose Target** and name your target.

7. Under Consumer Type, select the Event Function we created earlier using the CLI.

8. Set the **Dispatch Policy** to **Instant** and check on **Send as Single Event**. 
![Select dispatch policy](https://catalyst-docs-development.zohostratus.in/images/tutorials/workdrivesync/single-select-event-workdrive.webp) 

9. Save the target configurations, then click **Save** again to finalize the rule.

10. Repeat the above steps for the **Object Delete** event with the same configurations.

Once you have created the Rule for **Object Delete**, the Rule setup is complete. You can now proceed to test the application.
