How Do I Enable Deployment Slots?

If you are looking to deploy your web application on Azure, then there is a good chance that you have heard about deployment slots. Deployment slots are a feature offered by the Azure App Service that enable you to deploy and test your web application in a separate environment before deploying it to production. In this tutorial, we will walk through the process of enabling deployment slots for your web application.

Step 1: Create an Azure Web App

Before we can enable deployment slots, we need to create an Azure Web App. You can create a new web app by following these steps:

1. Log in to the Azure portal.
2. Click on the + Create a resource button.
3. Select Web App from the list of available resources.
4. Enter a unique name for your web app and select the appropriate subscription, resource group, and operating system.
5. Click on Review + create and then click on Create to create your new web app.

Step 2: Enable Deployment Slots

Once you have created your web app, follow these steps to enable deployment slots:

1. Navigate to your web app in the Azure portal.
2. Click on Deployment slots under Deployment in the left-hand menu.
3. Click on Add Slot at the top of the screen.
4. Enter a name for your new deployment slot and select whether you want to copy settings from an existing slot or start with an empty configuration.
• If you choose to copy settings from an existing slot, select the slot from which you want to copy settings from and then click OK.

Note: If you choose to start with an empty configuration, you will need to configure your new slot manually.

5. Click on Add to create your new deployment slot.

Step 3: Deploy Your Web App

Now that we have enabled deployment slots, we can deploy our web app to the appropriate slot. Follow these steps:

1. Navigate to your web app in the Azure portal.
2. Click on Deployment Center under Deployment in the left-hand menu.
3. Select the appropriate deployment source. You can choose from GitHub, Azure DevOps, Bitbucket, and more.
4. Follow the instructions to connect your selected deployment source to your web app.
5. Select the appropriate branch or repository and click on Save.

Step 4: Swap Slots

Once you have deployed your web app to a deployment slot, you can test it before swapping it with production.

Note: When you swap slots, all of the configuration settings and content will be swapped between production and staging slots.

Conclusion:

In conclusion, enabling deployment slots for your Azure Web App is a great way to test changes before deploying them to production. By following these simple steps, you can easily enable, deploy, and swap slots for your web app. Good luck with your deployment!
