Create your first Docker container with an ASP.NET web app

Publish to Azure App Service

Now that you have created a container image, you can publish it to Azure App Service Linux, also known as Web App for Containers. This allows you to run your container inside a fully-managed platform provided by Azure.

In the Solution Explorer, right-click the myFirstContainerApp project and select Publish.

Publish from Solution Explorer

On the Pick a publish target dialog box, click App Service Linux, choose Create New App Service for Containers, and click Publish.

This opens the Create App Service dialog, which helps you create all the necessary Azure resources to run the ASP.NET web app in Azure App Service Linux.

In the Create App Service dialog, click Sign In to sign in to your Azure account.

If you don’t already have an Azure account, click Create your free Azure account. This will open a web browser and allow you to sign up for a free trial of Azure. Once you’ve signed up, you can return to Visual Studio and click Sign In to continue creating your new App Service Linux instance.
