 A **Dockerfile** is a file that defines a set of instructions that creates an image. Each instruction in the **Dockerfile** creates a layer in the image. For the most part, when you rebuild the image, only the layers that have changed are rebuilt. The **Dockerfile** can be distributed to others and allows them to recreate a new image in the same manner you created it. While this allows you to distribute the *instructions* on how to create the image, the main way to distribute your image is to publish it to a registry.

-Official .NET Core Docker images are published to the Microsoft Container Registry (MCR) and are discoverable at the [Microsoft .NET Core Docker Hub repository](https://hub.docker.com/_/microsoft-dotnet/).

 Microsoft provides images that are tailored for specific scenarios. For example, the [ASP.NET Core repository](https://hub.docker.com/_/microsoft-dotnet-aspnet/) provides images that are built for running ASP.NET Core apps in production.

+If the .NET app uses the *System.Drawing.Common* assembly, libgdiplus will also need to be installed. Because [*System.Drawing.Common* is no longer supported on Linux](../../compatibility/core-libraries/6.0/system-drawing-common-windows-only.md), this only works on .NET 6 and requires setting the `System.Drawing.EnableUnixSupport` runtime configuration switch.
