Windows Server, version 1803 no longer supported by .NET Core
Windows Server, version 1803 is no longer supported. As a result, this version of Windows is no longer supported by the .NET Team and we will no longer produce .NET Core container images for this Windows version.
Docker tags that contain nanoserver-1803 are no longer being produced. We will not delete existing images or those tags. However, they contain unsupported builds of Nano Server and .NET Core.
Pulling manifest tags
These changes also affect manifest tags (AKA “multi-arch tags“), such as 3.0, 3.0.0. These are tags that are supported on multiple operating systems, and do not contain the operating system in them. As a result of no longer producing new images for Windows Server, version 1803, manifest tags no longer include entries for Windows 10, version 1803, and Windows Server, version 1803. That means that .NET Core manifest tags are no longer usable on those Windows versions.
If you pull a manifest tag on one of the Windows versions described, you may get one of the following error messages:
a Windows version 10.0.18362-based image is incompatible with a 10.0.17134 host
no matching manifest for windows/amd64 in the manifest list entries
no matching manifest for unknown in the manifest list entries
If you need to still use Nano Server, version 1803 images (even though it is no longer supported), you will need to use tags that include the Nano Server version (these are non-manifest tags), for example mcr.microsoft.com/dotnet/core/runtime:3.0-nanoserver-1803.
