I fix this problem by change Dockerfile
FROM microsoft/dotnet:2.2.0-aspnetcore-runtime AS base instead of FROM microsoft/dotnet:2.2-aspnetcore-runtime AS base

@1015450578 - are you sure you have the most recent image pulled locally? The microsoft/dotnet:2.2-aspnetcore-runtime tag is a floating tag. Prior to 2.2 being released this tag pointed to the various preview releases. It appears to me that you pulled this tag during preview and didn't re-pull once RTM was released.

Related to https://github.com/dotnet/announcements/issues/93#issuecomment-447200268. FWIW this is the correct repo to log all issues related to the microsoft/dotnet Docker images.

the docker image that I pulled:

[MichaelSimons]

.NET Core 2.2.0 was released on Dec 4 - https://blogs.msdn.microsoft.com/dotnet/2018/12/04/announcing-net-core-2-2/. Your image is a preview version. Please re-pull the image via - docker pull microsoft/dotnet 2.2-aspnetcore-runtime to get the latest image.

[MichaelSimons]

Closing as there was a preview version of the 2.2 image cached locally. Images need to be explicitly re-pulled when new ones are available.
