Release Notes for .NET Core 3.1 containers
Abstract
Making open source more inclusive
Red Hat is committed to replacing problematic language in our code, documentation, and web properties. We are beginning with these four terms: master, slave, blacklist, and whitelist. Because of the enormity of this endeavor, these changes will be implemented gradually over several upcoming releases. For more details, see our CTO Chris Wright’s message.

Chapter 2. New environment variables
The following environment variables have been added for the .NET Core 3.1 container image.
DOTNET_RESTORE_CONFIGFILE Specifies a NuGet.Config file to be used for restore operations. This variable cannot be combined with DOTNET_RESTORE_SOURCES.
DOTNET_PUBLISH_READYTORUN When set to true, the application will be compiled ahead-of-time. This reduces startup time by reducing the amount of work the JIT compiler needs to perform when the application is loading. Defaults to false.
See Environment Variables for the list of environment variables available with .NET Core 3.1.
