The former is the source-to-image builder, and the latter is a runtime-only image.

The .NET Core 3.0 Release Notes for Containers is an extension of the .NET Core 3.0 Release Notes for RPMs. See .NET Core 3.0 Release Notes for RPMs for information on known issues, the operating system architecture, privacy, and support.

2.1. New Variables

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 do when the application is loading. Defaults to false.

See Environment Variables for the list of environment variables available with .NET Core 3.0.
