Due to its small footprint (OS image size), Alpine is suited for embedded scenarios on ARM32.

Things leading to this:

• Today dotnet core is supported on ARM32.
• Today dotnet core 2.1 is running on Alpine for x86.
• Today dotnet core 3.1 is running on Alpine for ARM64.

It is expected to have symmetry in OS support between different CPU architectures where possible.

(If/when this is implemented the docker images for running .net core application should be available. )
