Can you confirm if this occurs on other versions of SqlClient?

Can you also try explicitly setting the runtime id as discussed in this thread: dotnet/SqlClient#2030 (comment)

[xs2bharat]

Issue is fixed when switched to docker image mcr.microsoft.com/dotnet/aspnet:6.0.28-alpine3.18

[kf-gonzalez2]

It might be an issue in the .Net platform detection logic not detecting alpine 3.19 as linux.

Maybe dotnet/dotnet-docker#5243 is related?
