WORKDIR /app

FROM mcr.microsoft.com/dotnet/core/sdk:6.0-alpine AS build
WORKDIR /src

RUN dotnet build "RentServiceApp.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "RentServiceApp.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .

Hi guys! maybe my solution will help someone. I still did not understand what the reason was, but by experiment, I got a working configuration. My problem was that the assembly of two images (via compose) worked correctly for me only when I launched the solution through Visual Studio. When I tried to build via "docker-compose -f docker-compose.yml up -d", the reverse proxy did not work correctly. Below I give examples of my working configs: P.S. You also need to take into account that the basic images (which are referenced in the example) have changed a long time ago: for build: microsoft.com/dotnet/core/sdk:3.1-buster AS build
