Как настроить docker?
Нужно копировать не только ShoppingCart.API, но и проекты, от которых он зависит
Я вот таким вот вариантом сделал. Была проблема с копированием, но я файл docker-compose перенес туда же где и Dockerfile

FROM mcr.microsoft.com/dotnet/sdk:5.0 AS build
WORKDIR /src

COPY ["ShoppingCart.API/ShoppingCart.API.csproj", "ShoppingCart.API/"]
COPY ["ShoppingCart.Domain.Entities/ShoppingCart.Domain.Entities.csproj", "ShoppingCart.Domain.Entities/"]
COPY ["ShoppingCart.Domain.Interfaces/ShoppingCart.Domain.Interfaces.csproj", "ShoppingCart.Domain.Interfaces/"]
COPY ["ShoppingCart.Infrastructure.Data/ShoppingCart.Infrastructure.Data.csproj", "ShoppingCart.Infrastructure.Data/"]
COPY ["ShoppingCart.Infrastructure.Business/ShoppingCart.Infrastructure.Business.csproj", "ShoppingCart.Infrastructure.Businesss/"]
COPY ["ShoppingCart.Services.Interfaces/ShoppingCart.Services.Interfaces.csproj", "ShoppingCart.Services.Interfaces/"]


RUN dotnet restore "ShoppingCart.API/ShoppingCart.API.csproj"
COPY . .
WORKDIR "/src/ShoppingCart.API"
RUN dotnet build "ShoppingCart.API.csproj" -c Release -o /app/build

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

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "ShoppingCart.API.dll"]
