FROM mcr.microsoft.com/dotnet/sdk:8.0 AS build
WORKDIR /src
COPY ["ScanApi/ScanApi.csproj", "ScanApi/"]
RUN dotnet restore "ScanApi/ScanApi.csproj"
COPY . .
RUN dotnet publish "ScanApi/ScanApi.csproj" -c Release -o /app/publish
FROM mcr.microsoft.com/dotnet/aspnet:8.0 AS runtime
WORKDIR /app
COPY --from=build /app/publish .
EXPOSE 8080

# docker-compose.yml
services:
api:
build: .
ports: ["8080:8080"]
environment:
- ConnectionStrings__DefaultConnection=${DB_CONNECTION}
