https://github.com/aspnet/JavaScriptServices/issues/1534#issuecomment-366605094
modified the angular app docker file
change this line
FROM microsoft/aspnetcore:2.0 AS base
to
FROM microsoft/aspnetcore-build:2.0 AS base
Updated Docker file
FROM microsoft/aspnetcore-build:2.0 AS base
WORKDIR /app
EXPOSE 80
FROM microsoft/aspnetcore-build:2.0 AS build
WORKDIR /src
COPY MeroRental.sln ./
COPY WebApp/WebApp.csproj WebApp/
RUN dotnet restore -nowarn:msb3202,nu1503
COPY . .
WORKDIR /src/WebApp
RUN dotnet build -c Release -o /app
FROM build AS publish
RUN dotnet publish -c Release -o /app
FROM base AS final
WORKDIR /app
COPY --from=publish /app .
ENTRYPOINT ["dotnet", "WebApp.dll"]
