修改了角度应用docker文件

更改此行

  FROM microsoft / aspnetcore：2.0 AS base 
  

到

  FROM microsoft / aspnetcore-build：2.0 AS base 
  

更新的Docker文件

 从Microsoft / aspnetcore-build：2.0 AS基础
 WORKDIR / app 
暴露80 
 
从microsoft / aspnetcore-build：2.0 AS构建
 WORKDIR / src 
 COPY MeroRental.sln ./ 
 COPY WebApp / WebApp.csproj WebApp / 
运行dotnet restore -nowarn：msb3202，nu1503 
 COPY。 。 
 WORKDIR / src / WebApp 
 RUN dotnet build -c Release -o / app 
 
 FROM build AS发布
 RUN dotnet publish -c Release -o / app 
 
从基础AS最终
 WORKDIR / app 
 COPY --from = publish / app。 
 ENTRYPOINT [ dotnet， WebApp.dll] 
  

I, have create a angular app in mac os using vs2017 and followed the sample form Creating a new Angular project on Mac with Visual Studio with docker support for three project. Since the other project are Web API. Since the other project are successfully running on the docker. However only the angular app is not running and it throw an error as below

Tried to solve the error from this link https://github.com/aspnet/JavaScriptServices/issues/707 but no result.

解决方案

Found the solution from this link and it worked.

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"]
