Dockerizing aspnetcore-react 模板失败

Question

最近我从 react 模板创建了一个 aspnetcore-2.2 项目，正如我注意到的，它没有开箱即用的 docker 支持。

所以我添加了由 VS'17 生成的 dockerfile：

FROM microsoft/dotnet:2.2-aspnetcore-runtime AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM microsoft/dotnet:2.2-sdk AS build
COPY ["SpaProj.WebUI/SpaProj.WebUI.csproj", "SpaProj.WebUI/"]
COPY ["SpaProj.Application/SpaProj.Application.csproj", "SpaProj.Application/"]
COPY ["SpaProj.Domain/SpaProj.Domain.csproj", "SpaProj.Domain/"]
COPY ["SpaProj.Persistence/SpaProj.Persistence.csproj", "SpaProj.Persistence/"]
RUN dotnet restore "SpaProj.WebUI/SpaProj.WebUI.csproj"
COPY . .
WORKDIR "/src/SpaProj.WebUI"
RUN dotnet build "SpaProj.WebUI.csproj" -c Release -o
FROM build AS publish
RUN dotnet publish "SpaProj.WebUI.csproj" -c Release -o /app

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

就我的研究而言，最新的dotnet图像没有预先安装 nodejs，所以结果已成定局：

System.AggregateException: One or more errors occurred. (One or more errors occurred. (Failed to start 'npm'. To resolve this:.

[1] Ensure that 'npm' is installed and can be found in one of the PATH directories.
    Current PATH enviroment variable is: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
    Make sure the executable is in one of those directories, or update your PATH.

[2] See the InnerException for further details of the cause.)) ---> System.AggregateException: One or more errors occurred. (Failed to start 'npm'. To resolve this:. 

等等。

在那之后，我浏览了整整两天的网页来解决这个问题，经过一些研究，在我的 dockerfile 中添加了几行（我认为这将帮助我安装/启动 nodejs）：

FROM microsoft/dotnet:2.2-aspnetcore-runtime AS Base
WORKDIR /app
EXPOSE 80 443
FROM microsoft/dotnet:2.2-sdk AS build

# install node and npm
ENV NODE_VERSION 10.16.0
ENV NODE_DOWNLOAD_SHA 2e2cddf805112bd0b5769290bf2d1bc4bdd55ee44327e826fa94c459835a9d9a
ENV NODE_DOWNLOAD_URL https://nodejs.org/dist/v$NODE_VERSION/node-v$NODE_VERSION-linux-x64.tar.gz
RUN wget "$NODE_DOWNLOAD_URL" -O nodejs.tar.gz \
    && echo "$NODE_DOWNLOAD_SHA  nodejs.tar.gz" | sha256sum -c - \
    && tar -xzf "nodejs.tar.gz" -C /usr/local --strip-components=1 \
    && rm nodejs.tar.gz \
    && ln -s /usr/local/bin/node /usr/local/bin/nodejs
RUN curl -sL https://deb.nodesource.com/setup_10.x |  bash -
RUN apt-get install -y nodejs
# install npm packages first, this is slow so we want to minimise the number of un-cached runs
WORKDIR /src/SpaProj.WebUI/ClientApp/
COPY SpaProj.WebUI/ClientApp/package.json .
COPY SpaProj.WebUI/ClientApp/package-lock.json .
RUN npm install
RUN npm audit fix
# restore dotnet before build to allow it sit to cache
WORKDIR /
COPY ["SpaProj.Application/SpaProj.Application.csproj", "src/SpaProj.Application/"]
COPY ["SpaProj.Domain/SpaProj.Domain.csproj", "src/SpaProj.Domain/"]
COPY ["SpaProj.Persistence/SpaProj.Persistence.csproj", "src/SpaProj.Persistence/"]
COPY ["SpaProj.WebUI/SpaProj.WebUI.csproj", "src/SpaProj.WebUI/"]
RUN dotnet restore src/SpaProj.WebUI/SpaProj.WebUI.csproj
# copy source files and build
COPY . /src
RUN dotnet build /src/SpaProj.WebUI/SpaProj.WebUI.csproj --no-restore -c Release
RUN dotnet publish /src/SpaProj.WebUI/SpaProj.WebUI.csproj --no-restore -c Release -o /app
# Copy compiled app to runtime container
FROM base AS final
COPY --from=build /app .
CMD ["dotnet", "SpaProj.WebUI.dll"]

但它根本没有帮助。我还尝试了多阶段构建来从节点映像收集依赖项，如下所示：

FROM 10.16.1-jessie as node-build
WORKDIR /src
COPY SpaProj.WebUI/ClientApp .
RUN npm install
RUN npm run build

该应用程序仍然抛出相同的异常。

有没有人有同样的问题？有没有另一个是 dockerize 这种应用程序？
