asp.net - Docker中带有JavaScriptServices的ASP.NET Core项目无法启动节点

Question

我在使站点在Docker容器中正常运行时遇到问题。该容器可以很好地构建并运行，但是在导航到页面时，它无法加载JavaScript服务。

这是Dockerfile

FROM microsoft/aspnetcore-build:2.0 AS builder
WORKDIR /app

ADD company_cas.pem /usr/local/share/ca-certificates/company_cas.crt
RUN update-ca-certificates

COPY company_cas.pem ./
RUN npm config set cafile company_cas.pem

# Run NPM install for dependencies
COPY package.json ./
RUN npm install

# Copy csproj and restore as distinct layers
COPY *.csproj ./
RUN dotnet restore

# Copy everything else and build
COPY . ./

RUN dotnet publish -c Release -o out

# Build runtime image
FROM microsoft/aspnetcore:2.0
WORKDIR /app
COPY --from=builder /app/out .
ENTRYPOINT ["dotnet", "web.dll"]

我正在使用 microsoft/aspnetcore-build:2.0基本镜像，并且npm确实在运行，因此，据我所知，Node已安装。

失败请求的输出是-

这是为ASP.NET设置新路径来查找Node的问题吗？如果是这样，对在Docker中应该使用的路径有什么想法吗？

我想我忽略了运行时镜像基础容器。

更改为FROM microsoft/aspnetcore-build:2.0，现在很好。
