【问题描述】：

我正在尝试使用 Visual Studio 2017 中的 .net core angular spa 模板创建图像。我不断收到 npm 错误 127。即使我可以看到 npm run build 命令正在执行并且它通过了这一步。我尝试在构建开始时在映像上安装节点。那里也没有成功。这就是我的 dockerfile 的样子。

FROM microsoft/dotnet:2.1-aspnetcore-runtime AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM microsoft/dotnet:2.1-sdk AS build
WORKDIR /src
COPY ["AngularNetCoreDockerApp/AngularNetCoreDockerApp.csproj", "AngularNetCoreDockerApp/"]
RUN dotnet restore "AngularNetCoreDockerApp/AngularNetCoreDockerApp.csproj"
COPY . .
WORKDIR "/src/AngularNetCoreDockerApp"
RUN dotnet build "AngularNetCoreDockerApp.csproj" -c Release -o /app

FROM build AS publish
RUN dotnet publish "AngularNetCoreDockerApp.csproj" -c Release -o /app

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

【解决方案1】：

它最终与 dockerfile 有关。我最终使用了这个

FROM microsoft/dotnet:2.1.301-sdk AS builder
WORKDIR /source

RUN curl -sL https://deb.nodesource.com/setup_10.x |  bash -
RUN apt-get install -y nodejs

COPY *.csproj .
RUN dotnet restore

COPY ./ ./

RUN dotnet publish "./angular-app.csproj" --output "./dist" --configuration Release --no-restore

FROM microsoft/dotnet:2.1.1-aspnetcore-runtime
WORKDIR /app
COPY --from=builder /source/dist .
EXPOSE 80
ENTRYPOINT ["dotnet", "angular-app.dll"]

【解决方案2】：

我最终将构建拆分为多个阶段。

首先，我从 *.csproj 文件中删除了目标 PublishRunWebpack，以确保该应用在发布期间不会构建 spa。

之后我的 Dockerfile 看起来像这样：

FROM mcr.microsoft.com/dotnet/core/aspnet:3.0-buster-slim AS base
WORKDIR /app
EXPOSE 80

FROM node:latest AS node-packages
WORKDIR /web
COPY "ProjectFolder/ClientApp/package.json" .
COPY "ProjectFolder/ClientApp/package-lock.json" .
RUN npm install

FROM mcr.microsoft.com/dotnet/core/sdk:3.0-buster AS dotnet-packages

WORKDIR /src
COPY ["ProjectFolder/ProjectFile.csproj", "ProjectFolder/"]
RUN dotnet restore "ProjectFolder/ProjectFile.csproj"

FROM node-packages AS node-build
WORKDIR /web
COPY ProjectFolder/ClientApp .
RUN npm run build --prod

FROM dotnet-packages AS dotnet-build
WORKDIR /src
COPY . .
WORKDIR "/src/ProjectFolder"
RUN dotnet build "ProjectFile.csproj" -c Release -o /app/build
RUN dotnet publish "ProjectFile.csproj" -c Release -o /app/publish

FROM node-build AS node-publish
FROM dotnet-build AS dotnet-publish

FROM base AS final
WORKDIR /app
COPY --from=dotnet-publish /app/publish .
WORKDIR /app/ClientApp/dist
COPY --from=node-publish /web/dist .

WORKDIR /app
ENTRYPOINT ["dotnet", "ProjectFile.dll"]
