为Angular项目启用Docker支持 [英] Enable Docker support for Angular project

问题描述

Visual Studio 2017中是否有一种方法可以自动为asp.net核心 Angular 项目启用Docker支持?创建新选项时，该选项被禁用.它仅可用于 Web应用程序(MVC).

Is there a way in Visual Studio 2017 to automatically enable Docker support for an asp.net-core Angular project? The option is disabled when creating a new one. It is only available for Web Application (MVC).

创建项目后，我能够为有角项目启用Docker支持(Project-> Add-> Docker Support)，但是当我启动应用程序时，出现一个异常，提示node.js不可用./p>

I am able to Enable Docker support (Project->Add->Docker Support) for the angular project after I have created the project, but when I start the application I get an exception that node.js is not available.

如果无法自动创建它，如何为我的Angular项目手动启用Docker支持?

If it is not possible to create it automatically how can I manually get the Docker support enabled for my Angular project?

推荐答案

我解决了我的问题.

我还需要在映像上安装nodejs，因为webpack需要它.我已将Dockerfile更改为也安装nodejs版本6

I needed to install nodejs also on my image, cause it is needed by webpack. I have changed my Dockerfile to also install nodejs version 6

FROM microsoft/aspnetcore:2.0
RUN apt-get update && \
    apt-get install -y wget && \
    apt-get install -y gnupg2 && \
    wget -qO- https://deb.nodesource.com/setup_6.x | bash - && \
    apt-get install -y build-essential nodejs
# Rest of Dockerfile

仅使用RUN apt-get update && apt-get install -y nodejs是不够的，因为这会安装nodejs的版本4，并将其安装在文件夹nodejs中，因此WebpackDevMiddleware找不到节点可执行文件.

Using only RUN apt-get update && apt-get install -y nodejs was not enough, cause this installs version 4 of nodejs and it was installed in folder nodejs, so that the WebpackDevMiddleware did not find the node executable.
