为 Angular 项目启用 Docker 支持 [英] Enable Docker support for Angular project
问题描述
Visual Studio 2017 中是否有办法自动启用 Docker 对 asp.net-core Angular 项目的支持?创建新选项时禁用该选项.它仅适用于 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).
我可以在创建项目后为 Angular 项目启用 Docker 支持(项目->添加->Docker 支持)，但是当我启动应用程序时，我得到一个异常，即 node.js 不可用.
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，如何手动为我的 Angular 项目启用 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.
我还需要在我的图像上安装 nodejs，因为 webpack 需要它.我已更改我的 Dockerfile 以安装 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 还不够，因为这会安装 nodejs 的第 4 版，并且它安装在文件夹 nodejs 中，因此 WebpackDevMiddleware 没有找到节点可执行文件.
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.
