angular - 为 Angular 项目启用 Docker 支持

Question

Visual Studio 2017 中是否有办法自动启用对 asp.net-core Angular 项目的 Docker 支持？创建新选项时该选项被禁用。它仅适用于Web 应用程序 (MVC)。

在创建项目后，我能够为 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，我收到一个异常，即 node.js 不可用。

System.AggregateException occurred HResult=0x80131500 Message=One or more errors occurred. (Failed to start Node process. To resolve this:.

[1] Ensure that Node.js 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 Node executable is in one of those directories, or update your PATH.

如果无法自动创建它，如何手动为我的 Angular 项目启用 Docker 支持？

Answer 1

我解决了我的问题。

我还需要在我的镜像上安装nodejs，因为webpack需要它。我已更改 Dockerfile 以安装 Nodejs 版本 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，并且它安装在文件夹nodejs中，因此 WebpackDevMiddleware 找不到节点可执行文件。
