Question

我对docker很新，我正在尝试使用Angular CLI应用程序。我设法通过我的docker容器在本地运行它。它工作得很好，但是当我尝试从我的服务器运行它时它会失败。

服务器托管在DigitalOcean上：

512 MB Memory / 20 GB Disk / FRA1 - Ubuntu Docker 17.03.0-ce on 14.04

我使用dockerhub将我的容器转移到服务器。

记录容器时，它给了我：

** NG Live Development Server is running on http://0.0.0.0:4200. **

这是我的Dockerfile：

# Create image based on the official Node 6 image from dockerhub
FROM node:6

# Create a directory where our app will be placed
RUN mkdir -p /usr/src/app

# Change directory so that our commands run inside this new directory
WORKDIR /usr/src/app

# Copy dependency definitions
COPY package.json /usr/src/app

# Install dependecies
RUN npm install

# Get all the code needed to run the app
COPY . /usr/src/app

# Expose the port the app runs in
EXPOSE 4200

# Serve the app
CMD ["npm", "start"]

为什么它在本地运行并在服务器上失败？我错过了一些依赖项吗？

ng serve是一个angular-cli命令。如果您想在数字海洋上启动服务器，我猜你需要在docker文件中全局安装它：

RUN npm i -g angular-cli

我认为在生产中使用裸节点服务器简单地运行应用程序会更为典型。所以你的CMD看起来更像是这样：

CMD ["node", "app.js"]

Docker Container在本地工作但在服务器上失败
