Question

我正在使用angular2和docker并尝试构建图像。当我进入在“docker build -t angular-client：dev。”一切似乎都有效当我运行angular-client尝试创建一个容器时，它启动而不是停止。请有人帮我解决这个问题.....

**My 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"]


**My package.Json**

Answer 1

您的“npm start”命令失败。查看来自kitematic的输出，错误日志可能会导致您出现问题

Answer 2

缺少Angular CLI的dev依赖项。我不确定这是唯一的问题，但会导致您收到 ng serve 错误。

在docker中创建ng-cli容器不起作用
