**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"]

缺少Angular CLI的dev依赖关系。我不确定这是否是唯一的问题，但它会导致您收到的错误ng。

你的“npm start”命令失败。检出输出来自kitematic，那里的错误日志可能会导致您遇到问题
