没有这样的文件或目录：Docker-compose up

Question

我使用docker-compose将我的平均应用程序停靠。这很好用。现在我尝试使用“卷”，以便我的角度应用程序（使用ng服务）和我的快速应用程序（带有nodemon.js）在编码时自动重启。但角度和快速容器都出现相同的错误：

angular_1   |

查看文件夹层次结构：

-project
  -client
    -Dockerfile
    -package.json
  -server
    -Dockerfile
    -package.json
  -docker-compose.yml

这是我的角度Dockerfile：

# Create image based on the official Node 10 image from dockerhub
FROM node:10

# 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"]

我的Dockerfile for express：

# Create image based on the official Node 6 image from the 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 3000

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

最后我的docker-compose.yml

version: '3' # specify docker-compose version

# Define the services/containers to be run
services:
  angular: # name of the first service
    build: client # specify the directory of the Dockerfile
    ports:
      - "4200:4200" # specify port forwarding
#WHEN ADDING VOLUMES, ERROR APPEARS!!!!!!
    volumes:
      - ./client:/usr/src/app

  express: #name of the second service
    build: server # specify the directory of the Dockerfile
    ports:
      - "3000:3000" #specify ports forwarding
    links:
      - database
#WHEN ADDING VOLUMES, ERROR APPEARS!!!!!!
    volumes:
      - ./server:/usr/src/app

  database: # name of the third service
    image: mongo # specify image to build container from
    ports:
      - "27017:27017" # specify port forwarding

Answer 1

你的卷部分应该是这样的：

    volumes:
      - .:/usr/app
      - /usr/app/node_modules

在Docker容器中安装源文件夹node_modules后，'覆盖'，所以你需要添加'/ usr / app / node_modules'。完整的教程与适当的docker-compose.yml - https://all4developer.blogspot.com/2019/01/docker-and-nodemodules.html
