我使用docker-compose将我的mean应用程序容器化了。这很好用。
现在我尝试使用"volumes",使我的angular应用程序(使用ng serve)和我的express应用程序(使用nodemon.js)在编码时自动重启。
但是,无论是angular还是express容器都出现了相同的错误:
angular_1 |

看一下我的文件夹层次结构:
-project
-client
-Dockerfile
-package.json
-server
-Dockerfile
-package.json
-docker-compose.yml
这是我的 Angular 的 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 Express Dockerfile:
# 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"]
最后是我的docker-compose.yml文件
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
./server
和./client
