如何在Docker Compose中将主机目录挂载为卷 [英] How do I mount a host directory as a volume in docker compose

问题描述

我有一个正在进行dockerizing的开发环境，并且我希望能够实时重新加载所做的更改而不必重建docker映像。我正在使用docker compose，因为redis是我应用程序的依赖项之一，而且我希望能够链接redis容器

I have a development environment I'm dockerizing and I would like the ability to livereload my changes without having to rebuild docker images. I'm using docker compose because redis is one of my app's dependencies and I like being able to link a redis container

我在<$ c $中定义了两个容器c> docker-compose.yml ：

node:
    build: ./node
    links:
        - redis
    ports:
        - "8080"
    env_file:
        - node-app.env

redis:
    image: redis
    ports:
        - "6379"

我已经到达我的 node 应用程序的dockerfile中的位置，我在其中添加了一个卷，但是如何将主机的目录挂载到该卷中，以便所有活动对代码的编辑是否反映在容器中？

I've gotten to the point in my node app's dockerfile where I add a volume, but how do I mount the the host's directory in the volume so that all my live edits to the code are reflected in the container?

这是我当前的Dockerfile：

Here's my current Dockerfile:

# Set the base image to Ubuntu
FROM    node:boron

# File Author / Maintainer
MAINTAINER Amin Shah Gilani <[e-mail]>

# Install nodemon
RUN npm install -g nodemon

# Add a /app volume
VOLUME ["/app"]

# TODO: link the current . to /app

# Define working directory
WORKDIR /app

# Run npm install
RUN npm install

# Expose port
EXPOSE  8080

# Run app using nodemon
CMD ["nodemon", "/app/app.js"]

我的项目如下：

/
- docker-compose.yml
- node-app.env
- node/
  - app.js
  - Dockerfile.js

从外观上，您可以在docker-compose上执行以下操作。 yml

From the looks of it you could do the following on your docker-compose.yml

volumes:
    - ./:/app
