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 dockerizing 的开发环境,我希望能够实时重新加载我的更改,而无需重新构建 docker 镜像.我正在使用 docker compose 因为 redis 是我的应用程序的依赖项之一,我喜欢能够链接 redis 容器
我在 docker-compose.yml
中定义了两个容器:
节点:构建:./节点链接:- Redis端口:- 8080"环境文件:- 节点-app.envRedis:图片:redis端口:- 6379"
我已经在我的 node
应用程序的 dockerfile 中添加了一个卷,但是如何在卷中安装主机的目录,以便我对代码的所有实时编辑都是反映在容器中?
这是我当前的 Dockerfile:
# 设置基础镜像为Ubuntu从节点:硼# 文件作者/维护者维护者 Amin Shah Gilani # 安装 nodemon运行 npm install -g nodemon# 添加一个/app 卷音量 [/app"]# TODO:链接当前的 .到/应用程序#定义工作目录工作目录/应用程序# 运行 npm install运行 npm 安装# 暴露端口曝光 8080# 使用 nodemon 运行应用程序CMD [nodemon",/app/app.js"]
我的项目如下所示:
<预><代码>/- docker-compose.yml- 节点-app.env- 节点/- 应用程序.js- Dockerfile.js查看他们的 文档
从它的外观来看,您可以在 docker-compose.yml 上执行以下操作
卷:- ./:/应用程序
其中 ./
是宿主目录,/app
是容器的目标目录.
以前的文档源现在会指向版本历史记录,您必须选择您正在使用的 compose 版本并查找参考.
附注:自本次编辑起,所有版本的语法都保持不变
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
I have two containers defined in my docker-compose.yml
:
node:
build: ./node
links:
- redis
ports:
- "8080"
env_file:
- node-app.env
redis:
image: redis
ports:
- "6379"
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?
Here's my current Dockerfile:
# Set the base image to Ubuntu
FROM node:boron
# File Author / Maintainer
MAINTAINER Amin Shah Gilani <amin@gilani.me>
# 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"]
My project looks like this:
/
- docker-compose.yml
- node-app.env
- node/
- app.js
- Dockerfile.js
Checkout their documentation
From the looks of it you could do the following on your docker-compose.yml
volumes:
- ./:/app
Where ./
is the host directory, and /app
is the target directory for the containers.
EDIT:
Previous documentation source now leads to version history, you'll have to select the version of compose you're using and look for the reference.
Side note: Syntax remains the same for all versions as of this edit
