如何使用docker-compose和“〜/path/on/host"挂载主机目录在运行主机时指定，而不是在docker-compose文件中指定 [英] How to mount a host directory with docker-compose, with the "~/path/on/host" to be specified when running the host, not in the docker-compose file

问题描述

我想知道如何使用docker-compose挂载主机目录.

I'm wondering how you can mount a host directory using docker-compose.

此刻，我仅使用常规的Dockerfile，并且工作正常.运行容器时，只需在主机上指定路径，再在容器上指定路径.

At the moment I'm just using a regular Dockerfile and it's working fine. When I run the container I just specify the path on my host and the path on the container.

docker run -d -p 3000:3000 -v ~/path/on/host:/path/on/container my-container

我想使用docker-compose来实现这一点，但是我不确定它是如何工作的.我的docker compose在下面.

I'd like to to achieve this using docker-compose but I'm not sure how this works.My docker compose is below.

version: '3'

services:
  my-app:
    build:
      context: .
      dockerfile: ./path/to/Dockerfile

此外，我需要在运行主机时指定〜/path/on/host，而不是在docker-compose文件中.

In addition, I need the ~/path/on/host to be specified when running the host, not in the docker-compose file.

推荐答案

version: '3'

services:
  my-app:
    build:
      context: .
      dockerfile: ./path/to/Dockerfile
    volumes:
      - ~/path/on/host:/path/on/container
    ports:
      - "3000:3000"

然后，您可以使用 docker-compose up -d 启动服务.确保首先停止并删除使用docker命令启动的容器，否则会发生冲突.

Then you can start your service with docker-compose up -d. Make sure to stop and remove first the container you started using docker commands otherwise you will get conflicts.

基于评论的

创建一个包含以下内容的.env文件:

Create a .env file with the contents:

HOST_PATH=~/path/on/host

并更改您的docker-compose.yml:

and change your docker-compose.yml:

version: '3'

services:
  my-app:
    build:
      context: .
      dockerfile: ./path/to/Dockerfile
    volumes:
      - ${HOST_PATH}:/path/on/container
    ports:
      - "3000:3000"
