如何使用compose将docker volume装入我的docker项目？ [英] How to mount docker volume into my docker project using compose?

问题描述

我有一个Maven项目。我在Docker内部运行我的Maven构建。但是问题在于它每次运行时都会下载所有的Maven依赖项，并且它不会缓存任何这些Maven下载。

我发现了一些工作，您将本地.m2文件夹安装到Docker容器中。但这将使构建依赖于本地设置。我想做的是创建一个卷（长实时），并将该卷链接/挂载到Docker内的 .m2 文件夹。这样当我第二次运行Docker版本时，它不会下载所有内容。它不会依赖于环境。

如何使用docker-compose？

解决方案

不知道你的确切配置，我会使用这样的东西...

  2
 
服务：
 maven：
图片：无论
卷：
  -  m2-repo：/home/foo/.m2/repository 
 
卷：
 m2-repo：
  

名为 m2-repo 的数据卷映射到 /home/foo/.m2/repository （调整路径有必要的）。数据量可以在Docker Compose项目的上/下/开始/停止状态下生存。

您可以通过运行类似 docker-撰写-v ，这将破坏容器和卷。

I have a Maven project. I'm running my Maven builds inside Docker. But the problem with that is it downloads all of the Maven dependencies every time I run it and it does not cache any of those Maven downloads.

I found some work arounds for that, where you mount your local .m2 folder into Docker container. But this will make the builds depend on local setup. What I would like to do is to create a volume (long live) and link/mount that volume to .m2 folder inside Docker. That way when I run the Docker build for the 2nd time, it will not download everything. And it will not be dependent on environment.

How can I do this with docker-compose?

解决方案

Without knowing your exact configuration, I would use something like this...

version: "2"

services:
  maven:
    image: whatever
    volumes:
      - m2-repo:/home/foo/.m2/repository

volumes:
  m2-repo:

This will create a data volume called m2-repo that is mapped to the /home/foo/.m2/repository (adjust path as necessary). The data volume will survive up/down/start/stop of the Docker Compose project.

You can delete the volume by running something like docker-compose down -v, which will destroy containers and volumes.
