将目录绑定到 docker 容器 [英] Bind a directory to a docker container

问题描述

我正在构建一个需要项目目录之外的模块的测试项目.项目文件夹在 docker 中，我想将该模块目录绑定到我项目的 docker 容器中.甚至有可能做到吗?还是我问错了问题?顺便说一句，我还是 docker 新手，所以我只是在尝试.

I'm building a test project that requires a module outside of the project directory. The project folder is in docker, and I would like to bind that module directory to the docker container of my project. Is it even possible to do it? Or am I asking the wrong question? By the way, I'm still new to docker so I'm just trying things out.

推荐答案

我的理解是，你需要将宿主文件夹挂载到容器中.所以试试这个:

My understand is, you need mount the host folder to the container. So try this:

docker run -v /host/project_folder:/container/project -t avian/project_image bash

解释

• -v - --volume=[] 绑定挂载卷
• /host/project_folder - 主机服务器的文件夹
• /container/project - 容器的文件夹

explanation

• -v - --volume=[] Bind mount a volume
• /host/project_folder - host server's folder
• /container/project - container's folder

最新的 docker 版本 (v1.9.1) 支持新命令 volume.所以你应该更容易在 docker 中管理卷.

The latest docker version (v1.9.1) support a new command volume. So you should be easier to manage volume in docker.

# For example, I need attach a volume to mysql container.
docker volume create --name mysql-data
docker run --name mysql -v mysql-data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=my-secret-pw -d mysql

这样，您可以随时删除容器 mysql，而不会丢失数据库数据.

With that, you can delete container mysql any time, without lost your database data.
