如何使用docker-compose将docker容器目录映射到主机？

问题描述

给出以下docker-compose.yml设置：

Given following docker-compose.yml setup:

version: '3.7'

services:
  reverse:
    container_name: nginx-reverse-proxy
    hostname: nginx-reverse-proxy
    image: nginx:stable
    ports:
      - 80:80
      - 433:433
    volumes:
      - type: bind
        source: ./config
        target: /etc/nginx
        consistency: consistent

结果 ./ config 文件夹映射到容器 nginx-reverse-proxy ，因此在容器上的空 / etc / nginx 目录中。

Results in ./config the folder beeing mapped to the container nginx-reverse-proxy and therefore in an empty /etc/nginx directory on the container.

如我的问题所述，目标是查看内容（从图像中创建）的容器，并使该内容对主机可见在 ./ config 。

As stated in my question the goal is to see the content, the container (from the image) creates, and make it visible to the host at ./config.

我当前的搜索不断导致如何将Directoy从主机映射到容器（

My current search constantly results in how to map directoy from host to container (which i do not want).

任何提示/解决方案赞赏。

Any hints/solutions are appreciated. Thanks!

我当前的解决方案很丑：
我用docker创建了容器，并从 / etc / nginx复制了文件到 ./ config 。删除容器并使用 docker-compose up 可以正常工作，并且 nginx 开始，因为所需的文件已在主机上。

My current solution is ugly:I created the container with docker and copied the files from /etc/nginx to ./config. Removing the container and using the docker-compose up works and nginx starts because the needed files are already on the host.

编辑：该文件夹在创建时不存在。 Docker compese正在按照文档中的说明创建文件夹。

The folder is not present at creation. Docker compese is creating the folder as stated in the docs.

推荐答案

从以下位置读取：

新卷可以通过容器预先填充其内容。

New volumes can have their content pre-populated by a container.

因此，一个简单的docker-compose（在名为nginx的文件夹中）：

---

So a simple docker-compose (inside a folder called nginx):

version: "3.7"
volumes:
  xmpl:

services:
  testnginx:
    image: nginx:stable
    volumes:
      - xmpl:/etc/nginx

将通过以下方式产生 host 系统上的所有文件：

Will yield all the files on the host system via:

$ docker-compose up
$ docker inspect nginx_xmpl
...
"Mountpoint": "/var/lib/docker/volumes/nginx_xmpl/_data"

然后您可以在主机上查看文件：

And you can then view the files on the host:

# ls /var/lib/docker/volumes/nginx_xmpl/_data
  conf.d       fastcgi_params koi-utf    koi-win
  mime.types   modules        nginx.conf scgi_params
  uwsgi_params win-utf

最后在 ./ config中使用它。 em>：

And finally to use it from ./config:

# ln -s /var/lib/docker/volumes/nginx_xmpl/_data ./config
# ls config
  conf.d       fastcgi_params koi-utf    koi-win
  mime.types   modules        nginx.conf scgi_params
  uwsgi_params win-utf
