Windows 10绑定在docker-compose中的安装不起作用 [英] Windows 10 bind mounts in docker-compose not working

问题描述

我正在使用docker-compose管理多容器应用程序。这些容器中的1个需要访问主机上目录的内容。

I'm using docker-compose to manage a multi container application. 1 of those containers needs access to the contents of a directory on the host.

根据docker和docker-compose的各种文档来源，这似乎很简单，但我我努力使它正常工作。

This seems simple according to the various sources of documentation on docker and docker-compose but I'm struggling to get it working.

  event_processor:
    environment:
      - COMPOSE_CONVERT_WINDOWS_PATHS=1
    build: ./Docker/event_processor
    ports:
      - "15672:15672"
    entrypoint: python -u /src/event_processor/event_processor.py
    networks:
      - app_network
    volumes:
      - C/path/to/interesting/directory:/interesting_directory"

正在运行这我得到错误消息：

Running this I get the error message:

错误：命名卷
C / path / to / interesting / directory：/ interesting_directory ：rw用于
服务 event_processor，但未在
卷部分中找到声明。

ERROR: Named volume "C/path/to/interesting/directory:/interesting_directory:rw" is used in service "event_processor" but no declaration was found in the volumes section.

我从文档中了解到，仅当要获取数据时才需要顶层声明在容器之间共享

在这里不是这种情况。

我在上面链接的docker-compose文档中有一个示例似乎完全满足我的需要：

The docs for docker-compose I linked above have an example which seems to do exactly what I need:

version: "3.2"
services:
  web:
    image: nginx:alpine
    ports:
      - "80:80"
    volumes:
      - type: volume
        source: mydata
        target: /data
        volume:
          nocopy: true
      - type: bind
        source: ./static
        target: /opt/app/static

networks:
  webnet:

volumes:
  mydata:

但是，当我尝试时，会出现语法错误：

However when I try, I get errors about the syntax:

错误：撰写文件'.\docker-compose.yaml'无效，因为：
services.audio_event_processor.volumes包含无效类型，它
应该是一个字符串

ERROR: The Compose file '.\docker-compose.yaml' is invalid because: services.audio_event_processor.volumes contains an invalid type, it should be a string

所以我试着玩：

volumes:
  - type: "bind"
    source: "C/path/to/interesting/directory"
    target: "/interesting_directory"

错误：撰写文件。 \docker-compose.yaml'无效，因为：
services.audio_event_processor.volumes包含无效类型，应为字符串

ERROR: The Compose file '.\docker-compose.yaml' is invalid because: services.audio_event_processor.volumes contains an invalid type, it should be a string

因此再次相同错误。

我也尝试了以下操作：

volumes:
  - type=bind, source=C/path/to/interesting/directory,destination=/interesting_directory

没有错误，但附加到正在运行的容器，我看到以下两个文件夹；

No error, but attaching to the running container, I see the following two folders;

type=bind, source=C

所以看来我能够用1个字符串创建许多卷（尽管向前在这种情况下，斜杠会截断字符串），但我没有将其映射到主机目录。

So it seems that I am able to create a number of volumes with 1 string (though the forward slashes are cutting the string in this case) but I am not mapping it to the host directory.

我已经阅读了文档，但是我想缺少一些东西。
有人可以举一个将Windows目录从主机安装到Linux容器的示例，以便可以从容器中获取Windows目录的现有内容吗？

I've read the docs but I think I'm missing something. Can someone post an example of mounting a a windows directory from a host to a linux container so that the existing contents of the windows dir is available from the container?

推荐答案

好，所以这里有多个问题：

OK so there were multiple issues here:

1。

我有

version: '3'

在我的docker-compose.yml顶部。在此处描述的长语法直到才实现因此，当我将其更新为：

at the top of my docker-compose.yml. The long syntax described here wasn't implemented until 3.4 so I stopped receiving the bizarre syntax error when I updated this to:

version: '3.6'

2。

我在2台Windows PC上使用我的docker帐户。在另一个stackoverflow帖子中提示之后，我将Docker重置为出厂设置。我必须给docker计算机的用户名和密码，并注意这是访问本地文件系统的内容所必需的-此时，我记得在另一台PC上进行了此操作，因此我不确定凭据在此是否正确。有了当前PC的正确凭据，我就可以将卷与预期结果绑定安装，如下所示：

I use my my docker account on 2 windows PCs. Following a hint from another stackoverflow post, I reset Docker to the factory settings. I had to give docker the computer username and password with the notice that this was necessary to access the contents of the local filesystem - at this point I remembered doing this on another PC so I'm not sure whether the credentials were correct on this on. With the correct credentials for the current PC, I was able to bind-mount the volume with the expected results as follows:

   version: '3.6'

   event_processor:
    environment:
      - COMPOSE_CONVERT_WINDOWS_PATHS=1
    build: ./Docker/event_processor
    ports:
      - "15672:15672"
    entrypoint: python -u /src/event_processor/event_processor.py
    networks:
      - app_network
    volumes:
      - type: bind
        source: c:/path/to/interesting/directory
        target: /interesting_directory

现在它可以按预期工作。我不确定是修复了出厂设置还是更新了凭据。明天我会在使用另一台PC进行更新时找到答案。

Now it works as expected. I'm not sure if it was the factory reset or the updated credentials that fixed it. I'll find out tomorrow when I use another PC and update.
