Windows容器中Docker Compose命名卷无法正常工作问题

问题详情 #

尝试配置Docker Compose使用命名卷在Windows容器间共享文件时，启动容器报错The request is not supported。使用的docker-compose.yml配置如下：

version: "3.9"

services:
  nano:
    image: mcr.microsoft.com/windows/nanoserver:1809
    volumes:
      - test-data:C:/test-data
volumes:
  test-data:
    name: test-data

执行时的错误日志：

[+] Running 2/3
 - Network test_default   Created                                                                                                 0.8s

is not supported.

但直接通过Docker命令行启动容器却能正常运行，容器间可正常共享文件：

docker run -it --rm -v test-data:C:/test-data mcr.microsoft.com/windows/nanoserver:1809 cmd

修复方案 #

这是Docker Compose的已知问题，只需将容器内的挂载路径改为小写格式即可解决。修正后的docker-compose.yml如下：

version: "3.9"

services:
  nano:
    image: mcr.microsoft.com/windows/nanoserver:1809
    volumes:
      - test-data:c:/test-data  # 大写C改为小写c
volumes:
  test-data:
    name: test-data
