来自守护程序的错误响应：无法识别的卷规范：无法映射文件“\\.\pipe\docker_engine”。该平台上只能映射目录

Question

我是码头工人的新手。欢迎任何帮助和提示。

\n

环境：

\n

\n
• Windows：Windows 10 专业版 21H1
\n
• Docker 桌面：3.4
\n

\n

我可以毫无问题地运行 hello work 示例。但似乎我无法使用命名管道，无法弄清楚问题是什么。

\n

有些人提到命名管道仅适用于 Windows 服务器，但此博客（https://www.docker.com/blog/docker-windows-server-1709/）明确提到支持 Windows 10。

docker版本输出：

YAML 文件：

\n

如果我删除了卷中的命名管道，我可以创建容器，然后出现不同的错误：

\n

time="2021-06-17T06:32:13+08:00" level=error msg="Provider connection error error during connect: This error may indicate that the docker daemon is not running.: Get \\"http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/version\\": open //./pipe/docker_engine: The system cannot find the file specified., retrying in 7.701954985s" providerName=docker\n

\n

其余容器运行正常。

Answer 1

使用 Docker Compose V2 时会出现此错误。关闭 Docker Desktop 设置中的选项或使用 CLI 命令docker-compose disable-v2。

Answer 2

我遇到了同样的错误，我的解决方案是在末尾添加一个 \ 。
