Docker Swarm和Windows节点持久存储

Question

我们有一个Docker Swarm cluster，其中有Linux和Windows个节点。

当前我们使用Docker version 19.03.1, build 74b1e89。

在Linux节点上，我们使用NFS存储，但是在Windows节点上似乎无法实现。

到目前为止我们尝试过的事情：

• 创建nfs volume会导致错误options are not supported on this platform

• 设置nfs共享之前启动服务会给出错误invalid volume specification … invalid mount config for type "bind" … source path does not exist ...

• 使用SMB Global Mapping会显示错误The parameter is incorrect

为SMB Global Mapping创建了V:的共享

$secpasswd = ConvertTo-SecureString 'test' -AsPlainText -Force
$creds = New-Object System.Management.Automation.PSCredential ("test", $secpasswd)
New-SmbGlobalMapping -RemotePath \\192.168.100.100\tmp -Credential $creds -LocalPath V:

并使用以下docker-compose：

version: '3.7'

services:
  smb:
    image: mcr.microsoft.com/windows/servercore/iis:windowsservercore-1903
    volumes:
      - V:\poc:C:\inetpub\wwwroot
    ports:
      - 8080:80
    networks:
      - default

networks:
  default:

这是错误消息：

有人对如何在Docker Swarm集群中的Windows节点上使用持久性存储有解决方案吗？

Answer 1

按照＃3所述运行powershell命令之前，需要在Windows功能中启用SMB文件共享。

启用此功能后，请确保共享文件夹并添加必要的安全权限。

这之后必须运行以下命令

1. $ creds =获取凭据

2. New-SmbGlobalMapping -RemotePath \ SERVER \ SharePath $ creds -LocalPath驱动器：
