我想创建一个包含三个节点和一个共享卷的 Swarm 集群（在 Windows 10 中）。我使用docker-machine：
docker-machine create -d virtualbox swarm1-mgr1
docker-machine create -d virtualbox swarm1-wrk1
docker-machine create -d virtualbox swarm1-wrk2
接下来我初始化一个管理节点：
docker-machine ssh swarm1-mgr1 docker swarm init
并添加工作人员：
docker-machine ssh swarm1-wrk1 docker swarm join --token ...
docker-machine ssh swarm1-wrk2 docker swarm join --token ...
接下来，我将控制台配置为与管理器节点一起使用：
docker-machine ssh swarm1-mgr1 "docker node ls"
docker-machine env swarm-mgr1
& "C:\ProgramData\chocolatey\lib\docker-machine\bin\docker-machine.exe" env swarm-mgr1 | Invoke-Expression
然后我创建了一个寄存器：
docker service create --name registry --publish 5006:5000 registry:2
docker-compose build
docker push localhost:5006/web
最后我正在尝试部署我的应用程序：
docker stack deploy -c docker-compose.yml stack_1
docker service ps stack_1_web --no-trunc
但收到下一条错误消息：

我不明白为什么 Swarm 看不到我的音量。任何帮助将不胜感激。我的最终目标是在具有一个共享卷的三个节点上部署堆栈。

UPD：我尝试在 Lunix VM 中做同样的事情，但我遇到了同样的错误
