Question

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。

这是我的docker-compose.yml：

version: '3.3'
services:
    web:
        image: localhost:5006/web:latest
        build:
            context: .
            dockerfile: Dockerfile
        ports:
            - "5000:5000"
        depends_on:
            - redis
        deploy:
            replicas: 1
        networks:
            - webnet
        volumes:
            - compose_flask_1:/compose_flask_1

    redis:
        image: redis
        networks:
            - webnet
        deploy:
            placement:
                constraints:
                    - 'node.role==manager'

    visualizersvc:
        image: dockersamples/visualizer
        depends_on:
            - redis
        deploy:
            placement:
                constraints:
                    - 'node.role==manager'
        ports:
            - '5001'
        volumes:
            - '/var/run/docker.sock:/var/run/docker.sock'
        networks:
            - webnet

networks:
    webnet:
        driver: overlay
        attachable: true

volumes:
    compose_flask_1:
        driver: local
        driver_opts:
            type: nfs
            o: nfsvers=4,addr=localhost,rw
            device: ":F:/desktop/test/compose_flask_1"

Dockerfile：

FROM python:2.7
ADD . /code
WORKDIR /code
RUN pip install -r requirements.txt
CMD python ./app.py

requirements.txt：

flask
redis

和app.py：

from flask import Flask
from redis import Redis
app = Flask(__name__)
redis = Redis(host='redis', port=6379)
@app.route('/')
def hello():
    redis.incr('hits')
    return 'Flask demo 1 has been viewed %s time(s).' % redis.get('hits')
if __name__ == "__main__":
    app.run(host="0.0.0.0", debug=True)

UPD：我尝试在 Lunix VM 中做同样的事情，但我遇到了同样的错误

Docker Swarm 和 NFS 卷（启动容器失败：挂载时出错；卷无法挂载本地卷）
