创建一个Docker Swarm v1.12.3服务并挂载NFS卷 [英] create a Docker Swarm v1.12.3 service and mount a NFS volume

问题描述

我无法为Docker Swarm挂载NFS卷，并且缺少有关--mount语法的适当官方文档(

I'm unable to get a NFS volume mounted for a Docker Swarm, and the lack of proper official documentation regarding the --mount syntax (https://docs.docker.com/engine/reference/commandline/service_create/) doesnt help.

我基本上已经尝试过使用以下命令行来创建一个简单的nginx服务，其中将/kkk目录安装到NFS卷上:

I have tried basically this command line to create a simple nginx service with a /kkk directory mounted to an NFS volume:

docker服务创建--mount type = volume，src = vol_name，volume-driver = local，dst =/kkk，volume-opt = type = nfs，volume-opt = device = 192.168.1.1:/your/nfs/path --name测试nginx

docker service create --mount type=volume,src=vol_name,volume-driver=local,dst=/kkk,volume-opt=type=nfs,volume-opt=device=192.168.1.1:/your/nfs/path --name test nginx

命令行被Swarm接受并且服务由Swarm调度，但是容器从未达到运行"状态，并且Swarm每隔几秒钟就会尝试启动一个新实例.我将守护程序设置为调试，但有关卷显示没有错误...

The command line is accepted and the service is scheduled by Swarm, but the container never reaches "running" state and swarm tries to start a new instance every few seconds. I set the daemon to debug but no error regarding the volume shows...

使用NFS卷创建服务的正确语法是什么?

Which is the right syntax to create a service with a NFS volume?

非常感谢

推荐答案

我在这里找到了一篇文章，展示了如何安装nfs共享(并且对我有用):

I found an article here that shows how to mount nfs share (and that works for me): http://collabnix.com/docker-1-12-swarm-mode-persistent-storage-using-nfs/

sudo docker service create \
--mount type=volume,volume-opt=o=addr=192.168.x.x,volume-opt=device=:/data/nfs,volume-opt=type=nfs,source=vol_collab,target=/mount \
--replicas 3 --name testnfs \
alpine /bin/sh -c "while true; do echo 'OK'; sleep 2; done"

更新:
如果要与docker-compose一起使用，可以执行以下操作:

Update:
In case you want to use it with docker-compose you can do it the following:

version: '3'

services:

  alpine:
    image: alpine
    volumes:
      - vol_collab:/mount
    deploy:
      mode: replicated
      replicas: 2
    command: /bin/sh -c "while true; do echo 'OK'; sleep 2; done"


volumes:
  vol_collab:
    driver: local
    driver_opts:
      type: nfs
      o: addr=192.168.xx.xx
      device: ":/data/nfs"

然后使用

docker stack deploy -c docker-compose.yml test
