使用docker-compose发出安装docker volume的问题 [英] Issue mounting docker volume with docker-compose

问题描述

我正在尝试使用 docker-compose.yml 文件构建docker swarm

I am trying to build docker swarm with docker-compose.yml file

version: '3'

services:
  myapp-nginx:
    image: nginx:1.10
    volumes:
     - ./nginx/certs:/etc/nginx/certs
    ports:
      - 80:80
      - 443:443

使用以下构建命令

$ docker stack deploy --compose-file docker-compose.yml myapp

Creating network myapp_default
Creating service myapp_myapp-nginx

我的系统具有 Docker版本17.03.1-ce-mac5（16048）

卷装载不起作用，如果我注释掉卷：-./ nginx / certs：/ etc / nginx / certs ，然后一切正常。

Volumes mounts are not working, If I comment out volumes: - ./nginx/certs:/etc/nginx/certs then everything works fine.

否则，nginx根本不起作用 p>

Otherwise nginx doesn't work at all, I see

CAGTAM1059934:docker iskumar$ docker stack ps myapp
ID            NAME                  IMAGE       NODE      DESIRED STATE  CURRENT STATE            ERROR                             PORTS
efjia8b7y6jd  myapp_myapp-nginx.1      nginx:1.10  manager1  Ready          Rejected 5 seconds ago   "invalid mount config for type…"  
c9c6ogh11osi   \_ myapp_myapp-nginx.1  nginx:1.10  worker2   Shutdown       Rejected 10 seconds ago  "invalid mount config for type…"  
iveikxpnbq6x   \_ myapp_myapp-nginx.1  nginx:1.10  worker1   Shutdown       Rejected 15 seconds ago  "invalid mount config for type…"  

是否有任何特殊的方式在docker-compose v3中装载卷？

Is there any special way to mount volumes in docker-compose v3?

推荐答案

我是从macbook运行 docker stack deploy 而不是在boot2docker VM上运行的。这就是为什么即使我使用 eval $（docker-machine env manager1）

I was running docker stack deploy from my macbook instead on boot2docker VMs. Which is why system couldn't find those network mount source, even though I had manager1 activated using eval $(docker-machine env manager1)

首先，我使用--no-trunc参数查看完整的错误消息。

First I used --no-trunc argument to view full error message.

$> docker node ps --no-trunc
---
Showed "invalid mount config for type "bind": bind source path does not exist"  
---

之后，将文件从主机系统（ My MacBook ）复制到VM，启动堆栈工作正常。

After that copies the files from host system (My MacBook) to VM and launching stack worked fine.
