使用docker-compose

Question

我的场景

我正在尝试使用docker-compose.yml文件

构建docker swarm

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

我的系统有Docker Version 17.03.1-ce-mac5 (16048)

问题

卷安装不起作用，如果我注释掉volumes: - ./nginx/certs:/etc/nginx/certs，那么一切正常。

否则nginx根本不起作用，我看

在docker-compose v3中安装卷有什么特殊方法吗？

Answer 1

安装卷时必须使用绝对路径，也可以使用 docker run 。

$ docker run --rm -it -v ./eos:/eos:ro ubuntu 
docker: Error response from daemon: create ./eos: "./eos" includes invalid characters for a local volume name, only "[a-zA-Z0-9][a-zA-Z0-9_.-]" are allowed. If you intented to pass a host directory, use absolute path.
See 'docker run --help'

Answer 2

我在macbook上运行docker stack deploy而不是在boot2docker VM上运行。这就是系统无法找到那些网络安装源的原因，即使我使用eval $(docker-machine env manager1)

激活了manager1

首先，我使用了--no-trunc参数来查看完整的错误消息。

$> 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并启动堆栈工作正常。
