Docker Compose 到 CoreOS

Question

我目前正在学习 Docker，并制作了一个简单易用的 Docker Compose 设置。 3 个容器，都有自己的 Dockerfile 设置。我如何才能将其转换为在 CoreOS 上工作，以便稍后设置集群？

web:
  build: ./app
  ports:
    - "3030:3000"
  links:
    - "redis"

newrelic:
  build: ./newrelic
  links:
    - "redis"

redis:
  build: ./redis
  ports:
    - "6379:6379"
  volumes:
    - /data/redis:/data

取自 https://docs.docker.com/compose/install/

唯一的问题是/usr 是只读的，但/opt/bin 是可写的并且在路径中，所以:

sd-xx~ # mkdir /opt/
sd-xx~ # mkdir /opt/bin
sd-xx~ # curl -L https://github.com/docker/compose/releases/download/1.3.3/docker-compose-`uname -s`-`uname -m` > /opt/bin/docker-compose

sd-xx~ # chmod +x /opt/bin/docker-compose
