我已经将Rails应用程序（本地开发机）迁移到Docker-Compose。除Worker Rails实例（批次）无法连接到Redis之外，其他所有组件都在工作。

Completed 500 Internal Server Error in 40ms (ActiveRecord: 2.3ms)

Redis::CannotConnectError (Error connecting to Redis on 127.0.0.1:6379 (Errno::ECONNREFUSED)):

在我的docker-compose.yml中

redis:
  image: redis
  ports:
    - "6379:6379"

batch:
  build: .
  command: bundle exec rake environment resque:work QUEUE=*
  volumes:
    - .:/app
  links:
    - db
    - redis
  environment:
    - REDIS_URL=redis://redis:6379

我认为Redis实例可通过Docker主机的IP获得。

$ docker-machine ls
NAME      ACTIVE   DRIVER       STATE     URL                       SWARM   DOCKER    ERRORS
default   *        virtualbox   Running   tcp://192.168.99.100:2376           v1.10.0

通过0.0.0.0访问不起作用

$ curl 0.0.0.0:6379 
curl: (7) Failed to connect to 0.0.0.0 port 6379: Connection refused …
