Question

我正在使用Ansible docker module设置Redis服务（请参阅下面的ansible角色）

- hosts: redis
  roles:
  - role: angstwad.docker_ubuntu
    sudo: true
  tasks:
  - name: data container
    sudo: true
    docker:
      name: redis-data
      image: busybox
      state: started
      volumes:
       - /data/redis
  - name: redis container
    sudo: true
    docker:
      name: redis-service
      image: redis:3
      command: redis-server --appendonly yes
      state: started
      expose: 6379
      volumes_from:
       - redis-data

配置完成后，redis-service容器已启动，但当我尝试使用redis-cli连接到redis时出现以下错误：

vagrant@dev1:~$ redis-cli
Could not connect to Redis at 127.0.0.1:6379: Connection refused

注意：redis-service似乎正常运行：

vagrant@dev1:~$ docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS               NAMES
3e8f27b14479        redis:3             "/entrypoint.sh redis"   12 minutes ago      Up 12 minutes       6379/tcp            redis-service

vagrant@dev1:~$ docker logs 3e8f27b14479
...
1:M 02 Sep 15:41:16.532 * The server is now ready to accept connections on port 6379

你知道可能导致问题的原因吗？

我终于找到了问题：端口属性也必须设置（不仅公开）

- hosts: redis
  roles:
  - role: angstwad.docker_ubuntu
    sudo: true
  tasks:
  - name: data container
    sudo: true
    docker:
      name: redis-data
      image: busybox
      state: started
      volumes:
       - /data/redis
  - name: redis container
    sudo: true
    docker:
      name: redis-service
      image: redis:3
      command: redis-server --appendonly yes
      state: started
      expose: 6379
      ports:
       - 6379:6379
      volumes_from:
       - redis-data

使用Ansible和Docker部署/运行Redis服务
