使用Ansible和Docker部署/运行Redis服务
我正在使用Ansible docker模块来设置Redis服务（请参阅下面的安全angular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 configuration完成后， redis-service容器已经启动，但是当我尝试使用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似乎正在运行：
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
你有什么想法可能会导致这个问题？
我终于find了问题： ports属性也必须设置（不仅仅是暴露 ）
- 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
