Deploy/run a Redis service using Ansible and Docker - redis

Question

I'm using Ansible docker module to setup a Redis service (see ansible role below)
- 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
After provisioning, redis-service container is up but when I try to connect to redis using redis-cli I have the following error:
vagrant#dev1:~$ redis-cli
Could not connect to Redis at 127.0.0.1:6379: Connection refused
NOTE: redis-service seems up and running:
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
Do you have any idea of what might cause the problem?

Answer 1

I finally found the problem: ports attribute must be set too (not only expose)
- 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
