I am a newbie with ansible, I am trying to spin up a docker container with the following command

`

- name: Swarm node is running  
docker:  
docker\_api\_version: 1.18  
name: swarm-node  
image: swarm  
command: join --addr={{ ip }}:2375 token://{{ swarm\_cluster\_token }}  
state: restarted  
when: not swarm\_master is defined  
register: docker\_cmd  
tags: [swarm]  
`

I see that the variables are not expand for {{ ip }} and {{ swarm\_cluster\_token }}, when i tried debug the variables i see they are available inside the playbook.

I tried doing the following options:

`'join --addr="{{ ip }}":2375 token://"{{ swarm_cluster_token }}"'`

I am using the ansible 1.9.2 , docker v1.7.1, docker-py: 1.3.1 but pinned the version of the docker api to 1.18 to circumvent the issue posted [https://github.com/ansible/ansible-modules-core/issues/1707](https://github.com/ansible/ansible-modules-core/issues/1707)

Still with the same result, any thoughts why the variables are not getting expanded inside the docker command ?

Cheers,  
Kamesh

Sorry for this issue, after debugging i understood for docker-swarm the ip is just used for addressing and its not listed with docker ps , when I inspected the node I see the IP getting passed correctly.
