Using the Ansible docker_service module to deploy a service for a swarm

Question

I'm trying to deploy a Docker service in a swarm, but always ending up with a running container on my local host (the one I use as the docker roaming manager) and no service

Here is my setup:

I have 3 node Docker (v.1.12.1) swarm, which includes one host working as a manager, and two work nodes, all of which work in CentOS 7. On the manager node (localhost) launched Ansible (v. 2.1.1.0) playbook, and the swarm is already configured and working

Swarm: active
 NodeID: d9h5xa832ax7wzeq8q44fjld3
 Is Manager: true
 ClusterID: 9cztoin3gy2ntbwehsmrkjuxi
 Managers: 1
 Nodes: 3
 Orchestration:
  Task History Retention Limit: 5
 Raft:
  Snapshot Interval: 10000
  Heartbeat Tick: 1
  Election Tick: 3
 Dispatcher:
  Heartbeat Period: 5 seconds
 CA Configuration:
  Expiry Duration: 3 months
 Node Address: 10.25.190.209

Starting with a tutorial having this code

- hosts: localhost
  name: Run JMeter test
  vars_files:
    - user.config.yml
  vars:
    execute_tpcds_test : "{{ run_tpcds_test }}"    
  roles:
    - { role: run_jmeter, when: execute_tpcds_test is defined and execute_tpcds_test ==1 }

What causes this role:

- name: Deploy tpcds_tpg service to swarm
  docker_service:
    project_name: tpcds-tpg
    definition:
      version: '2'
      services:
        run_tests: 
          image: 'pbench/tpcds_tpg'
          volumes: 
            - /opt/pbench/run_output/
          command: ./run_jmeter.sh "{{jmeter_output_dir}}" 
  register: output
- debug: var=output

When I start ansible-playbook ./site.yml, I end up with a running container. Execution docker ps -adisplays

[pdo@sdl02133 tpcds-tpg]$ docker ps -a
CONTAINER ID        IMAGE              COMMAND                  CREATED             STATUS              PORTS               NAMES
