How to a activate ONOS apps by ansible-playbook?

[Ivy Min]

My ansible-playbook version is latest. I try to activate ONOS service in docker container by running ansible-playbook. I tried some ways. However they all failed.

---
- hosts: local
  tasks:
  - name: Create a onos-a container
    docker_container:
      name: onos-a
      image: onosproject/onos 
      restart: yes
      ports: 8190:8190 

  - name: Activate onos-a fwd apps #failed by shell
    shell: "docker exec -it onos-a bash -c '/root/onos/apache-karaf-4.2.6/bin/client app activate org.onosproject.openflow'"
    become: yes
  - name: Activate onos-a apps #fialed by commands
    docker_container:
       name: onos-a
       command: export ONOS_APPS=fwd
       command: export ONOS_APPS=openflow

Need some help ~

when I running shell command, the error shows

   "changed": true, 
    "cmd": "sudo docker exec -it onos_b bash -c '/root/onos/apache-karaf-4.2.6/bin/client app activate org.onosproject.openflow'",

        "Failed to get the session."
    ]
}

When I ssh to the sever running commands, shows

onos-b:~$ sudo docker exec -it onos_b bash -c '/root/onos/apache-karaf-4.2.6/bin/client app activate org.onosproject.fwd'
Logging in as karaf
Activated org.onosproject.fwd
