using ansible, i want to stop all running docker container except for the container whose name I will specify

I have tried to get the container info

    - name: Get info on docker host and list images
      docker_host_info:
        containers: yes
      register: docker_info

    - name: Stop running docker containers
      docker_container:
        name: '{{ item.Names.0}}'
        state: stopped
      loop: '{{ docker_info.containers }}'
      when: ??

the when condition is what I’m not sure how to do?
Im still new to ansible, hope someone give me advice
