  name: BDII_TOP plays
  pre_tasks:
    - debug:
        msg: "Site is  {{ site_name }}"
      tags:
        - debug

    - name: Tell the team
      slack:
        domain: africa-arabia-roc.slack.com
        token: {{ slack_token }}
        msg: "Running top-bdii play at on {{ ansible_hostname }} at {{ site_name }}"
        username: "Ansible on {{ ansible_hostname }} at {{ site_name }}"

The yaim role is applied in order to ensure that the right configuration is generated via templates and the execution of the configuration via yaim is performed. See the yaim role for more information.

      tags:
