 +Correspond à Ansible et est installé par :
 +~~~bash
 +sudo yum install ansible

 +Control node
 +* control plane 
 +* execution plane
 +
 +Dans AAP v1 le "control plane" et l'"execution plane" étaient ensemble sur le "control node"
 +
 +mesh node types :
 +`node_type=hybrid` par défaut ou `node_type=control`
 +
 +node_type :
 +  * control (WebUI & API)
 +  * execution (ansible-playbook)
 +  * hybrid (Execution + control)
 +  * hop (sorte de proxy ssh entre le Controller et les Execution Nodes ; ne peut pas être un Execution Node)

 +Anciennement "Isolated Nodes"
 +
 +Voir :
 +* https://developers.redhat.com/blog/2017/12/20/understanding-ansible-tower-isolated-nodes#
 +
 +Alternative à ssh-proxy\\
 +The only prerequisite is that there is SSH connectivity from the Tower Cluster to the Isolated Node
 +
 +Exemple de conf :
 +~~~ini
 +[isolated_group_restrictedzone:vars]
 +controller=tower
 +
 +[isolated_group_nc]
 +cary.remote.office controller=tower
 +~~~
 +
 +Isolated instances are not supported in conjunction with running Ansible Tower in OpenShift.

 +extra_vars des jobs dans les logs (à tester)
 +~~~yaml
 +- hosts: localhost
 +  gather_facts: false
 +  tasks:
 +    - shell: "echo {{ inventory_hostname }}"
 +~~~
 +
 +ou
 +
 + The first idea was to add extra_vars to every job events, but it would work just as well to be able to add a short string label (prompt on launch) when launching a job template. This should not cause a performance issue.
 +
 +Add extra_vars to every job event sent over job_events #11330
