Correspond à Ansible et est installé par :

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)

The machine that runs Ansible Linux Mac BSD … Python 3.8 ou +

mesh node types node_type=hop ou node_type=execution

work-signing keys

Control node receptor

- work-signing:
    privatekey: /etc/receptor/work_private_key.pem
    tokenexpiration: 1m

- work-verification:
    publickey: /etc/receptor/work_public_key.pem

Execution Node

- work-verification:
    publickey: /etc/receptor/work_public_key.pem

To create the keys, just do openssl commands, you can see them evokes in the plays here https://github.com/ansible/awx/blob/a86740c3c9eaf9a551e850341d8adec5a3962dd5/tools/docker-compose/ansible/roles/sources/tasks/main.yml#L84

Automation Hub / Galaxy

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 :

[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)

- 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
