+## Configuration
+
+Configuration de différentes manières :
+- ansible.cfg
+- cli
+
+Et à différents endroits pour ansible.cfg (ordre inverse de prise en compte)
+
+- éventuellement en définissant ANSIBLE_CONFIG
+- à l'endroit de votre playbook ansible.cfg
+- ~/.ansible/ansible.cfg
+- /etc/ansible/ansible.cfg
+
+
+
+
+
+Exemple :
+```bash
+inventory       = /etc/ansible/hosts
+forks           = 5
+sudo_user       = root
+ask_sudo_pass   = True
+ask_pass        = True
+gathering       = implicit
+gather_subset   = all
+roles_path      = /etc/ansible/roles
+log_path        = /var/log/ansible.log
+vault_password_file = /path/to/vault_password_file
+fact_caching_connection =/tmp
+pipelining = False
+```
+Doc : https://docs.ansible.com/ansible/2.3/intro_configuration.html
+
+Commande :
+
+ansible-config
+ansible-config view  # voir le ansible.cfg pris en compte
+ansible-config list  # toute les variables et leurs valeurs
+cf : https://docs.ansible.com/ansible/latest/reference_appendices/config.html
+
+ansible-config dump  # liste toutes les variables ansible
+ansible-config dump --only-changed #valeurs par défaut modifiée

+ANSIBLE_SSH_ARGS:
+  default: -C -o ControlMaster=auto -o ControlPersist=60s
+  description:
+  - If set, this will override the Ansible default ssh arguments.
+  - In particular, users may wish to raise the ControlPersist time to encourage performance.  A
+    value of 30 minutes may be appropriate.
+  - Be aware that if `-o ControlPath` is set in ssh_args, the control path setting
+    is not used.
