+# ANSIBLE
 
-## Provisionning
+## How to proceed
 
- 1. Need a public IP address
- 2. Deploy Debian sid/buster
- 3. Add a DNS entry like xxxx.machine.deuxfleurs.fr A 0.0.0.0 in Cloudflare + Havelock
- 4. Setup the fqdn in /etc/hosts (127.0.1.1 xxxx.machine.deuxfleurs.fr)
- 5. Switch the SSH port to the port 110
- 6. Add the server to the ./production file 
- 7. Reboot machine
- 8. Deploy Ansible
- 9. Check that everything works as intended
- 10. Update NS 1.cluster.deuxfleurs.fr
-
-## Useful commands
-
-Show every variables collected by Ansible for a given host:
-
-```
-ansible -i production villequin.machine.deuxfleurs.fr -m setup
-```
-
-Run playbook for only one host:
-
-```
-ansible-playbook -i production --limit villequin.machine.deuxfleurs.fr site.yml
-```
-
-Dump hostvars:
-
-```
-ansible -m debug villequin.machine.deuxfleurs.fr -i ./production -a "var=hostvars"
-```
-
-Deploy only one tag:
-
-```
-ansible-playbook -i production site.yml --tags "container"
-```
-
-Redeploy everything:
-
-```
-ansible-playbook -i production site.yml
-```
-
-Upgrade packages and force overwirte to fix bad packing done by GlusterFS:
-
-```
-apt-get -o Dpkg::Options::="--force-overwrite"  dist-upgrade -y
-```
+For each machine, **one by one** do:
+  - Check that cluster is healthy
+  - Run `ansible-playbook -i production --limit <machine> site.yml`
+  - Reboot
+  - Check that cluster is healthy
