+# ANSIBLE
+
+## How to proceed
+
+For each machine, **one by one** do:
+  - Check that cluster is healthy
+    - `sudo gluster peer status`
+    - `sudo gluster volume status all` (check Online Col, only `Y` must appear)
+    - Check that Nomad is healthy
+    - Check that Consul is healthy
+    - Check that Postgres is healthy
+  - Run `ansible-playbook -i production --limit <machine> site.yml`
+  - Reboot
+  - Check that cluster is healthy
+

+
+## Provisionning
+
+ 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
+```
