 # RVN - TP2.2 : Ordonnancement de services sur une grappe
 
 1. Provisionner des VMs **sur notre WAN** avec [Vagrant](https://developer.hashicorp.com/vagrant/docs)
-2. Déployer un cluster [Consul](https://developer.hashicorp.com/consul/docs)
+2. Déployer [Consul](https://developer.hashicorp.com/consul/docs) et [Nomad](https://developer.hashicorp.com/nomad/docs) 
-3. Déployer un service avec Docker et le surveiller avec Consul

-4. Déployer des services avec [Nomad](https://developer.hashicorp.com/nomad/docs)

 ## 1. Provisionner des VMs
 
+1. Vérifiez le bon fonctionnement de notre WAN
+2. Écrivez chacun un [Vagrantfile](./Vagrantfile) pour lancer une VM sur le WAN, en suivant le schéma d'adressage suivant :
+
 | Continent| IP sur continent   | IP VM            |
 |--------- | ------------------ | ---------------- |
 | Amerique | `10.13.1.3/24`     | `10.13.1.31/24` |
 | Europe   | `10.13.2.1/24`     | `10.13.2.11/24` |
 | Asie     | `10.13.3.4/24`     | `10.13.3.41/24` |

+## 2. Déployer Consul et Nomad
-* [./install_nomad_consul.sh](./install_nomad_consul.sh)
+
+1. Modifiez votre `Vagrantfile` pour qu'il provisionne votre VM avec [Consul](https://developer.hashicorp.com/consul/docs) et [Nomad](https://developer.hashicorp.com/nomad/docs)
+
+    Vous pouvez aussi lancer des scripts sur les VMs sans rebooter, par exemple avec :
+       
+        ssh ... ENV=xxx 'bash -s' < script.sh 
+
+Inspiration : [./install_nomad_consul.sh](./install_nomad_consul.sh)
+
+Chaque continent est un "datacenter" : `am`, `eu`, `as`. Il nous faut un Consul/Nomad serveur par zone géographique, les autres sont clients (configuration manuelle dans les `.hcl`).
+
+## Docs 
+
+### Consul
+
+* Follow this guide to provision a Vagrant VM with Consul: https://developer.hashicorp.com/consul/tutorials/certification-associate-tutorials/get-started-create-datacenter
+
+* Vagrant can auto-install Docker if you ask it to run containers: https://developer.hashicorp.com/vagrant/docs/provisioning/docker
+
+* Deployment guide: https://developer.hashicorp.com/consul/tutorials/production-deploy/deployment-guide
+
+* Register services to Consul: https://developer.hashicorp.com/consul/tutorials/get-started-vms/virtual-machine-gs-service-discovery
+
+### Nomad
