+# Installation de Terraform et initialisation de son premier répertoire de travail
+
+Avant de pouvoir profiter de ce merveilleux outil, il faut définir sur quel environnement de travail vous souhaitez l'utiliser.
+
+Il existe plusieurs méthodes pour ce faire, je ne vais pas toutes les citer. Ici, il ne s'agira que de son installation sur un environnement Linux Debian/Ubuntu. Pour les autres systèmes, je vous invite à consulter la [documentation officielle](https://developer.hashicorp.com/terraform/tutorials/aws-get-started/install-cli)
+
+# Installation sur une Debian 11
+
+## Installation des paquets préliminaires 
+```bash
+sudo apt-get update && sudo apt-get install -y gnupg software-properties-common
+```
+
+## Installation de la clef GPG de Hashicorp
+```bash
+wget -O- https://apt.releases.hashicorp.com/gpg | \
+gpg --dearmor | \
+sudo tee /usr/share/keyrings/hashicorp-archive-keyring.gpg
+```
+
+### Vérification de la clef de sécurité
+```bash
+gpg --no-default-keyring \
+--keyring /usr/share/keyrings/hashicorp-archive-keyring.gpg \
+--fingerprint
+
+/usr/share/keyrings/hashicorp-archive-keyring.gpg
+-------------------------------------------------
+pub   rsa4096 XXXX-XX-XX [SC]
+AAAA AAAA AAAA AAAA
+uid           [ unknown] HashiCorp Security (HashiCorp Package Signing) <security+packaging@hashicorp.com>
+sub   rsa4096 XXXX-XX-XX [E]
+```
+
+### Ajout du repository d'Hashicorp
+```bash
+echo "deb [signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] \
+https://apt.releases.hashicorp.com $(lsb_release -cs) main" | \
+sudo tee /etc/apt/sources.list.d/hashicorp.list
+```
+
+
+### Installation de Terraform 
+```bash
+sudo apt-get update && sudo apt-get install terraform
+```
+
+### Valider l'installation
+Une fois l'installation effectuée, nous vérifions que le binaire Terraform est fonctionnel : 
+```bash
+terraform -help
+Usage: terraform [-version] [-help] <command> [args]
+
+The available commands for execution are listed below.
+The most common, useful commands are shown first, followed by
+less common or more advanced commands. If you're just getting
+started with Terraform, stick with the common commands. For the
+other commands, please read the help and docs before usage.
+```
+
+
+## Initialiser son premier répertoire de travail
+Nous allons créer un dossier et l'initialiser avec le provider de notre étude de cas, [Proxmox](https://registry.terraform.io/providers/Telmate/proxmox/latest/docs) :
+```bash
+mkdir Terraform
+touch provider.tf
+```
+
+Voici le contenu du fichier "provider.tf"
+```hcl
+terraform {
+  required_version = ">=1.0.11"
+
+  required_providers {
+    proxmox = {
+      source = "Telmate/proxmox"
+      version = "=2.9.11"
+    }
+  }
+}
+```
+> Pour des raisons de compatibilité API, je n'utilise pas la dernière version du provider disponible à l'écriture de cet article (2.9.14)
+{.is-info}
+
+Une fois le fichier créé, initialisons le dossier afin qu'il puisse télécharger les composants nécessaires afin de communiquer avec l'API Proxmox :
+
+```bash
+terraform init
++ terraform init
+
+Initializing the backend...
+
+Initializing provider plugins...
+- Finding telmate/proxmox versions matching "2.9.11"...
+- Installing telmate/proxmox v2.9.11...
+- Installed telmate/proxmox v2.9.11 (self-signed, key ID A9EBBE091B35AFCE)
+
+Partner and community providers are signed by their developers.
+If you'd like to know more about provider signing, you can read about it here:
+https://www.terraform.io/docs/cli/plugins/signing.html
+
+Terraform has created a lock file .terraform.lock.hcl to record the provider
+selections it made above. Include this file in your version control repository
+so that Terraform can guarantee to make the same selections by default when
+you run "terraform init" in the future.
+
+Terraform has been successfully initialized!
+
+You may now begin working with Terraform. Try running "terraform plan" to see
+any changes that are required for your infrastructure. All Terraform commands
+should now work.
+
+If you ever set or change modules or backend configuration for Terraform,
+rerun this command to reinitialize your working directory. If you forget, other
+commands will detect it and remind you to do so if necessary.
+```
+
+# Conclusion
+
+Dans cet article, nous avons installé Terraform sur notre OS de travail, créer et initialiser un dossier avec le provider correspondant à notre étude de cas.
+Dans les prochains articles, nous allons rédiger nos fichiers de déploiements de machine afin de pouvoir déployer notre infrastructure.
