# 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. |
