Création d'un container Linux Avec Terraform

Paramétrage de PROXMOX (création d'une clé d'API)

Attention Il faut bien noté le token !!
Installation de TERRAFORM sur une DEBIAN (Créer un container de management)
1. Suivre la documentation officielle https://developer.hashicorp.com/terraform/tutorials/aws-get-started/install-cli
2. Vérifier l'installation de TERRAFORM:
```
root@MGT-FRONT-01:~# terraform -v
Terraform v1.5.2
on linux_amd64
```

Premier déploiement de machine

Créer un dossier de travail:
```
mkdir VM_CREATION && cd VM_CREATION
```

On va créer un fichier provider.tf ce fichier va référencer les module que nous utiliserons pour la création des VM.

# Creation du fichier provider.tf
nano provider.tf

Contenu du fichier:

terraform {
  required_providers {
    proxmox = {
      source = "telmate/proxmox"
#      version = "2.7.4"
    }
  }
}
provider "proxmox" {
  # url de Proxmox
  pm_api_url = "https://192.168.1.179:8006/api2/json"
  # api token id is in the form of: <username>@pam!<tokenId>
  pm_tls_insecure = true
  pm_parallel = 2
  pm_user="root@pam"
  pm_password="Espoir15"
}

On créer le fichier web.tf:

nano web.tf

Contenu du fichier:

resource "proxmox_lxc" "web" {
  count        = 2
  target_node  = "pve-front-01"
  hostname     = "web-front-0${count.index + 1}"
  start        = true

  unprivileged = true
  ostype       = "debian"
  nameserver   = "172.16.0.3 172.16.0.4 1.1.1.1"
  onboot       = true
  searchdomain = "megaproduction.local"
  memory       = "512"
#  pool         = "BTS2"
  cores        = "1"

  EOT
   
  // Terraform will crash without rootfs defined
  rootfs {
    storage = "VMs_HDD"
    size    = "8G"
  }

  features {
    fuse    = true

    mount   = "nfs;cifs"
  }

  network {
    name   = "eth0"
    bridge = "vmbr2"
    ip     = "10.10.10.${2 + count.index + 1}/26"
    gw     = "10.10.10.1"
  }
}

source du provider terraform PROVIDER-TERRAFORM

Initialisation du dossier:

root@MGT-FRONT-01:~# terraform init 

Initializing the backend...

Initializing provider plugins...
- Finding latest version of telmate/proxmox...
- Installing telmate/proxmox v2.9.14...
- Installed telmate/proxmox v2.9.14 (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.

Planification du déploiement (Montre ce qui va être déployé):
