Salut!
Aujourd’hui nous allons voir ensemble comment nous pouvons automatiser le déploiement de notre cluster AKS avec Terraform.
Je vous invite à lire l’article que j’avais pu écrire il y a quelques mois : Automatiser votre infrastructure Azure avec Terraform.

maxime@Azure:~/aks-terrform$ terraform init Initializing provider plugins... The following providers do not have any version constraints in configuration, so the latest version was installed. To prevent automatic upgrades to new major versions that may contain breaking changes, it is recommended to add version = "..." constraints to the corresponding provider blocks in configuration, with the constraint strings suggested below. * provider.azurerm: version = "~> 1.1" 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.
