Installer et configurer Terraform

Cette page décrit la procédure à suivre pour installer et configurer Terraform pour Google Cloud dans Cloud Shell et dans un shell local. Cloud Shell est un environnement de shell interactif pour Google Cloud qui vous permet de vous familiariser avec Google Cloud, et de gérer vos projets et vos ressources depuis un navigateur Web.

Cloud Shell

Pour utiliser un terminal en ligne avec la gcloud CLI et Terraform déjà configurés, activez Cloud Shell :

En bas de la page, une session Cloud Shell démarre et affiche une invite de ligne de commande. L'initialisation de la session peut prendre quelques secondes.
Create or select a Google Cloud project.

Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.
- Create a Google Cloud project:
```
gcloud projects create PROJECT_ID
```
  Replace PROJECT_ID with a name for the Google Cloud project you are creating.
- Select the Google Cloud project that you created:
```
gcloud config set project PROJECT_ID
```
  Replace PROJECT_ID with your Google Cloud project name.
Make sure that billing is enabled for your Google Cloud project.
Pour provisionner des ressources Google Cloud à l'aide de Terraform, vous devez activer les API correspondantes :
```
gcloud services enable "API"
```
Remplacez API par l'API que vous souhaitez activer.
Pour provisionner des ressources Google Cloud à l'aide de Terraform, vous avez besoin de rôles Identity and Access Management spécifiques à ces ressources.
1. Sur la page de documentation des rôles IAM, déterminez le ou les rôles requis.
2. Grant roles to your user account. Run the following command once for each of the following IAM roles:
```
gcloud projects add-iam-policy-binding PROJECT_ID --member="USER_IDENTIFIER" --role=ROLE
```
  - Replace PROJECT_ID with your project ID.
  - Replace USER_IDENTIFIER with the identifier for your user account. For example, user:myemail@example.com.
  - Replace ROLE with each individual role.

Exécutez la commande suivante pour vérifier que Terraform est disponible :
