# Terapkan ParallelCluster API dengan Terraform
Dalam tutorial ini, Anda akan mendefinisikan proyek Terraform sederhana untuk menerapkan API. ParallelCluster
**Prasyarat**
+ Terraform v1.5.7\$1 diinstal.
+ Peran IAM dengan izin untuk menerapkan API. ParallelCluster Lihat [Izin yang diperlukan](tutorial-deploy-terraform-permissions.md).
# Tentukan proyek Terraform
Dalam tutorial ini, Anda akan mendefinisikan proyek Terraform.
1. Buat direktori yang disebut`my-pcluster-api`.
Semua file yang Anda buat akan berada di dalam direktori ini.
1. Buat file `provider.tf` untuk mengkonfigurasi AWS penyedia.
```
provider "aws" {
region = var.region
profile = var.profile
}
```
1. Buat file `main.tf` untuk menentukan sumber daya menggunakan ParallelCluster modul.
```
module "parallelcluster_pcluster_api" {
source = "aws-tf/parallelcluster/aws//modules/pcluster_api"
version = "1.1.0"
region = var.region
api_stack_name = var.api_stack_name
api_version = var.api_version
parameters = {
EnableIamAdminAccess = "true"
}
}
```
1. Buat file `variables.tf` untuk menentukan variabel yang dapat disuntikkan untuk proyek ini.
```
variable "region" {
description = "The region the ParallelCluster API is deployed in."
type = string
default = "us-east-1"
}
variable "profile" {
type = string
description = "The AWS profile used to deploy the clusters."
default = null
}
variable "api_stack_name" {
type = string
description = "The name of the CloudFormation stack used to deploy the ParallelCluster API."
default = "ParallelCluster"
}
variable "api_version" {
type = string
description = "The version of the ParallelCluster API."
}
```
1. Buat file `terraform.tfvars` untuk menetapkan nilai arbitrer untuk variabel.
File di bawah ini menerapkan ParallelCluster API 3.11.1 dalam `us-east-1` menggunakan nama tumpukan. `MyParallelClusterAPI-3111` Anda akan dapat mereferensikan penerapan ParallelCluster API ini menggunakan nama tumpukannya.
**catatan**
`api_version`Penugasan dalam kode berikut dapat diganti dengan AWS ParallelCluster versi yang didukung.
```
region = "us-east-1"
api_stack_name = "MyParallelClusterAPI-3111"
api_version = "3.11.1"
```
1. Buat file `outputs.tf` untuk menentukan output yang dikembalikan oleh proyek ini.
```
output "pcluster_api_stack_outputs" {
value = module.parallelcluster_pcluster_api.stack_outputs
}
```
Direktori proyek adalah:
```
my-pcluster-api
├── main.tf - Terraform entrypoint to define the resources using the ParallelCluster module.
├── outputs.tf - Defines the outputs returned by Terraform.
├── providers.tf - Configures the AWS provider.
├── terraform.tfvars - Set the arbitrary values for the variables, i.e. region, PCAPI version, PCAPI stack name
└── variables.tf - Defines the variables, e.g. region, PCAPI version, PCAPI stack name.
```
# Terapkan API
Untuk menerapkan API, jalankan perintah Terraform standar secara berurutan.
1. Membangun proyek:
```
terraform init
```
1. Tentukan rencana penyebaran:
```
terraform plan -out tfplan
```
1. Menyebarkan rencana:
```
terraform apply tfplan
```
# Izin yang diperlukan
Anda memerlukan izin berikut untuk menerapkan ParallelCluster API dengan Terraform:
