使用地形部署 ParallelCluster API

在本教程中，您將定義一個簡單的 Terraform 項目來部署 API。 ParallelCluster

先決條件

已安裝地形 v1.5.7 +。
具有部署 ParallelCluster API 權限的 IAM 角色。請參閱所需的許可。

定義地形專案

創建一個名為的目錄my-pcluster-api。

您建立的所有檔案都會位於此目錄中。

建立檔案provider.tf以設定提 AWS 供者。


provider "aws" {
  region  = var.region
  profile = var.profile
}

使用 ParallelCluster模組建立檔案main.tf以定義資源。


module "parallelcluster_pcluster_api" {
  source = "aws-tf/parallelcluster/aws//modules/pcluster_api"
  version = "1.0.0"

  region                = var.region
  api_stack_name        = var.api_stack_name
  api_version           = var.api_version
  deploy_pcluster_api   = true
  parameters = {
    EnableIamAdminAccess = "true"
  }
}

創建文件variables.tf以定義可以為此項目注入的變量。


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."
}

建立檔案terraform.tfvars以設定變數的任意值。

下面的文件us-east-1使用堆棧名稱部署了一個 ParallelCluster API 3.10.0。MyParallelClusterAPI-310您將能夠使用其堆棧名稱引用此 ParallelCluster API 部署。
```
region = "us-east-1"
api_stack_name = "MyParallelClusterAPI-310"
api_version = "3.10.0"
```

建立檔案outputs.tf以定義此專案傳回的輸出。


output "pcluster_api_stack_outputs" {
  value = module.parallelcluster_pcluster_api.stack_outputs
}

項目目錄是：


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.

部署 API

若要部署 API，請依序執行標準的地形命令。

建立專案：
```
terraform init
```
定義部署計劃：
```
terraform plan -out tfplan
```
部署計劃：
```
terraform apply tfplan
```

所需的許可

您需要以下權限才能使用 Terraform 部署 ParallelCluster API：
