使用 Terraform 部署 ParallelCluster API

在本教程中，您将定义一个简单的 Terraform 项目来部署 API。 ParallelCluster

先决条件

Terraform v1.5.7+ 已安装。
具有部署 ParallelCluster API 权限的 IAM 角色。请参阅所需的权限。

定义一个 Terraform 项目

创建一个名为的目录my-pcluster-api。

您创建的所有文件都将位于此目录中。

创建用于配置provider.tf AWS 提供程序的文件。


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

使用 ParallelCluster模块创建文件main.tf以定义资源。


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"
  }
}

创建文件variables.tf以定义可以为此项目注入的变量。


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."
}

创建文件terraform.tfvars以设置变量的任意值。

下面的文件us-east-1使用堆栈名称部署了 ParallelCluster API 3.10.0。MyParallelClusterAPI-310您将能够使用其堆栈名称来引用此 ParallelCluster API 部署。
```
region = "us-east-1"
api_stack_name = "MyParallelClusterAPI-310"
api_version = "3.10.0"
```

创建文件outputs.tf以定义此项目返回的输出。


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

项目目录是：


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

要部署 API，请按顺序运行标准的 Terraform 命令。

构建项目：
```
terraform init
```
定义部署计划：
```
terraform plan -out tfplan
```
部署计划：
```
terraform apply tfplan
```

所需的权限

你需要以下权限才能使用 Terraform 部署 ParallelCluster API：
