terraform install
https://developer.hashicorp.com/terraform/tutorials/aws-get-started/install-cli
这里我们使用 aws-linux-2022 作为执行环境
# sudo yum install -y yum-utils# sudo yum-config-manager --add-repo https://rpm.releases.hashicorp.com/AmazonLinux/hashicorp.repo# sudo yum -y install terraform
## 验证安装
# terraform -help## 配置自动补全
# touch ~/.bashrc
# terraform -install-autocomplete
配置aws aksk 认证，保证有相关权限创建资源
1.aws configure方式
# aws configure
2.配置aksk env方式
# export AWS_ACCESS_KEY_ID=
# export AWS_SECRET_ACCESS_KEY=
开始练习测试
## 每个项目必须有自己工作目录
# mkdir tfm-ec2
# cd tfm-ec2
# touch main.tf
粘贴我们ec2示例文件，酌情修改
terraform {required_providers {aws = {source = "hashicorp/aws"version = "~> 4.16"}}required_version = ">= 1.2.0"
}provider "aws" {region = "us-west-2"
}resource "aws_instance" "app_server" {ami = "ami-830c94e3"instance_type = "t2.micro"tags = {Name = "ExampleAppServerInstance"}
}
初始化工作环境
##此过程会安装所需的组件，每次新的工作时，需要执行
# terraform init
格式化您的配置
Terraform 将打印出其修改的文件的名称（如果有）。在这种情况下，您的配置文件已正确格式化，因此 Terraform 将不会返回任何文件名
可以测试下，添加多余的空格，这行命令会帮你格式化
# terraform fmt
main.tf
检测的你配置文件
这里我故意加一个字母测试
# terraform validate
╷
│ Error: Unsupported block type
│
│ on main.tf line 16:
│ 16: aresource "aws_instance" "app_server" {
│
│ Blocks of type "aresource" are not expected here. Did you mean "resource"?
修改后效果
# terraform validate
Success! The configuration is valid.[root@ip-172-31-19-57 tfm-ec2]# terraform show
# aws_instance.app_server:应用你配置文件
会让你输入yes ，确认创建动作
