Terraform学习日记-AWS-EC2_terraform --install-autocomplete

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

2

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

应用你配置文件

会让你输入yes ，确认创建动作

# terraform apply

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

  # aws_instance.app_server will be created
  + resource "aws_instance" "app_server" {

Plan: 1 to add, 0 to change, 0 to destroy.

Do you want to perform these actions?
  Terraform will perform the actions described above.
  Only 'yes' will be accepted to approve.
### 这里输入yes
  Enter a value: yes

aws_instance.app_server: Creating...
aws_instance.app_server: Still creating... [10s elapsed]
aws_instance.app_server: Creation complete after 15s [id=i-00d64aa676c0562fa]

Apply complete! Resources: 1 added, 0 changed, 0 destroyed.
