执行计划
执行plan 查看会创建什么资源
➜ ec2 git:(master) ✗ terraform plan
An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:

Note: You didn't specify an "-out" parameter to save this plan, so Terraform
can't guarantee that exactly these actions will be performed if
"terraform apply" is subsequently run.

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

根据上面提示，创建的实例为[id=i-04f5cf7097b964650] 查找如下
删除资源
删除资源的时候也会提示二次确认
➜ ec2 git:(master) ✗ terraform destroy
An execution plan has been generated and is shown below.

Do you really want to destroy all resources?
Terraform will destroy all your managed infrastructure, as shown above.
There is no undo. Only 'yes' will be accepted to confirm.
