Your version of Terraform is out of date! The latest version
is 0.14.7. You can update by downloading from https://www.terraform.io/downloads.html
# terraform
Usage: terraform [global options] <subcommand> [args]
The available commands for execution are listed below.
The primary workflow commands are given first, followed by
less common or more advanced commands.
Main commands:
init Prepare your working directory for other commands
validate Check whether the configuration is valid
plan Show changes required by the current configuration
apply Create or update infrastructure
destroy Destroy previously-created infrastructure
All other commands:
console Try Terraform expressions at an interactive command prompt
fmt Reformat your configuration in the standard style
force-unlock Release a stuck lock on the current workspace
get Install or upgrade remote Terraform modules
graph Generate a Graphviz graph of the steps in an operation
import Associate existing infrastructure with a Terraform resource
login Obtain and save credentials for a remote host
logout Remove locally-stored credentials for a remote host
output Show output values from your root module
providers Show the providers required for this configuration
refresh Update the state to match remote systems
show Show the current state or a saved plan
state Advanced state management
taint Mark a resource instance as not fully functional
untaint Remove the 'tainted' state from a resource instance
version Show the current Terraform version
workspace Workspace management
Global options (use these before the subcommand, if any):
-chdir=DIR Switch to a different working directory before executing the
given subcommand.
-help Show this help output, or the help for a specified subcommand.
-version An alias for the "version" subcommand.

对于一个terraform资源项目，我这里创建了3个基本文件，分别为：main.tf（入口文件），variables.tf（变量信息），versions.tf（版本信息）

Initializing the backend...
Initializing provider plugins...
- Reusing previous version of aliyun/alicloud from the dependency lock file
- Using aliyun/alicloud v1.115.1 from the shared cache directory
Terraform has been successfully initialized!

fmt默认会回格式化处理当前目录下.tf文件，并格式为标准的tf格式。

terraform plan 会检查一组更改的执行计划是否符合您的期望，而不会更改实际资源或状态。

# terraform plan
An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
+ create
Terraform will perform the following actions:

+ resource "alicloud_instance" "wanzi_test" {
+ availability_zone = "cn-hangzhou-i"
+ credit_specification = (known after apply)

terraform apply 会自动生成一个资源创建计划，并批准执行该计划，同时在当前目录下会生成tfstate文件
