查看一下目录结构，Terraform会打包好插件为zip文件：
$ tree -a /Users/larry/Software/terraform/plugins
/Users/larry/Software/terraform/plugins-localdisk
└── registry.terraform.io
└── hashicorp
├── local
│ ├── 2.1.0.json
│ ├── index.json
│ └── terraform-provider-local_2.1.0_darwin_amd64.zip
└── random
├── 3.1.0.json
├── index.json
└── terraform-provider-random_3.1.0_darwin_amd64.zip
下次我们可以指定插件目录实现复用：
$ terraform init -plugin-dir=/Users/larry/Software/terraform/plugins
Initializing the backend...
Initializing provider plugins...
- Reusing previous version of hashicorp/random from the dependency lock file
- Reusing previous version of hashicorp/local from the dependency lock file
- Using previously-installed hashicorp/random v3.1.0
- Using previously-installed hashicorp/local v2.1.0
看日志可以看到，Terraform不再下载，而是重用插件。
执行完命令init后，再查看terraform version，则会显示插件的版本：
$ terraform version
Terraform v1.0.11
on darwin_amd64
+ provider registry.terraform.io/hashicorp/local v2.1.0
+ provider registry.terraform.io/hashicorp/random v3.1.0
Terraform对于这种插件目录重用的支持，不只是zip包，二进制也是支持的，但对应的目录结果有点不一样。这里不展开介绍了。
