使环境变量生效source /etc/profile

编译terraformer

  • Run git clone && cd terraformer/

  • Run git clone && cd terraformer/

  • Run go mod download (下载模块到本地缓存，缓存路径是 $GOPATH/pkg/mod/cache)

  • Run go build -v for all providers OR build with one provider: go run build/main.go {google,aws,azure,kubernetes and etc}

  • .Run terraform init against a versions.tf file to install the plugins required for your platform. For example, if you need plugins for the google provider, versions.tf should contain:

    terraform {
    	required_providers {
    		google = {
    			source = "hashicorp/google"
    		}
    	}
    	required_version = ">= 0.13"
    }
    # if need aws
    terraform {
    	required_providers {
    		aws = {
    			source = "hashicorp/aws"
    		}
    	}
    }

  • Or alternatively Copy your Terraform provider’s plugin(s) to

    folder ~/.terraform.d/plugins/{darwin,linux}_amd64/, as appropriate.

    cp terraform-provider-aws_v3.57.0_x5 /root/.terraform.d/plugins/linux_amd64/

$ wget https://releases.hashicorp.com/terraform/1.0.5/terraform_1.0.5_linux_amd64.zip
$ unzip terraform_1.0.5_linux_amd64.zip
$ sudo cp terraform /usr/local/bin/
$ which terraform
/usr/local/bin/terraform
$ terraform init

默认会下载aws插件到当前隐藏目录 ./terraform/.terraform/providers/registry.terraform.io/hashicorp/aws/3.57.0/linux_amd64/terraformprovider-aws_v3.57.0_x5

国内下载不了插件，可以去github下载release进行go编译;或者翻墙下载 https://registry.terraform.io/providers/hashicorp/aws/latest

2021/09/03 10:26:14 aws done importing s3
2021/09/03 10:26:14 Number of resources for service s3: 3

文件会保存在当前的generated目录下

第二种安装方式

除了通过源码进行安装，还有一种比较简单的安装方式是下载对应的terraformer二进制安装包，地址如下：

https://github.com/GoogleCloudPlatform/terraformer/releases

找到对应云厂商的terraformer二进制包即可。这里选择AWS。terraformer-aws-linux-amd64

如果是windows，则选择对应的terraformer-aws-windows-amd64.exe

[root@localhost demoterraform]# wget https://github.com/GoogleCloudPlatform/terraformer/releases/download/0.8.19/terraformer-aws-linux-amd64
[root@localhost demoterraform]# mv terraformer-aws-linux-amd64 terraform-aws
[root@localhost demoterraform]# chmod +x terraform-aws
[root@localhost demoterraform]# alias terraform-aws="$(pwd)/terraform-aws"

输入terraform-aws查看命令有无生效.
