Importing Azure resources to terraform

1. Install Terraform on mac

brew install terraform

2. Install the azure-cli

brew install azure-cli


3. Install terraformer tool
 
To import the existing resources from (AWS, Google cloud,AZURE)

brew install terraformer

4. Authenticate with azure 


az login

[
  {
    "cloudName": "AzureCloud",
    "homeTenantId": "58fb75e6-9db3-4492-b319-a095a08786ce",
    "id": "bc8ba97c-c476-4996-9d49-c92ccfe258f2",
    "isDefault": true,
    "managedByTenants": [],
    "name": "Free Trial",
    "state": "Enabled",
    "tenantId": "58fb75e6-9db3-4492-b319-a095a08786ce",
    "user": {
      "name": "kiranchavala@gmail.com",
      "type": "user"
    }
  }
]


5. Create a provider.tf file with the following content

mkdir -p test

cd test


vi  provider.tf

provider "azurerm" {
  features {}
}


terraform init

export ARM_SUBSCRIPTION_ID=bc8ba97c-c476-4996-9d49-c92ccfe258f2



6. To import all the existing resources from your Azure account

Here "test_gourp" is the resource group in ur Azure account

terraformer import azure -R test_group  -r "*"

specific resource

terraformer import azure -R test_group -r virtual_machine


7. This will generate Terraform files for the existing resources (instance)


├── generated
│   └── azurerm
│       └── virtual_machine
│           ├── linux_virtual_machine.tf
│           ├── outputs.tf
│           ├── provider.tf
│           └── terraform.tfstate
└── provider.tf


8. Now we can control the exisitng resources

cd generated/azurerm/virtual_machine/

terraform state replace-provider -auto-approve "registry.terraform.io/-/azurerm" "hashicorp/azurerm"



terraform init
 
terraform refresh


 
9. To change the setting of a resource after editing the respective resource tf file
 
terraform plan
 
terraform apply
