Import Existing Infrastructure to Terraform

Terraform is an orchestration tool that uses declarative code to build, change, and version infrastructure that is made up of server instances and services. You can use Linode’s official Terraform provider to interact with Linode services. Existing Linode infrastructure can be imported and brought under Terraform management. This guide describes how to import existing Linode infrastructure into Terraform using the official Linode provider plugin.

Note
Terraform’s Linode Provider has been updated and now requires Terraform version 0.12+. To learn how to safely upgrade to Terraform version 0.12+, see Terraform’s official documentation. View Terraform v0.12’s changelog for a full list of new features and version incompatibility notes.

Before You Begin

Terraform and the Linode Terraform provider should be installed in your development environment. You should also have a basic understanding of Terraform resources. To install and learn about Terraform, read our Use Terraform to Provision Linode Environments guide.
To use Terraform you must have a valid API access token. For more information on creating a Linode API access token, visit our Getting Started with the Linode API guide.
This guide uses the Linode CLI to retrieve information about the Linode infrastructure you import to Terraform. For more information on the setup, installation, and usage of the Linode CLI, check out the Using the Linode CLI guide.

Terraform’s Import Command

Throughout this guide the terraform import command is used to import Linode resources. At the time of writing this guide, the import command does not generate a Terraform resource configuration. Instead, it imports your existing resources into Terraform’s state.

State is Terraform’s stored JSON mapping of your current Linode resources to their configurations. You can access and use the information provided by the state to manually create a corresponding resource configuration file and manage your existing Linode infrastructure with Terraform.

Additionally, there is no current way to import more than one resource at a time. All resources must be individually imported.

Caution
When importing your infrastructure to Terraform, failure to accurately provide your Linode service’s ID information can result in the unwanted alteration or destruction of the service. Please follow the instructions provided in this guide carefully. It might be beneficial to use multiple Terraform Workspaces to manage separate testing and production infrastructures.

Import a Linode to Terraform

Retrieve Your Linode’s ID

Using the Linode CLI, retrieve a list of all your Linode instances and find the ID of the Linode you would like to manage under Terraform:
```
linode-cli linodes list --json --pretty
```
```
[
  {
    "id": 11426126,
    "image": "linode/debian9",
    "ipv4": [
    "192.0.2.2"
    ],
    "label": "terraform-import",
    "region": "us-east",
    "status": "running",
    "type": "g6-standard-1"
  }
]
```
This command will return a list of your existing Linodes in JSON format. From the list, find the Linode you would like to import and copy down its corresponding id. In this example, the Linode’s ID is 11426126. You will use your Linode’s ID to import your Linode to Terraform.

Create An Empty Resource Configuration

Ensure you are in your Terraform project directory. Create a Terraform configuration file to manage the Linode instance you import in the next section. Your file can be named anything you like, but it must end in .tf. Add a Linode provider block with your API access token and an empty linode_instance resource configuration block in the file:
Note
The example resource block defines example_label as the label. This can be changed to any value you prefer. This label is used to reference your Linode resource configuration within Terraform. It does not have to be the same label originally assigned to the Linode when it was created outside of Terraform.
File: linode_import.tf
1 2 3 4 5
provider "linode" { token = "your_API_access_token" } resource "linode_instance" "example_label" {}

Import Your Linode to Terraform

Run the import command, supplying the linode_instance resource’s label, and the Linode’s ID that was retrieved in the Retrieve Your Linode’s ID section :

 terraform import linode_instance.example_label linodeID

You should see a similar output:

linode_instance.example_label: Importing from ID "11426126"...
linode_instance.example_label: Import complete!
  Imported linode_instance (ID: 11426126)
linode_instance.example_label: Refreshing state... (ID: 11426126)

Import successful!

The resources that were imported are shown above. These resources are now in
your Terraform state and will henceforth be managed by Terraform.

This command will create a terraform.tfstate file with information about your Linode. You will use this information to fill out your resource configuration.

To view the information created by terraform import, run the show command. This command displays a list of key-value pairs representing information about the imported Linode instance.

Fill In Your Linode’s Configuration Data

As mentioned in the Terraform’s Import Command section, you must manually create your resource configurations when importing existing infrastructure.

Fill in the configuration values for the linode_instance resource block. In the example below, the necessary values were collected from the output of the terraform show command applied in Step 2 of the Import Your Linode to Terraform section. The file’s comments indicate the corresponding keys used to determine the values for the linode_instance configuration block.

        root_device = "/dev/sda"               #config.root_device
        devices {
            sda {
                disk_label = "Debian 9 Disk"    #config.devices.sda.disk_label
            }
            sdb {
                disk_label = "512 MB Swap Image" #config.devices.sdb.disk_label
            }
        }
    }
    disk {
        label = "Debian 9 Disk"      #disk.label (filesystem = "ext4")
        size = "50688"               #disk.size

        size = "512"                 #disk.1.size
    }
}

Note
If your Linode uses more than two disks (for instance, if you have attached a Block Storage Volume), you need to add those disks to your Linode resource configuration block. In order to add a disk, you must add the disk to the devices stanza and create an additional disk stanza.

Note
If you have more than one configuration profile, you must choose which profile to boot from with the boot_config_label key. For example:
resource "linode_instance" "example_label" {
    boot_config_label = "My Debian 9 Disk Profile"
...

To check for errors in your configuration, run the plan command:
```
terraform plan
```
terraform plan shows you the changes that would take place if you were to apply the configurations with a terraform apply. Running terraform plan is a good way to determine if the configuration you provided is exact enough for Terraform to take over the management of your Linode.
Caution
Running terraform plan displays any changes that are applied to your existing infrastructure based on your configuration file(s). However, you will not be notified about the addition and removal of disks with terraform plan. For this reason, it is vital that the values you include in your linode_instance resource configuration block match the values generated from running the terraform show command.
Once you have verified the configurations you provided in the linode_instance resource block, you are ready to begin managing your Linode instance with Terraform. Any changes or updates can be made by:
- updating your linode_instance_import.tf file
- verifying the changes with the terrform plan command
- applying the changes with the terraform apply command
For more available configuration options, visit the Linode Instance Terraform documentation.

Import a Domain to Terraform

Retrieve Your Domain’s ID

Using the Linode CLI, retrieve a list of all your domains to find the ID of the domain you would like to manage under Terraform:
```
 linode-cli domains list --json --pretty
```
You should see output like the following:
```
[
  {
    "domain": "import-example.com",
    "id": 1157521,
    "soa_email": "webmaster@import-example.com",
    "status": "active",
    "type": "master"
  }
]
```
Find the domain you would like to import and copy down the ID. You need this ID to import your domain to Terraform.

Create an Empty Resource Configuration

Ensure you are in your Terraform project directory. Create a Terraform configuration file to manage the domain you import in the next section. Your file can be named anything you like, but must end in .tf. Add a Linode provider block with your API access token and an empty linode_domain resource configuration block to the file:
File: domain_import.tf
1 2 3 4 5
provider "linode" { token = "Your API Token" } resource "linode_domain" "example_label" {}

Import Your Domain to Terraform

Run the import command, supplying the linode_domain resource’s label, and the domain ID that was retrieved in the Retrieve Your Domain’s ID section:

 terraform import linode_domain.example_label domainID

You should see output similar to the following:

linode_domain.example_label: Importing from ID "1157521"...
linode_domain.example_label: Import complete!
  Imported linode_domain (ID: 1157521)
linode_domain.example_label: Refreshing state... (ID: 1157521)

Import successful!

The resources that were imported are shown above. These resources are now in
your Terraform state and will henceforth be managed by Terraform.

Import a Domain Record to Terraform

Retrieve Your Domain’s ID and Your Domain Record’s ID

Due to the way the Linode API accesses domain records, you need to provide both the Domain ID and the Domain Record ID to import a Domain Record.

Using the Linode CLI, retrieve a list of all your domains to find the ID of the domain that includes the record you would like to manage under Terraform:
```
 linode-cli domains list --json --pretty
```
You should see output like the following:
```
[
  {
    "domain": "import-example.com",
    "id": 1157521,
    "soa_email": "webmaster@import-example.com",
    "status": "active",
    "type": "master"
  }
]
```
Find the domain that contains the record you would like to import and copy down the ID. You will need this ID to import your domain record to Terraform.
Using the Linode CLI, retrieve a list of your domain’s records to find the ID of the record you would like to manage under Terraform. Substitute domainID with the ID of your domain:
```
linode-cli domains records-list domainID --json --pretty
```
You should see an output like the following:
```
[
  {
    "id": 12331520,

provider "linode" { token = "1a2b3c..." } resource "linode_volume" "example_label" { label = "import-example" region = "us-east" size = "20" }
Note
Though it is not required, it’s a good idea to include a configuration for the size of the volume. This allows it to be managed more easily should you ever choose to expand the Volume. It is not possible to reduce the size of a volume.
Check for errors in your configuration by running the plan command:
```
 terraform plan
```
terraform plan shows you the changes that would take place if you were to apply the configurations with the terraform apply command. Running terraform plan should result in Terraform displaying that no changes are to be made.
Once you have verified the configurations you provided in the linode_volume block, you are ready to begin managing your Block Storage Volume with Terraform. Any changes or updates can be made by updating your linode_volume_example.tf file, then verifying the changes with the terrform plan command, and then finally applying the changes with the terraform apply command.
For more optional configuration options, visit the Linode Volume Terraform documentation.

Import a NodeBalancer to Terraform

Configuring Linode NodeBalancers with Terraform requires three separate resource configuration blocks: one to create the NodeBalancer, a second for the NodeBalancer Configuration, and a third for the NodeBalancer Nodes.

Retrieve Your NodeBalancer, NodeBalancer Config, NodeBalancer Node IDs

Using the Linode CLI, retrieve a list of all your NodeBalancers to find the ID of the NodeBalancer you would like to manage under Terraform:
```
 linode-cli nodebalancers list --json --pretty
```
You should see output similar to the following:
```
[
  {
    "client_conn_throttle": 0,
    "hostname": "nb-192-0-2-3.newark.nodebalancer.linode.com",
    "id": 40721,
    "ipv4": "192.0.2.3",
    "ipv6": "2600:3c03:1::68ed:945f",
    "label": "terraform-example",
    "region": "us-east"
  }
]
```
Find the NodeBalancer you would like to import and copy down the ID. You will use this ID to import your NodeBalancer to Terraform.

Retrieve your NodeBalancer configuration by supplying the ID of the NodeBalancer you retrieved in the previous step:

 linode-cli nodebalancers configs-list 40721 --json --pretty

You should see output similar to the following:

[
  {
    "algorithm": "roundrobin",
    "check_passive": true,
    "cipher_suite": "recommended",
    "id": 35876,
    "port": 80,
    "protocol": "http",
    "ssl_commonname": "",
    "ssl_fingerprint": "",
    "stickiness": "table"
  }
]

Copy down the ID of your NodeBalancer configuration, you will use it to import your NodeBalancer configuration to Terraform.

Retrieve a list of Nodes corresponding to your NodeBalancer to find the label and address of your NodeBalancer Nodes. Supply the ID of your NodeBalancer as the first argument and the ID of your NodeBalancer configuration as the second:
```
 linode-cli nodebalancers nodes-list 40721 35876 --json --pretty
```
You should see output like the following:
```
[
  {
    "address": "192.168.214.37:80",
    "id": 327539,
    "label": "terraform-import",
    "mode": "accept",
    "status": "UP",
    "weight": 100
  }
]
```
If you are importing a NodeBalancer, chances are your output lists more than one Node. Copy down the IDs of each Node. You will use them to import your Nodes to Terraform.

Create Empty Resource Configurations

Ensure you are in your Terraform project directory. Create a Terraform configuration file to manage the NodeBalancer you import in the next section. Your file can be named anything you like, but must end in .tf.

Add a Linode provider block with your API access token and empty linode_nodebalancer, linode_nodebalancer_config, and linode_nodebalancer_node resource configuration blocks to the file. Be sure to give the resources appropriate labels. These labels are used to reference the resources locally within Terraform:

File: linode_nodebalancer_example.tf

4
5

provider "linode" {
    token = "Your API Token"
}

resource "linode_nodebalancer" "example_nodebalancer_label" {}

resource "linode_nodebalancer_config" "example_nodebalancer_config_label" {}

resource "linode_nodebalancer_node" "example_nodebalancer_node_label" {}

If you have more than one NodeBalancer Configuration, you will need to supply multiple linode_nodebalancer_config resource blocks with different labels. The same is true for each NodeBalancer Node requiring an additional linode_nodebalancer_node block.

Import Your NodeBalancer, NodeBalancer Configuration, and NodeBalancer Nodes to Terraform

Run the import command for your NodeBalancer, supplying your local label and the ID of your NodeBalancer as the last parameter.

terraform import linode_nodebalancer.example_nodebalancer_label nodebalancerID

You should see output similar to the following:

linode_nodebalancer.example_nodebalancer_label: Importing from ID "40721"...
linode_nodebalancer.example_nodebalancer_label: Import complete!
  Imported linode_nodebalancer (ID: 40721)
linode_nodebalancer.example_nodebalancer_label: Refreshing state... (ID: 40721)

Import successful!

The resources that were imported are shown above. These resources are now in
your Terraform state and will henceforth be managed by Terraform.

Run the import command for your NodeBalancer configuration, supplying your local label, and the ID of your NodeBalancer and the ID of your NodeBalancer configuration separated by commas as the last argument.

terraform import linode_nodebalancer_config.example_nodebalancer_config_label nodebalancerID,nodebalancerconfigID

You should see output similar to the following:

linode_nodebalancer_config.example_nodebalancer_config_label: Importing from ID "40721,35876"...
linode_nodebalancer_config.example_nodebalancer_config_label: Import complete!
  Imported linode_nodebalancer_config (ID: 35876)
linode_nodebalancer_config.example_nodebalancer_config_label: Refreshing state... (ID: 35876)

Import successful!

The resources that were imported are shown above. These resources are now in
your Terraform state and will henceforth be managed by Terraform.

Run the import command for you NodeBalancer Nodes, supplying your local label, and the ID of your NodeBalancer, the ID of your NodeBalancer Configuration, and your NodeBalancer Node, separated by commas, as the last argument.

terraform import linode_nodebalancer_node.example_nodebalancer_node_label nodebalancerID,nodebalancerconfigID,nodebalancernodeID

You should see output like the following:

linode_nodebalancer_node.example_nodebalancer_node_label: Importing from ID "40721,35876,327539"...
linode_nodebalancer_node.example_nodebalancer_node_label: Import complete!
  Imported linode_nodebalancer_node (ID: 327539)
linode_nodebalancer_node.example_nodebalancer_node_label: Refreshing state... (ID: 327539)

Import successful!

The resources that were imported are shown above. These resources are now in
your Terraform state and will henceforth be managed by Terraform.

Running terraform import creates a terraform.tfstate file with information about your NodeBalancer. You use this information to fill out your resource configuration. To view the information created by terraform import, run the show command:

terraform show

You should see output like the following:

# linode_nodebalancer.example_nodebalancer_label:

}

Fill In Your NodeBalancer’s Configuration Data

As mentioned in the Terraform’s Import Command section, you must manually create your resource configurations when importing existing infrastructure.

Fill in the configuration values for all three NodeBalancer resource configuration blocks. The necessary values for the example resource configuration file were collected from the output of the terraform show command applied in Step 4 of the Import Your NodeBalancer, NodeBalancer Configuration, and NodeBalancer Nodes to Terraform section:

File: linode_nodebalancer_example.tf

provider "linode" {
    token = "1a2b3c..."
}

resource "linode_nodebalancer" "nodebalancer_import" {
    label = "terraform-example"
    region = "us-east"
}

resource "linode_nodebalancer_config" "nodebalancer_config_import" {
    nodebalancer_id = "40721"
}

resource "linode_nodebalancer_node" "nodebalancer_node_import" {
    label = "terraform-import"
    address = "192.168.214.37:80"
    nodebalancer_id = "40721"
    config_id = "35876"
}
    

Check for errors in your configuration by running the plan command:
```
 terraform plan
```
terraform plan shows you the changes that would take place if you were to apply the configurations with the terraform apply command. Running terraform plan should result in Terraform displaying that no changes are to be made.
Once you have verified the configurations you provided in all three NodeBalancer configuration blocks, you are ready to begin managing your NodeBalancers with Terraform. Any changes or updates can be made by updating your linode_nodebalancer_example.tf file, then verifying the changes with the terrform plan command, and finally, applying the changes with the terraform apply command.
For more available configuration options, visit the Linode NodeBalancer, Linode NodeBalancer Config, and Linode NodeBalancer Node Terraform documentation.
