Command: import

The opentf import command imports existing resources into OpenTF.

Usage​

Usage: opentf import [options] ADDRESS ID

Import will find the existing resource from ID and import it into your OpenTF state at the given ADDRESS.

ADDRESS must be a valid resource address. Because any resource address is valid, the import command can import resources into modules as well as directly into the root of your state.

ID is dependent on the resource type being imported. For example, for AWS EC2 instances it is the instance ID (i-abcd1234) but for AWS Route53 zones it is the zone ID (Z12ABC4UGMOZ2N). Please reference the provider documentation for details on the ID format. If you're unsure, feel free to just try an ID. If the ID is invalid, you'll just receive an error message.

~> Warning: OpenTF expects that each remote object it is managing will be bound to only one resource address, which is normally guaranteed by OpenTF itself having created all objects. If you import existing objects into OpenTF, be careful to import each remote object to only one OpenTF resource address. If you import the same object multiple times, OpenTF may exhibit unwanted behavior. For more information on this assumption, see the State section.

The command-line flags are all optional. The following flags are available:

  • -config=path - Path to directory of OpenTF configuration files that configure the provider for import. This defaults to your working directory. If this directory contains no OpenTF configuration files, the provider must be configured via manual input or environmental variables.

  • -input=true - Whether to ask for input for provider configuration.

  • -lock=false - Don't hold a state lock during the operation. This is dangerous if others might concurrently run commands against the same workspace.

  • -lock-timeout=0s - Duration to retry a state lock.

  • -no-color - If specified, output won't contain any color.

  • -parallelism=n - Limit the number of concurrent operation as OpenTF walks the graph. Defaults to 10.

  • -provider=provider - Deprecated Override the provider configuration to use when importing the object. By default, OpenTF uses the provider specified in the configuration for the target resource, and that is the best behavior in most cases.

  • -var 'foo=bar' - Set a variable in the OpenTF configuration. This flag can be set multiple times. Variable values are interpreted as literal expressions in the OpenTF language, so list and map values can be specified via this flag.

  • -var-file=foo - Set variables in the OpenTF configuration from a variable file. If a terraform.tfvars or any .auto.tfvars files are present in the current directory, they will be automatically loaded. terraform.tfvars is loaded first and the .auto.tfvars files after in alphabetical order. Any files specified by -var-file override any values set automatically from files in the working directory. This flag can be used multiple times. This is only useful with the -config flag.

For configurations using the cloud backend or the remote backend only, opentf import also accepts the option -ignore-remote-version.

For configurations using the local backend only, opentf import also accepts the legacy options -state, -state-out, and -backup.

Provider Configuration​

OpenTF will attempt to load configuration files that configure the provider being used for import. If no configuration files are present or no configuration for that specific provider is present, OpenTF will prompt you for access credentials. You may also specify environmental variables to configure the provider.

The only limitation OpenTF has when reading the configuration files is that the import provider configurations must not depend on non-variable inputs. For example, a provider configuration cannot depend on a data source.

As a working example, if you're importing AWS resources and you have a configuration file with the contents below, then OpenTF will configure the AWS provider with this file.

variable "access_key" {}
variable "secret_key" {}

provider "aws" {
  access_key = "${var.access_key}"
  secret_key = "${var.secret_key}"
}

Example: Import into Resource​

This example will import an AWS instance into the aws_instance resource named foo:

$ opentf import aws_instance.foo i-abcd1234

Example: Import into Module​

The example below will import an AWS instance into the aws_instance resource named bar into a module named foo:

$ opentf import module.foo.aws_instance.bar i-abcd1234

Example: Import into Resource configured with count​

The example below will import an AWS instance into the first instance of the aws_instance resource named baz configured with count:

$ opentf import 'aws_instance.baz[0]' i-abcd1234

Example: Import into Resource configured with for_each​

The example below will import an AWS instance into the "example" instance of the aws_instance resource named baz configured with for_each:

Linux, Mac OS, and UNIX:

$ opentf import 'aws_instance.baz["example"]' i-abcd1234

PowerShell:

$ opentf import 'aws_instance.baz[\"example\"]' i-abcd1234

Windows cmd.exe:

$ opentf import aws_instance.baz[\"example\"] i-abcd1234
