* command/import: properly use `-provider` supplied on the command line The import command now attaches the provider configuration in the resource instance, if set. That config is attached to the NodeAbstractResource during the import graph building. This prevents errors when the implied provider is not actually in the configuration at all, which may happen when a configuration is using the `-beta` version of a provider (and only that `-beta` version). * command/import: fix variable reassignment and update docs Fixes #22564

# Command: import
|
|
|
|
The `terraform import` command is used to
|
|
[import existing resources](/docs/import/index.html)
|
|
into Terraform.
|
|
|
|
## Usage
|
|
|
|
Usage: `terraform import [options] ADDRESS ID`
|
|
|
|
Import will find the existing resource from ID and import it into your Terraform
|
|
state at the given ADDRESS.
|
|
|
|
ADDRESS must be a valid [resource address](/docs/internals/resource-addressing.html).
|
|
Because any resource address is valid, the import command can import resources
|
|
into modules as well directly into the root of your state.
|
|
|
|
ID is dependent on the resource type being imported. For example, for AWS
|
|
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.
|
|
|
|
The command-line flags are all optional. The list of available flags are:
|
|
|
|
* `-backup=path` - Path to backup the existing state file. Defaults to
|
|
the `-state-out` path with the ".backup" extension. Set to "-" to disable
|
|
backups.
|
|
|
|
* `-config=path` - Path to directory of Terraform configuration files that
|
|
configure the provider for import. This defaults to your working directory.
|
|
If this directory contains no Terraform configuration files, the provider
|
|
must be configured via manual input or environmental variables.
|
|
|
|
* `-input=true` - Whether to ask for input for provider configuration.
|
|
|
|
* `-lock=true` - Lock the state file when locking is supported.
|
|
|
|
* `-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 Terraform
|
|
[walks the graph](/docs/internals/graph.html#walking-the-graph). Defaults
|
|
to 10.
|
|
|
|
* `-provider=provider` - **Deprecated** Override the provider configuration to
|
|
use when importing the object. By default, Terraform uses the provider specified
|
|
in the configuration for the target resource, and that is the best behavior in most cases.
|
|
|
|
* `-state=path` - Path to the source state file to read from. Defaults to the
|
|
configured backend, or "terraform.tfstate".
|
|
|
|
* `-state-out=path` - Path to the destination state file to write to. If this
|
|
isn't specified the source state file will be used. This can be a new or
|
|
existing path.
|
|
|
|
* `-var 'foo=bar'` - Set a variable in the Terraform configuration. This flag
|
|
can be set multiple times. Variable values are interpreted as
|
|
[HCL](/docs/configuration/syntax.html#HCL), so list and map values can be
|
|
specified via this flag. This is only useful with the `-config` flag.
|
|
|
|
* `-var-file=foo` - Set variables in the Terraform configuration from
|
|
a [variable file](/docs/configuration/variables.html#variable-files). 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.
|
|
|
|
## Provider Configuration
|
|
|
|
Terraform 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, Terraform will
|
|
prompt you for access credentials. You may also specify environmental variables
|
|
to configure the provider.
|
|
|
|
The only limitation Terraform 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 Terraform will configure
|
|
the AWS provider with this file.
|
|
|
|
```hcl
|
|
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`:
|
|
|
|
```shell
|
|
$ terraform 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`:
|
|
|
|
```shell
|
|
$ terraform 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`](/docs/configuration/resources.html#count-multiple-resource-instances-by-count):
|
|
|
|
```shell
|
|
$ terraform 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`](/docs/configuration/resources.html#for_each-multiple-resource-instances-defined-by-a-map-or-set-of-strings):
|
|
|
|
Linux, Mac OS, and UNIX:
|
|
|
|
```shell
|
|
$ terraform import 'aws_instance.baz["example"]' i-abcd1234
|
|
```
|
|
|
|
PowerShell:
|
|
|
|
```shell
|
|
$ terraform import 'aws_instance.baz[\"example\"]' i-abcd1234
|
|
```
|
|
|
|
Windows `cmd.exe`:
|
|
|
|
```shell
|
|
$ terraform import aws_instance.baz[\"example\"] i-abcd1234
|
|
```
