# Import Usage
|
|
|
|
The `terraform import` command is used to import existing infrastructure.
|
|
|
|
The command currently can only import one resource at a time. This means
|
|
you can't yet point Terraform import to an entire collection of resources
|
|
such as an AWS VPC and import all of it. A future version of Terraform will
|
|
be able to do this.
|
|
|
|
Using `terraform import` is simple. An example is shown below:
|
|
|
|
```
|
|
$ terraform import aws_instance.bar i-abcd1234
|
|
...
|
|
```
|
|
|
|
~> **Note:** In order to import resources, the provider should be configured with environment variables.
|
|
We currently do not support passing credentials directly to the provider.
|
|
|
|
The above command imports an AWS instance with the given ID to the
|
|
address `aws_instance.bar`. You can also import resources into modules.
|
|
See the [resource addressing](/docs/internals/resource-addressing.html)
|
|
page for more details on the full range of addresses supported.
|
|
|
|
The ID given is dependent on the resource type being imported. For example,
|
|
AWS instances use their direct IDs. However, AWS Route53 zones use the
|
|
domain name itself. Reference the resource documentation for details on
|
|
what the ID it expects is.
|
|
|
|
As a result of the above command, the resource is put into the state file.
|
|
If you run `terraform plan`, you should see Terraform plan your resource
|
|
for destruction. You now have to create a matching configuration so that
|
|
Terraform doesn't plan a destroy.
|
|
|
|
## Complex Imports
|
|
|
|
The above import is considered a "simple import": one resource is imported
|
|
into the state file. An import may also result in a "complex import" where
|
|
multiple resources are imported. For example, an AWS security group imports
|
|
an `aws_security_group` but also one `aws_security_group_rule` for each rule.
|
|
|
|
In this case, the name of the resource is shown as part of the import output.
|
|
You'll have to create a configuration for each resource imported. If you want
|
|
to rename the other imported resources, the
|
|
[state management commands](/docs/commands/state/index.html) should be used
|
|
to rename resources.
