Terraform is able to import existing infrastructure. This allows you take
|
|
resources you've created by some other means and bring it under Terraform
|
|
management.
|
|
|
|
This is a great way to slowly transition infrastructure to Terraform, or
|
|
to be able to be confident that you can use Terraform in the future if it
|
|
potentially doesn't support every feature you need today.
|
|
|
|
~> Warning: Terraform expects that each remote object it is managing will be
|
|
bound to only one resource address, which is normally guaranteed by Terraform
|
|
itself having created all objects. If you import existing objects into Terraform,
|
|
be careful to import each remote object to only one Terraform resource address.
|
|
If you import the same object multiple times, Terraform may exhibit unwanted
|
|
behavior. For more information on this assumption, see
|
|
[the State section](/docs/state/).
|
|
|
|
## Currently State Only
|
|
|
|
The current implementation of Terraform import can only import resources
|
|
into the [state](/docs/state). It does not generate configuration. A future
|
|
version of Terraform will also generate configuration.
|
|
|
|
Because of this, prior to running `terraform import` it is necessary to write
|
|
manually a `resource` configuration block for the resource, to which the
|
|
imported object will be mapped.
|
|
|
|
While this may seem tedious, it still gives Terraform users an avenue for
|
|
importing existing resources.
|
|
|
|
## Remote Backends
|
|
|
|
When using Terraform import on the command line with a [remote
|
|
backend](/docs/backends/types/remote.html), such as Terraform Cloud, the import
|
|
command runs locally, unlike commands such as apply, which run inside your
|
|
Terraform Cloud environment. Because of this, the import command will not have
|
|
access to information from the remote backend, such as workspace variables.
|
|
|
|
In order to use Terraform import with a remote state backend, you may need to
|
|
set local variables equivalent to the remote workspace variables.
