# Provision Terraform infrastructure for AWS

<Warning>
  A Domino install can’t be hosted on a subdomain of another Domino install. For example, if you have Domino deployed at `data-science.example.com`, you can’t deploy another instance of Domino at `acme.data-science.example.com`.
</Warning>

## Provision your infrastructure with Domino’s recommended Terraform module

Domino strongly recommends that you use our specialized [Terraform module](https://github.com/dominodatalab/terraform-aws-eks/tree/v3.27.0) designed for AWS, which is publicly accessible.

This module offers an efficient method for provisioning your environment, and it can also serve as a reference if you opt for manual infrastructure setup.

<Note>
  If you encounter the following error when running [set-mod-version.sh](https://github.com/dominodatalab/terraform-aws-eks/blob/v3.27.0/examples/deploy/set-mod-version.sh):

  `Error: The MOD_VERSION v3.27.0 is not a suitable tag for the modules source.`

  set the `MOD_VALIDATION_OFF` variable in your shell, for example:

  export MOD\_VALIDATION\_OFF=true
</Note>

## Validated module versions

For Domino version `6.3`, we have validated compatibility with Terraform module version `v3.27.0`. When following the deployment instructions, please use `MOD_VERSION=v3.27.0`. Detailed instructions can be found at [Deploy using a module](https://github.com/dominodatalab/terraform-aws-eks/tree/v3.27.0#bootstrap-module).

## Karpenter support

Starting with module version v3.26.1, the Domino Terraform module supports Karpenter. Instructions can be found in the [module documentation](https://github.com/dominodatalab/terraform-aws-eks/tree/v3.27.0#karpenter).
