# Terraform state administration (alpha) **(FREE)**
> [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/2673) in GitLab 12.10.
GitLab can be used as a backend for [Terraform](../user/infrastructure/index.md) state
files. The files are encrypted before being stored. This feature is enabled by default.
The storage location of these files defaults to:
- `/var/opt/gitlab/gitlab-rails/shared/terraform_state` for Omnibus GitLab installations.
- `/home/git/gitlab/shared/terraform_state` for source installations.
These locations can be configured using the options described below.
Use [external object storage](https://docs.gitlab.com/charts/advanced/external-object-storage/#lfs-artifacts-uploads-packages-external-diffs-pseudonymizer-terraform-state-dependency-proxy) configuration for [GitLab Helm chart](https://docs.gitlab.com/charts/) installations.
## Using local storage
The default configuration uses local storage. To change the location where
Terraform state files are stored locally, follow the steps below.
**In Omnibus installations:**
1. To change the storage path for example to `/mnt/storage/terraform_state`, edit
`/etc/gitlab/gitlab.rb` and add the following line:
```ruby
gitlab_rails['terraform_state_storage_path'] = "/mnt/storage/terraform_state"
```
1. Save the file and [reconfigure GitLab](restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect.
**In installations from source:**
1. To change the storage path for example to `/mnt/storage/terraform_state`, edit
`/home/git/gitlab/config/gitlab.yml` and add or amend the following lines:
```yaml
terraform_state:
enabled: true
storage_path: /mnt/storage/terraform_state
```
1. Save the file and [restart GitLab](restart_gitlab.md#installations-from-source) for the changes to take effect.
## Using object storage **(FREE SELF)**
Instead of storing Terraform state files on disk, we recommend the use of [one of the supported object
storage options](object_storage.md#options). This configuration relies on valid credentials to
be configured already.
[Read more about using object storage with GitLab](object_storage.md).
### Object storage settings
The following settings are:
- Nested under `terraform_state:` and then `object_store:` on source installations.
- Prefixed by `terraform_state_object_store_` on Omnibus GitLab installations.
| Setting | Description | Default |
|---------|-------------|---------|
| `enabled` | Enable/disable object storage | `false` |
| `remote_directory` | The bucket name where Terraform state files are stored | |
| `connection` | Various connection options described below | |
### S3-compatible connection settings
See [the available connection settings for different providers](object_storage.md#connection-settings).
**In Omnibus installations:**
1. Edit `/etc/gitlab/gitlab.rb` and add the following lines; replacing with
the values you want:
```ruby
gitlab_rails['terraform_state_object_store_enabled'] = true
gitlab_rails['terraform_state_object_store_remote_directory'] = "terraform"
gitlab_rails['terraform_state_object_store_connection'] = {
'provider' => 'AWS',
'region' => 'eu-central-1',
'aws_access_key_id' => 'AWS_ACCESS_KEY_ID',
'aws_secret_access_key' => 'AWS_SECRET_ACCESS_KEY'
}
```
NOTE:
If you are using AWS IAM profiles, be sure to omit the AWS access key and secret access key/value pairs.
```ruby
gitlab_rails['terraform_state_object_store_connection'] = {
'provider' => 'AWS',
'region' => 'eu-central-1',
'use_iam_profile' => true
}
```
1. Save the file and [reconfigure GitLab](restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect.
1. Migrate any existing local states to the object storage (GitLab 13.9 and later):
```shell
gitlab-rake gitlab:terraform_states:migrate
```
**In installations from source:**
1. Edit `/home/git/gitlab/config/gitlab.yml` and add or amend the following
lines:
```yaml
terraform_state:
enabled: true
object_store:
enabled: true
remote_directory: "terraform" # The bucket name
connection:
provider: AWS # Only AWS supported at the moment
aws_access_key_id: AWS_ACESS_KEY_ID
aws_secret_access_key: AWS_SECRET_ACCESS_KEY
region: eu-central-1
```
1. Save the file and [restart GitLab](restart_gitlab.md#installations-from-source) for the changes to take effect.
1. Migrate any existing local states to the object storage (GitLab 13.9 and later):
```shell
sudo -u git -H bundle exec rake gitlab:terraform_states:migrate RAILS_ENV=production
```
