# Application secrets
|
|
|
|
This page is a development guide for application secrets.
|
|
|
|
## Secret entries
|
|
|
|
|Entry |Description |

|

|
|`secret_key_base` | The base key to be used for generating a various secrets |
|
|
| `otp_key_base` | The base key for One Time Passwords, described in [User management](../raketasks/user_management.md#rotate-two-factor-authentication-encryption-key) |
|
|
|`db_key_base` | The base key to encrypt the data for `attr_encrypted` columns |
|
|
|`openid_connect_signing_key` | The singing key for OpenID Connect |
|
|
|
|
## Where the secrets are stored
|
|
|
|
|Installation type |Location |
|
|
|--- |--- |
|
|
|Omnibus |[`/etc/gitlab/gitlab-secrets.json`](https://docs.gitlab.com/omnibus/settings/backups.html#backup-and-restore-omnibus-gitlab-configuration) |
|
|
|Cloud Native GitLab Charts |[Kubernets Secrets](https://gitlab.com/gitlab-org/charts/gitlab/-/blob/f65c3d37fc8cf09a7987544680413552fb666aac/doc/installation/secrets.md#gitlab-rails-secret)|
|
|
|Source |`<path-to-gitlab-rails>/config/secrets.yml` (Automatically generated by [01_secret_token.rb](https://gitlab.com/gitlab-org/gitlab/-/blob/master/config/initializers/01_secret_token.rb)) |
|
|
|
|
## Warning: Before you add a new secret to application secrets
|
|
|
|
Before you add a new secret to [`config/initializers/01_secret_token.rb`](https://gitlab.com/gitlab-org/gitlab/-/blob/master/config/initializers/01_secret_token.rb),
|
|
make sure you also update Omnibus GitLab or updates will fail. Omnibus is responsible for writing the `secrets.yml` file.
|
|
If Omnibus doesn't know about a secret, Rails will attempt to write to the file, but this will fail because Rails doesn't have write access.
|
|
The same rules apply to Cloud Native GitLab charts, you must update the charts at first.
|
|
In case you need the secret to have same value on each node (which is usually the case) you need to make sure it's configured for all
|
|
GitLab.com environments prior to changing this file.
|
|
|
|
**Examples**
|
|
|
|
- [Change for source installation](https://gitlab.com/gitlab-org/gitlab-foss/-/merge_requests/27581)
|
|
- [Change for omnibus installation](https://gitlab.com/gitlab-org/omnibus-gitlab/-/merge_requests/3267)
|
|
- [Change for omnibus installation](https://gitlab.com/gitlab-org/omnibus-gitlab/-/merge_requests/4158)
|
|
- [Change for Cloud Native installation](https://gitlab.com/gitlab-org/charts/gitlab/-/merge_requests/1318)
|
|
|
|
## Further iteration
|
|
|
|
We might deprecate/remove this automatic secret generation '01_secret_token.rb' in the future.
