GitLab SSO

Learn how to configure GitLab SSO for Infisical.

Using GitLab SSO on a self-hosted instance of Infisical requires configuring an OAuth application in GitLab and registering your instance with it.

1. Create an OAuth application in GitLab

   Navigate to your user Settings > Applications to create a new GitLab application.

   

   Create the application. As part of the form, set the Redirect URI to https://your-domain.com/api/v1/sso/gitlab. Note that only read_user is required as part of the Scopes configuration.

   

   If you have a GitLab group, you can create an OAuth application under it in your group Settings > Applications.

2. Add your OAuth application credentials to Infisical

   Obtain the Application ID and Secret for your GitLab application.

   

   Back in your Infisical instance, make sure to set the following environment variables:

   • CLIENT_ID_GITLAB_LOGIN: The Client ID of your GitLab application.
   • CLIENT_SECRET_GITLAB_LOGIN: The Secret of your GitLab application.
   • (optional) URL_GITLAB_LOGIN: The URL of your self-hosted instance of GitLab where the OAuth application is registered. If no URL is passed in, this will default to https://gitlab.com.
   • AUTH_SECRET: A secret key used for signing and verifying JWT. This can be a random 32-byte base64 string generated with openssl rand -base64 32.
   • SITE_URL: The URL of your self-hosted instance of Infisical - should be an absolute URL including the protocol (e.g. https://app.infisical.com)

   Once added, restart your Infisical instance and log in with GitLab.

FAQ

Why is GitLab SSO not working?

It is likely that you have misconfigured your self-hosted instance of Infisical. You should:

• Check that you have set the CLIENT_ID_GITLAB_LOGIN, CLIENT_SECRET_GITLAB_LOGIN, AUTH_SECRET, and SITE_URL environment variables.
• Check that the Redirect URI specified in GitLab matches the SITE_URL environment variable. For example, if the former is https://app.infisical.com/api/v1/sso/gitlab then the latter should be https://app.infisical.com.
