How To Integrate Okta SSO with Chainguard Enforce

This documentation is related to Chainguard Enforce. You can request access to the product by selecting Chainguard Enforce on the inquiry form.

The Chainguard platform supports Single sign-on (SSO) authentication for users. By default, users can log in with GitHub, GitLab and Google, but SSO support allows users to bring their own identity provider for authentication.

This guide outlines how to create an Okta application and integrate it with Chainguard Enforce. After completing this guide, you’ll be able to log in to Chainguard Enforce using Okta and will no longer be limited to the default SSO options.

Prerequisites #

To complete this guide, you will need the following.

• chainctl installed on your system. Follow our guide on How To Install chainctl if you don’t already have this installed.
• An Okta account over which you have administrative access.

Create an Okta App integration #

To integrate your Okta identity provider with the Chainguard platform, log in to Okta and navigate to the Applications landing page in the Admin console. There, click the Create App Integration button.

Select OIDC - OpenID Connect as the sign-in method and Web Application as the application type.

Next, in the General Settings window, configure the application as follows.

• App integration name: Enter a descriptive name (like “Chainguard”) here.
• Logo: You can optionally add a Chainguard logo icon here to help your users visually identify this integration. If you’d like, you can use the icon from the Chainguard Enforce Console.
• Grant type: Ensure that the grant type is set to Authorization Code only.

Warning: DO NOT select other grant types as this may compromise your security.

• Sign-in redirect URIs: Set the redirect URI to https://issuer.enforce.dev/oauth/callback
• Sign-out redirect URIs: This will have a URI field set to http://localhost:8080 by default. Click the X icon to remove the sign-out redirect entirely, leaving this field blank.

Click the Save button. Then, select the Sign On tab. Find the OpenID Connect ID Token section and click the Edit button.

Set the Issuer option to Okta URL, then click the Save button.

That completes our configuration of the Okta Application. Next, we need to configure the Chainguard platform to use our Okta application.

Configuring Chainguard to use Okta SSO #

To configure the platform, make a note of the following settings from your Okta Application:

• Client ID: You can find this on the General tab under Client Credentials
• Client Secret: Find this on the General Tab under Client Credentials
• Issuer URL: This is found under the Sign on tab in the OpenID Connect ID Token section

Next, log in to Chaingaurd with chainctl, using an OIDC provider like Google, Github, or GitLab to bootstrap your account.

chainctl auth login

Note that this bootstrap account can be used as a backup account (that is, a backup account you can use to log in if you ever lose access to your primary account). However, if you prefer to remove this rolebinding after configuring the custom IDP, you may also do so.

Lastly, create a new identity provider using the Okta application details you noted previously.

export NAME=okta
export CLIENT_ID=<your client id here>
export CLIENT_SECRET=<your client secret here>
export ISSUER=<your issuer url here>
chainctl iam identity-provider create \
  --configuration-type=OIDC \
  --oidc-client-id=${CLIENT_ID} \
  --oidc-client-secret=${CLIENT_SECRET} \
  --oidc-issuer=${ISSUER} \
  --oidc-additional-scopes=email \
  --oidc-additional-scopes=profile \
  --name=${NAME}

You’ll be prompted to select a Chainguard IAM group under which to install your identity provider. Your selection won’t affect how your users authenticate but will have implications on who has permission to modify the SSO configuration.
