Using the SAML 2.0 standard, you can configure single sign-on (SSO) for a number of cloud apps. After you set up SSO, your users can use their Google Workspace credentials to sign in to an app using SSO.
Use SAML to set up SSO for Buildkite
You must be signed in as a super administrator for this task.
Step 1: Set up Google as a SAML identity provider-
Sign in to your Google Admin console.
Sign in using an account with super administrator privileges (does not end in @gmail.com).
-
In the Admin console, go to Menu
Apps
Web and mobile apps.
-
Click Add app
-
For Enter app name, enter Buildkite.
-
In the search results, point to Buildkite and click Select.
-
In the Google Identity Provider details window, for Option 2: Copy the SSO URL, entity ID, and certificate:
- Next to SSO URL, click Copy
and save the URL.
- Next to Certificate, click Copy
You need these details to complete the setup in Buildkite.
- Next to SSO URL, click Copy
-
Click Continue.
- On the Service provider details page, edit the ACS URL, replacing {uniqueid-provided-by-sp} with the Unique ID of your Buildkite account, and click Continue.
-
(Optional) To add additional mappings, click Add Mapping and select the fields that you need to map.
-
(Optional) To enter group names that are relevant for this app:
- For Group membership (optional), click Search for a group, enter one or more letters of the group name, and select the group name.
- Add additional groups as needed (maximum of 75 groups).
- For App attribute, enter the corresponding groups attribute name of the service provider.
Regardless of how many group names you enter, the SAML response includes only groups that a user is a member of (directly or indirectly). For more information, go to About group membership mapping.
- Click Finish.
- Send an email to Buildkite support asking them to enable SSO for your account. Include your organization’s email domain and the following information you copied from Google in Step 1:
- SSO URL
- Certificate (attached as a text file)
Once Buildkite has set up SSO for your account, you can sign in to Buildkite to verify that it’s enabled.
- Sign in to your Buildkite account as administrator.
- On the left, click Settings
You should see a message verifying that SSO is enabled and showing the login URL for your organization.
