Use these instructions set up Google as your SSO provider for Tonic.
To configure Google SSO:
- 2.Create and configure a service account to read user groups - In addition to the above, requires the Google workspace administrator.
The OAuth client ID is sufficient to enable logging in with your Google account, but no groups are parsed. If the service account is misconfigured, the login succeeds without the groups being parsed and a warning is logged to the server with more details. For the provided links, it is assumed that the user is logged into their administrative account and using the same project.
- 2.Click Create credentials, located near the top.
Create Credentials option for Google
- 3.Select OAuth client ID.
Create OAuth Client ID panel
- 4.Select Web application as the application type.
- 5.Choose a name.
- 6.Under Authorized redirect URIs, add the URL of the Tonic server with the endpoint /sso/callback.
- For example, a local tonic server at http://localhost:3000 would need http://localhost:3000/sso/callback to be set as the redirect URI
- Also note that internal URLs might not work:
- 7.Note the client ID and client secret. You will need to provide them to Tonic.
TONIC_SSO_CLIENT_ID: <client id of oauth credentials>
TONIC_SSO_CLIENT_SECRET: <client secret of oauth credentials>
To set up the service account:
For official documentation, see https://cloud.google.com/iam/docs/creating-managing-service-accounts and https://cloud.google.com/iam/docs/creating-managing-service-account-keys.

- 3.Skip all the subsequent optional steps.
- 4.After you create the service account, select it and go into the Keys tab.
- 5.Select Add Key -> Create new key and select JSON as the key type. The browser automatically downloads a json file.
- 6.The json file must be base64 encoded to set it as a variable in your Docker Compose file. An example command to do this is:
cat /path/to/json/file | base64 -w 0The long output of this command is set as the value of
TONIC_SSO_SERVICE_ACCOUNT_JSON_BASE64in the Docker Compose file

TONIC_SSO_SERVICE_ACCOUNT_JSON_BASE64: <base64 encoded json key>
TONIC_SSO_DOMAIN: <domain name>
TONIC_SSO_GROUP_FILTER_REGEX: <regex string>
The domain name is the workspace domain. For example, for [email protected], the domain is
The group filter regex is an expression that matches the groups that you want Tonic to be aware of. You can change this later. For example, the expression
.*Tonic.*allows all groups that contain the word "Tonic".
