Steps on Keycloak Admin Console

Creating a Client

Here, we will add Devtron as a client for using Keycloak SSO.

1. In the Admin Console, go to Clients and click Create client.

   

   Figure 1: Creating Client on Keycloak
2. Within General Settings:

   • Enter devtron in the Client ID field. We will use this ID while configuring SSO later in Devtron.

   • Enter Devtron in the Name field.

   

   Figure 2: Client ID and Name
3. Within Capability config, turn on Client Authentication.

   

   Figure 3: Enabling Client Authentication Toggle
4. Within Login settings, enter https://<DEVTRON_BASE_URL>/orchestrator/api/dex/callback in the following fields.

   • Valid redirect URIs

   • Valid post logout redirect URIs

   • Web origins

   Click here to know where to find DEVTRON_BASE_URL.

2. Use the copy button next to the Client Secret field and paste it somewhere for future reference.

Creating Users

Here, we will create a user that can log in to Devtron via SSO. We will assign a username and password that the user can enter while logging in to Devtron via Keycloak SSO.

1. In the Admin Console, go to Users and click Add user.

2. Give a username (e.g., usertest) in the Username field and enter the user's email address (e.g., [e-mail]) in the Email field.

Steps on Devtron

Configuring OIDC SSO

Who Can Perform This Action?

Users need to have super-admin permission to configure SSO.

Here, we will set up an OIDC SSO and enter the values we obtained in the previous section.

1. Go to Global Configurations → SSO Login Services → OIDC.

   

   Figure 10: Choosing OIDC SSO
2. Below the URL field, take the help of the Click to use option to populate the exact URL if the displayed one is incorrect.

   

   Figure 11: Populating Correct Orchestrator URL
3. In the Configuration editor, do the following:

   • In the issuer field, paste the URL you got while retrieving issuer URL.

   • In the clientID field, paste the ID you entered while creating the client.

   • In the clientSecret field, paste the secret you got under client credentials tab.

   • In the redirectURI field, make sure to enter the same redirect URI you gave in step 4 of client creation.

4. Click Save or Update to activate Keycloak SSO login.

Adding Users

Who Can Perform This Action?

Users need to have super-admin permission to add users.

Here, we will add the user we created in the Keycloak Admin Console. If this step is skipped, the user might not be able to log in to Devtron via Keycloak.

1. Go to Global Configurations → Authorization → User Permissions.

2. Click + Add Users.

   

   Figure 13: Adding Users to Devtron
3. In the Email addresses field, enter the email address of the user you created in Keycloak.

   

   Figure 14: Entering User Data and Permissions
4. Assign necessary permissions to this new user. Refer user permissions to know more.

5. Click Save.

Now, you may log out and test the Keycloak OIDC login method using the user credentials. Clicking the Login with Oidc button will land you on Keycloak's login page.
