Prerequisites

• Install and configure Keycloak on your server or cloud environment.

• Create a new realm in Keycloak for your application.

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.
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.
3. Within Capability config, turn on Client Authentication.
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.
5. Click Save.

Getting Client Secret

Here, we will obtain the secret we need while configuring SSO in Devtron.

1. Go to the Credentials tab of the client you created.
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., usertest@example.com) in the Email field.
3. Click Create. Your user creation will be successful.

4. Go to the Credentials tab of the user you created.
5. Click Set password.

6. Enter the password and confirm it.

7. Click Save.

Retrieving Issuer URL

Here, we will obtain the Issuer URL we need while configuring SSO in Devtron.

1. In the Admin Console, go to Realm settings.

2. In the General tab, scroll down to the Endpoints field, and click the OpenID Endpoint Configuration link.
3. This will open a new page, copy the value of the key named issuer, and paste it somewhere for future reference.

Steps on Devtron

Configuring OIDC 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.
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.
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

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.
3. In the Email addresses field, enter the email address of the user you created in Keycloak.
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.

Sample Configuration

Values You Would Require at SSO Provider

Devtron provides a sample configuration out of the box. There are some values that you need to either get from your SSO provider or give to your SSO provider.

Values to Fetch

• clientID

• clientSecret

Values to Provide

• redirectURI (provided in SSO Login Services by Devtron)

Reference

Prerequisites

A verified account on Okta. Okta activates your account only if email verification is successful.

Here's a reference guide to set up your Okta org and application: Link

Tutorial

Steps on Okta Admin Console

Once your Okta org is set up, create an app integration on Okta to get a Client ID and Client Secret.

1. In the Admin Console, go to Applications → Applications.

2. Click Create App Integration.

3. Select OIDC - OpenID Connect as the Sign-in method.

1. Select Web as the application type and click Next.

2. On the App Integration page:

   • Give a name to your application.

   • Select the Interaction Code and Refresh Token checkbox.

   • Now go to Devtron's Global Configurations → SSO Login Services → OIDC.

   • Copy the redirect URI given in the helper text (might look like: https://xxx.xxx.xxx/xxx/callback).

   • Return to the Okta screen, and remove the prefilled value in Sign-in redirect URIs.

   • Paste the copied URI in Sign-in redirect URIs.

   • Click Save.

3. On the General tab:

   • Note the Client ID value.

   • Click the Edit option.

   • In Client Authentication, choose Client Secret.

   • Click Save.

   • Click Generate new secret.

   • Note the Client Secret value.

Steps on Devtron

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

2. In the URL field, enter the Devtron application URL (a valid https link) where it is hosted.

3. Under Configuration tab, locate the config object, and provide the clientID and clientSecret of the app integration you created on Okta.

4. Add a key insecureSkipEmailVerified: true. Note that this key is only required for Okta SSO. For other types of OIDC SSO, refer OIDC supported configurations.

5. Provide issuer value as https://${yourOktaDomain}. Replace ${yourOktaDomain} with your domain on Okta as shown in the video.

6. For providing redirectURI or callbackURI registered with the SSO provider, you can either select Configuration or Sample Script. Note that the redirect URI is already given in the helper text (as seen in the previous section).

7. Click Save to create and activate Okta SSO login.

Now your users will be able to log in to Devtron using the Okta authentication method. Note that existing signed-in users will be logged out and they have to log in again using their OIDC account.
