Chapter 4. Enable and configure the Keycloak plugin

Procedure

1. To configure the Keycloak plugin, add the following in your app-config.yaml file:

   schedule

   Configure the schedule frequency, timeout, and initial delay. The fields support cron, ISO duration, "human duration" as used in code.

        catalog:
          providers:
            keycloakOrg:
              default:
                schedule:
                  frequency: { minutes: 1 }
                  timeout: { minutes: 1 }
                  initialDelay: { seconds: 15 }

   userQuerySize and groupQuerySize

   Optionally, configure the Keycloak query parameters to define the number of users and groups to query at a time. Default values are 100 for both fields.

      catalog:
        providers:
          keycloakOrg:
            default:
              userQuerySize: 100
              groupQuerySize: 100

   Authentication

   Communication between Developer Hub and Keycloak is enabled by using the Keycloak API. Username and password, or client credentials are supported authentication methods.

   The following table describes the parameters that you can configure to enable the plugin under catalog.providers.keycloakOrg.<ENVIRONMENT_NAME> object in the app-config.yaml file:
