[keycloak-dev] Extension for Health-Checks in Keycloak

Hello group, I wrote a small Keycloak extension [0] that exposes a health endpoint with health-checks as a RealmResource. Health Checks can be contributed with a dedicated SPI. (I took some inspiration from Spring Boot and Wildfly Swarm Health-Checks: [1]) I'm now looking for general feedback and suggestions for additional health checks that could be added (infinispan?) - perhaps this could even be added to Keycloak directly. Some things I noticed: 1) RealmResourceProvider allows to expose custom JAX-RS resources on realm level but there is no equivalent for "global" Resources, e.g. something like KeycloakResourceProvider / PublicResourceProvider is missing. I wanted to add health-check for the whole Keycloak Server not just a realm... 2) It seems that many requests lead to a database tx being commited via org.keycloak.services.filters.KeycloakTransactionCommitter, even if there is no write to the database. Is this intended? 3) The keycloak-server BOMs didn't work for me. Even if I declare <dependencyManagement> <dependencies> <dependency> <groupId>org.keycloak.bom</groupId> <artifactId>keycloak-spi-bom</artifactId> <version>${keycloak.version}</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> in my pom.xml I need to provide <version> settings to keycloak dependencies, e.g. <dependency> <groupId>org.keycloak</groupId> <artifactId>keycloak-server-spi-private</artifactId> <version>${keycloak.version}</version> </dependency> which shouldn't be the case with a correct maven BOM. I tried this with keycloak version 2.5.5.Final and 3.0.0.Final Cheers, Thomas [0] https://github.com/thomasdarimont/keycloak-health-checks [1] https://wildfly-swarm.gitbooks.io/wildfly-swarm-users-guide/advanced/moni...
