Hi Yegui, As Keycloak is based on Wildfly, they share the same deployment semantics. https://docs.jboss.org/author/display/WFLY/Application+deployment In a few words: there's no "deployments" equivalent in domain mode. You should deploy applications either via jboss-cli, or via Wildfly admin GUI. See also this thread on deploying JDBC drivers in domain mode: https://developer.jboss.org/thread/276077 Cheers, Dmitry Telegin CTO, Acutus s.r.o.
