Good morning, I've been working on some ideas for AeroGear, in order to have UPS and Keycloak in a separated infrastructure. The reason why this is not possible today, is pretty much related with design decisions in the past for UPS. Not sure if this makes some sense or was already discussed. But I was wondering if we could change the adapters to load an environment variable like ${keycloak.server.url}. The raw idea is pretty simple: ## Configure the system variable on Wildfly $JBOSS_HOME/bin/jboss-cli.sh -c --controller=localhost:9992 --command="/system-property=keycloak.server.url:add(value=http://localhost:8083)" Or just configuring it inside standalone.xml like Hawkular already does (http://www.hawkular.org/docs/user/installation-guide.html#_preparing_the_...) ## Pass the variable as argument { "realm" : "aerogear", "auth-server-url" : "${keycloak.server.url}", "ssl-required" : "external", "resource" : "unified-push-server", "bearer-only" : true, "disable-trust-manager" : true } I couldn't find any history related to this topic, besides this ticket (https://issues.jboss.org/browse/KEYCLOAK-1289). Do you think this is doable to implement? Or am I missing something? -- - abstractj
