[keycloak-user] how to make export with standalone.xml

Due to the lack of documentation and resources to make a realm export into a docker container and after hours of search on the net without getting any solution, I found a similar question : * http://keycloak-user.88327.x6.nabble.com/keycloak-user-How-to-stop-the-ke... <http://keycloak-user.88327.x6.nabble.com/keycloak-user-How-to-stop-the-ke... Is there any link or example to make the export with some config of standalone.xml?
