[keycloak-user] Adapter installation

I'm setting up a docker container with keycloak. now i want to install the adapters, the usual way of installing is via ${JBOSS_HOME}/bin/jboss-cli.sh -c --file=${JBOSS_HOME}/bin/adapter-install.cli but therefore jboss needs to be running already, which is not good/possible on this step. is there a offline way of installing the adapters?
