关于KEYCLOAK_FRONTEND_URL: unbound variable异常问题

在docker下安装keycloak下，出现异常问题如下：

Added 'keycloak' to '/opt/jboss/keycloak/standalone/configuration/keycloak-add-user.json', restart server to load user
/opt/jboss/tools/docker-entrypoint.sh: line 47: KEYCLOAK_FRONTEND_URL: unbound variable

解决方案：

重新升级 docker pull jboss/keycloak
