docker build -f Dockerfile -t xxx-weiba-service:latest .

docker run -it --rm --name xxx-weiba-service -h xxx-weiba-service -p 33333:8080 -e sproc_host=10.88.17.200:30001 -e nacos_host=192.168.160.4:26061 -e mqtt_host=192.168.216.1:32747 -e gate_host=192.168.216.1:30083 --privileged=true xxx-weiba-service:latest
