thanks for answer. i use docker rm -f containername to delete the container.

maybe i have get the answer. my condition is my container mount a ceph file。when i delete my container。the ceph file ，i didnt unmount it。so，when i use ps -ef。 i get the process is stilling in my system。and i use kill -9 processid. i cant kill the process. so maybe the ceph dead process hold resouce。 it make the container ip still not release。 my companion suggest reboot machine 。
