docker释放空标签镜像

1.查看空标签镜像

[root@k3s-storage my_app]# docker images -f dangling=true
REPOSITORY   TAG       IMAGE ID       CREATED              SIZE
<none>       <none>    fd6c16bb0dd9   About a minute ago   126MB

2.过滤镜像ID

[root@k3s-storage my_app]# docker images -f dangling=true -q 
fd6c16bb0dd9

3.根据镜像ID删除镜像

[root@k3s-storage my_app]# docker rmi -f $(docker images -f dangling=true -q)
