docker清理none image

概述

本地出现none image是由于构建过程异常导致残存的image,占用空间,看着不舒服

解决

• https://docs.docker.com/engine/reference/commandline/images/#filtering

#docker images --filter
the currently supported filters are:

dangling (boolean - true or false)  //none
label (label=<key> or label=<key>=<value>)
before (<image-name>[:<tag>], <image id> or <image@digest>) - filter images created before given id or references
since (<image-name>[:<tag>], <image id> or <image@digest>) - filter images created since given id or references

docker rmi $(docker images -f 'dangling=true' -q)
