shell脚本批量删除docker镜像

平时我们下载了很多镜像.但这些镜像已经很老了,我们需要把原来的镜像删除,但如果镜像很多的话,手动删除会特别麻烦,我们可以写个脚本批量删除

[root@server script]# cat docker_deleteimage.sh 
#!/bin/bash
for i in `docker images | grep -v "IMAGE" | awk '{print $3}'` ##提取出镜像id
 do 
    {
    docker rmi -f $i &>/dev/null  ##删除镜像
    echo "docekr delete $i complete"
    } &
done
wait
echo -e "\e[1;31mdelete complete \e[0m" 
[root@server script]# docker images  ##现在这里有很多镜像
