清理docker标准输出与无用镜像

#!/bin/bash
logs=$(find /var/lib/docker/containers -name *-json.log)
for log in ${logs}
do
    cat /dev/null > ${log}
done

images=$(docker images | grep -v yqn-library | awk '{print $3}' | grep -v "IMAGE")
for image in ${images}
do
    docker rmi ${image}
done

docker system prune -f

查找docker中临时存储占比top10的容器

#!/bin/bash
cd /var/lib/docker/overlay2/
paths=$(du -shm * | sort -rnk1 | awk '{print $NF}' |head)
docker_containers=$(docker ps -qa)
for path in ${paths}
do
    for docker_container in ${docker_containers}
    do
        docker inspect ${docker_container} | grep ${path} > /dev/null
        if [[ $? -eq 0 ]];then
           echo ${docker_container}  ${path}
        fi
    done
done
