一个日志清理脚本clean_docker_log.sh，内容如下：

#!/bin/sh

echo “======== start clean docker containers logs ========”

logs=$(find /var/lib/docker/containers/ -name *-json.log)

for log in $logs
do
echo “clean logs : $log”
cat /dev/null > $log
done

echo “======== end clean docker containers logs ========”

#chmod +x clean_docker_log.sh

#./clean_docker_log.sh
