解决docker空间已满（清除containers下日志）

容器太多的时候单独删除太麻烦，可用脚本（脚本放到containers目录下执行）：

echo "======== docker containers logs file size ========"
logs=$(find ./ -name *-json.log)
for log in $logs
        do
             ls -lh $log
        done

echo "======== start clean docker containers logs ========"
logs=$(find ./ -name *-json.log)
for log in $logs
        do
                echo "clean logs : $log"
                cat /dev/null > $log
        done
echo "======== end clean docker containers logs ========"
