限制大小，在得到服务器时，容器创建前，设置全局限制。
# vim /etc/docker/daemon.json { "registry-mirrors": ["http://f613ce8f.m.daocloud.io"], "log-driver":"json-file", "log-opts": {"max-size":"500m", "max-file":"3"} }
日志清理处理：
新建文件 clean_docker_log.sh
[root@izm5ej4bsah4npfgi5wl3vz soft]# vi clean_docker_log.sh #!/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 ========"
