全局设置
通过对Docker服务配置文件修改，设置全局配置
vi /etc/docker/daemon.json { "log-driver": "json-file", "log-opts": { "max-size": "50m", "max-file": "1" } } systemctl daemon-reload systemctl restart docker
人工清理已经存在的日志
查看所有容器的日志
1 2 3 4 5 6 7 8 9 | #!/bin/sh echo "======== docker containers logs file size ========" logs=$(find /var/lib/docker/containers/ -name *-json.log) for log in $logs do ls -lh $log done |
cat方式可以清空当前日志，以后输出的日志会继续写入；
1 2 3 4 5 6 7 8 9 | #!/bin/sh echo "======== start clean docker containers logs ========" logs=$(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 ========" |
