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
#!/bin/sh
echo "======== docker containers logs file size ========"
logs=$(find /var/lib/docker/containers/ -name *-json.log)
for log in $logs
do
ls -lh $log
done
cat方式可以清空当前日志，以后输出的日志会继续写入；
#!/bin/sh
echo "======== start clean docker containers logs ========"
logs=$(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 ========"
