docker之如何设置日志文件大小及个数

docker run --log-opt max-size=10m --log-opt max-file=3

{
    "log-driver": "json-file",
    "log-opts": {
        "max-size": "50m",
        "max-file": "1"
    }
}

systemctl daemon-reload
systemctl restart docker

#!/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 ========"

{
  "log-driver": "json-file",
  "log-opts": {"max-size": "5m", "max-file": "3"}
}

systemctl reload docker
