docker 清除日志

新建一个查看日志大小的sh

findjsonlog.sh

#!/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  

新建 一个cleanlog.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 ========" 

执行 sudo ./cleanlog.sh   可以清除docker 服务的日志

限制单个容器的日志大小 的办法，在容器运行时加上参数：--log-driver json-file --log-opt max-size=10m
