docker 清除日志文件

查看日志大小：在linux系统中 创建docker_logs.sh文件，输入 sh docker_logs.sh 命令查看日志文件大小

/var/lib/docker/containers为docker默认日志输出路径

echo "======== docker containers logs file size ========"  
logs=$(find /var/lib/docker/containers/ -name *-json.log)
for log in $logs
	do
		ls -lh $log
	
	done

清空日志文件：创建clear_docker_logs.sh文件，输入 sh clear_docker_logs.sh 命令清空日志文件

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