Docker容器日志查看与清理的方法(亲测有效)

#!/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 

# chmod +x docker_log_size.sh

# ./docker_log_size.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 ========" 

# chmod +x clean_docker_log.sh

# ./clean_docker_log.sh
