rancher-记一次无法启动

发表于 | 分类于

docker容器日志过多，导致磁盘空间耗尽。从而rancher server无法启动。记录关键命令。

  1. 查看容器相关信息: docker inspect 容器id

  2. 查看磁盘占用大小信息： df -h

  3. 查看目录占用总大小: du -hs 目录

  4. 列举容器日志大小：ls -lh $(find /var/lib/docker/containers/ -name *-json.log)

  5. 清除日志脚本

    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   =========================="
