解决docker 日志文件过大的问题

修改daemon.json

$ nano /etc/docker/daemon.json
{
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "50m",
    "max-file": "3"
  }
}

$ systemctl daemon-reload
# 重启docker守护进程
$ systemctl restart docker

163 网易云镜像 配置

/etc/docker/daemon.json
{
  "registry-mirrors": ["http://hub-mirror.c.163.com"],
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "50m",
    "max-file": "3"
  }
}

已有日志清理

$ sudo du -d1 -h /var/lib/docker/containers | sort -h
# 对已有日志排序
$ sudo echo "" > log_file.log
# 清空已有日志
