nginx 官方 docker 镜像日志文件的映射保存

docker 镜像内路径：/var/log/nginx

在 nginx.conf 中配置日志按时间生成（在 server 节点中插入以下配置，未验证）：

if ($time_iso8601 ~ "^(d{4})-(d{2})-(d{2})T(d{2}):(d{2}):(d{2})")
{
    set $year $1;
    set $month $2;
    set $day $3;
    set $hour $4;
    set $minutes $5;
    set $seconds $6;
}
#访问日志 按小时
access_log /var/log/nginx/$year-$month-$day-access.log;
#错误日志
error_log /var/log/nginx/$year-$month-$day-error.log;
