如何衡量云硬盘的性能

操作前须知(重要)

警告
  • 本文使用 FIO 作为测试工具,请不要在系统盘上进行 FIO 测试,避免损坏系统重要文件。
  • 为避免底层文件系统元数据损坏导致数据损坏,请不要在业务数据盘上进行测试。请使用测试机器未存放业务数据的云硬盘进行压测,并提前创建快照保障您的数据安全。
  • 请确保/etc/fstab文件配置项中没有被测硬盘的挂载配置,否则将导致云服务器启动失败。

使用podman-compose快速部署应用

1. 什么是 Podman Compose?

Podman Compose 项目的目标是作为 Docker Compose 的替代品,而不需要对 docker-compose.yaml 文件进行任何修改。由于 Podman Compose 使用 吊舱(pod) 工作,所以最好看下“吊舱”的最新定义。

一个“ 吊舱(pod) ”(如一群鲸鱼或豌豆荚)是由一个或多个容器组成的组,具有共享的存储/网络资源,以及如何运行容器的规范。 Pods - Kubernetes 文档

(LCTT 译注:容器技术领域大量使用了航海比喻,pod 一词,意为“豆荚”,在航海领域指“吊舱” —— 均指盛装多个物品的容器。常不翻译,考虑前后文,可译做“吊舱”。)

如何在Mac上用Podman替换 Docker

1. 什么是 Docker?

Docker 是一个开源的应用容器引擎,属于 Linux 容器的一种封装,Docker 提供简单易用的容器使用接口,让开发者可以打包他们的应用以及依赖包到一个可移植的容器中,然后发布到任何流行的 Linux 机器上。容器是完全使用沙箱机制,相互之间不会有任何接口。

Docker 是目前很流行的 Linux 容器解决方案,即使 Docker 是目前管理 Linux 容器的一个非常方便的工具,但它也有两个缺点:

  • Docker 需要在你的系统上运行一个守护进程。
  • Docker 是以 root 身份在你的系统上运行该守护程序。

我希望你假定自己是雅思写作考官,根据雅思评判标准,按我给你的雅思考题和对应答案给我评分,并且按照雅思写作评分细则给出打分依据。此外,请给我详细的修改意见并写出满分范文。第一个问题是:It is sometimes argued that too many students go to university, while others claim that a university education should be a universal right.Discuss both sides of the argument and give your own opinion.对于这个问题,我的答案是:In some advanced countries, it is not unusual for more than 50% of young adults to attend college or university. Critics, however, claim that many university courses are worthless and young people would be better off gaining skills in the workplace. In this essay, I will examine both sides of this argument and try to reach a conclusion.There are several reasons why young people today believe they have the right to a university education. First, growing prosperity in many parts of the world has increased the number of families with money to invest in their children’s future. At the same time, falling birthrates mean that one- or two-child families have become common, increasing the level of investment in each child. It is hardly surprising, therefore, that young people are willing to let their families support them until the age of 21 or 22. Furthermore, millions of new jobs have been created in knowledge industries, and these jobs are typically open only to university graduates.However, it often appears that graduates end up in occupations unrelated to their university studies. It is not uncommon for an English literature major to end up working in sales, or an engineering graduate to retrain as a teacher, for example. Some critics have suggested that young people are just delaying their entry into the workplace, rather than developing professional skills.请依次给到我以下内容:具体分数及其评分依据、文章修改意见、满分范文。
