Kubernetes与Docker:真正的意思是什么? [英] Kubernetes vs. Docker: What Does It Really Mean?

问题描述

我知道Docker和Kubernetes不是直接竞争对手. Docker是容器平台，容器由工具Kubernetes协调和调度.

I know that Docker and Kubernetes aren’t direct competitors. Docker is the container platform and containers are coordinated and scheduled by Kubernetes, which is a tool.

这实际上是什么意思，我如何在适用于Azure的Docker上部署我的应用程序?

What does it really mean and how can I deploy my app on Docker for Azure ?

推荐答案

简短答案:

• Docker(通常是容器)解决了打包应用程序及其依赖项的问题.这使得在任何地方都可以轻松运输和运行.

  Short answer:

  • Docker (and containers in general) solve the problem of packaging an application and its dependencies. This makes it easy to ship and run everywhere.

    Kubernetes是容器之上的抽象层.这是一个控制/管理容器的分布式系统.

    Kubernetes is one layer of abstraction above containers. It is a distributed system that controls/manages containers.

    我的建议:因为风景很大，所以...开始学习并解决难题通过遵循课程一起学习.下面，我添加了来自以下内容的一些信息:

    My advice: because the landscape is huge... start learning and putting the pieces of the puzzle together by following a course. Below I have added some information from the:

    在质量保证(QA)环境中，我们可以避免在单个主机上运行容器来开发和测试应用程序.但是， 当我们投入生产时，我们没有相同的自由 ，因为我们需要确保我们的应用程序:

    In the quality assurance (QA) environments, we can get away with running containers on a single host to develop and test applications. However, when we go to production, we do not have the same liberty, as we need to ensure that our applications:

    • 容错
    • 可以扩展，并按需执行
    • 最佳利用资源
    • 可以自动发现其他应用程序，并彼此通信
    • 可以从外部访问
    • 可以在不停机的情况下进行更新/回滚.
    • Are fault-tolerant
    • Can scale, and do this on-demand
    • Use resources optimally
    • Can discover other applications automatically, and communicate with each other
    • Are accessible from the external world
    • Can update/rollback without any downtime.

    容器协调器 是将主机分组在一起以形成集群的工具，可帮助我们满足上述要求.

    Container orchestrators are the tools which group hosts together to form a cluster, and help us fulfill the requirements mentioned above.

    如今，有许多容器协调器可用，例如:

    Nowadays, there are many container orchestrators available, such as:

    • Docker Swarm::Docker Swarm是由Docker，Inc.提供的容器编排器.它是Docker Engine的一部分.
    • Kubernetes: Kubernetes由Google创建，但是现在它是Cloud Native Computing Foundation项目的一部分.
    • Mesos Marathon: Marathon是在Apache Mesos上大规模运行容器的框架之一.
    • Amazon ECS::Amazon EC2容器服务(ECS)是AWS提供的托管服务，用于在其基础设施上大规模运行Docker容器.
    • Hashicorp Nomad: Nomad是HashiCorp提供的容器协调器.
    • Docker Swarm: Docker Swarm is a container orchestrator provided by Docker, Inc. It is part of Docker Engine.
    • Kubernetes: Kubernetes was started by Google, but now, it is a part of the Cloud Native Computing Foundation project.
    • Mesos Marathon: Marathon is one of the frameworks to run containers at scale on Apache Mesos.
    • Amazon ECS: Amazon EC2 Container Service (ECS) is a hosted service provided by AWS to run Docker containers at scale on its infrastructrue.
    • Hashicorp Nomad: Nomad is the container orchestrator provided by HashiCorp.
