In Kubernetes many controllers want to know IP addresses of all pods associated with a service. Because we have many many pods in Kubernetes and it's expensive asking the API server to go and find the selector. Kubernetes group them together in an object called Endpoints so that instead of ...
Docker:这个标准存在了很长一段时间,但从未真正用于容器编排。Docker作为Kubernetes运行时的使用已经被弃用,并将在Kubernetes 1.23中移除。Kubernetes有一篇很棒的博客文章,回答了关于这个问题的所有问题。 使用containerd创建容器要比使用Docker简单得多 containerd和CRI-O的想法非常简单:提供一个只包含运行容器绝对必要的运行...

下面是一个使用Docker的例子: 为了允许使用其他容器运行时而不是Docker, Kubernetes在2016年引入了容器运行时接口(CRI)。 containerd:Containerd是一个运行容器的轻量级、高性能实现。可以说是目前最流行的容器运行时。Kubernetes即服务产品的所有主要云提供商都使用它。
Container runtime engines, such as Docker’s runC, leverage OS-level virtualization capabilities offered from the kernel to create isolated spaces called “containers.” This virtualization makes it possible to efficiently deploy and securely run a container independently of the hosting infrastructure. Be...

阅读微服务:容器和编排白皮书(https://www.mongodb.com/collateral/microservices-containers-and-orchestration-explained)。 编排工具管理着多个容器如何创建、升级和高可用。编排同样管理着容器如何连接,并利用多个微服务容器创建稳定的应用服务。 丰富的功能、简单的工具、强大的API让容器和编排得到DevOps团队的青睐。DevOps...
