通常情况下,人们只能使用普通旧数据作为 Kubernetes 中最小的操作单元。他们可以创建一个普通旧数据,但不能控制普通旧数据中的容器,也不能通过 Kubernetes 应用程序接口在某些节点上提取图像。这是因为 Kubernetes 没有提供操作运行时的应用程序接口,比如 Containerd 或 Docker。据我所知,一些公司在他们的集群中入侵了 Kubelet 的代码,以便他们可以对容器做更多的事情。然而,为运行时扩展操作确实是一种错误的方法,因为它不利于开源和社区的合作。现在,云原生计算基金会沙箱项目之一 OpenKruise 提供了高级功能,可以在每个原始 Kubernetes 集群中操作容器运行时。它支持通过 CRD 进行大规模图像预下载和容器重启,因此用户只需应用 CR 另一种标记语言即可完成这些工作。在本次演讲中,我们将介绍 OpenKruise 中功能的用法,以及它如何与 Kubelet 和 CRI 合作。

Usually, people could only use Pod as the minimal operating unit in Kubernetes. They can create a Pod, but they can not control the containers in Pod nor pull images on some nodes via Kubernetes API. It is because Kubernetes does not provide API for operating the Runtime, such as Containerd or Docker. As I know, some companies have hacked the code of Kubelet in their clusters, so that they can do more things to the containers. However, it is really a wrong way to extend operations for Runtime for it goes against the opensource and cooperation of community. Now that OpenKruise, one of the CNCF Sandbox projects, has provided high-level abilities that can operate the container runtime in every original Kubernetes cluster. It supports large-scale image pre-download and container restart by CRD, so that users can do these things by simply applying a CR YAML. In this talk, we would like to introduce usage of the features in OpenKruise and how does it cooperate with Kubelet and CRI.
