OpenKruise is a set of standard extensions for Kubernetes. It can be used with Kubernetes to manage application pods, sidecar containers, and image distribution in an efficient manner. This topic introduces OpenKruise and describes the usage notes and release notes for OpenKruise.
Introduction
OpenKruise is an open source automation engine that Alibaba Cloud provides for cloud-native applications. It is used as a deployment base to migrate the business of Alibaba Group to the cloud. OpenKruise has joined the Cloud Native Computing Foundation (CNCF) Sandbox project. OpenKruise contains a variety of custom workloads. You can use the workloads to deploy and manage stateless applications, stateful applications, sidecar containers, and daemon applications. OpenKruise also supports advanced strategies such as in-place updates, canary releases, stream updates, and priority configuration.
