OpenKruise is an extended component suite for Kubernetes, which mainly focuses on automated management of large-scale applications, such as deployment, upgrade, ops, and availability protection. Most features provided by OpenKruise are built primarily based on CRD extensions. They can work in pure Kubernetes clusters without any other dependencies. Kubernetes itself has already provided some features for application deployment and management, such as some basic Workloads. However, it is far from enough to deploy and manage lots of applications in large-scale production clusters. OpenKruise can be easily installed in any Kubernetes cluster. It makes up for defects of Kubernetes, including but not limited to application deployment, upgrade, protection, and operations.
