## What it is
OpenKruise is a CNCF incubating suite of Kubernetes controllers and CRDs that extends core workload management with advanced capabilities like in-place updates, configurable scaling/upgrade strategies, and sidecar injection. It provides advanced workloads (CloneSet, Advanced StatefulSet/DaemonSet, BroadcastJob), day-2 operations tooling, and high-availability protection for large-scale applications.

## Use cases
- update container images in-place without recreating pods
- manage sidecar injection and sidecar in-place upgrades
- run jobs across all or selected nodes in a cluster
- control scale-in and upgrade ordering for stateful apps
- protect workloads from cascading deletion and voluntary disruptions
- prewarm container images on nodes before deployment
- progressive rollout delivery for native Kubernetes workloads

## When to choose
- you run large-scale applications on Kubernetes and outgrow built-in Deployment/StatefulSet features
- you need faster, lower-disruption updates via in-place container restarts
- you want declarative sidecar lifecycle management
- you need fine-grained control over scaling, upgrade, and job distribution strategies

## When to avoid
- you only need basic Deployments and StatefulSets with no advanced rollout needs
- you run very old Kubernetes clusters below the supported version range
- you want a zero-extra-component cluster and cannot tolerate an additional controller set
- you rely on dockershim, which is no longer supported
