kube-fledged is a Kubernetes operator that creates and manages a cache of container images directly on cluster worker nodes. By pre-pulling specified images onto chosen nodes, it enables application pods to start almost instantly without waiting for registry pulls.

Use cases

• pre-pull container images onto kubernetes worker nodes
• speed up pod startup times in a kubernetes cluster
• reduce image pull latency when scaling applications rapidly
• cache images for real-time data processing workloads that need fast scale-out
• manage the lifecycle of a node-level image cache via CRUD APIs
• avoid registry rate limits and network delays during pod scheduling

When to choose

• your kubernetes applications need near-instant pod startup or fast autoscaling
• you want to pre-pull images onto specific worker nodes declaratively
• image pull times from a remote registry are a bottleneck for your workloads
• you need a kubernetes-native add-on with Helm installation and CRUD APIs for image caching

When to avoid

• your cluster already uses local registries or node image preloading via DaemonSets and that suffices
• you run a small cluster where image pull latency is not a concern
• you need general-purpose image building or registry mirroring rather than caching
• you require a fully managed cloud service rather than a self-managed operator
