Kubernetes Resource & Scheduling Planner

Calculate requests across app, init and restartable sidecar containers, apply LimitRange defaults, filter Nodes, place replicas, and forecast ResourceQuota usage.

Workload, Node, and quota snapshots stay in this browser
The tool never contacts a cluster, runs kubectl, or mutates workloads; anonymous events contain no cluster or resource identifiers.

Resource and scheduling snapshot

Supports Pods/workloads, Nodes, LimitRange, and ResourceQuota; up to 10 MiB, 5,000 objects, and 1,000 simulated replicas.

Load the sample or paste Nodes, workloads, existing Pods, LimitRange, and ResourceQuota snapshots.

About Kubernetes Resource & Scheduling Planner

Estimate effective Pod requests, node fit and quota impact. Calculate requests across app, init and restartable sidecar containers, apply LimitRange defaults, filter Nodes, place replicas, and forecast ResourceQuota usage. The core workflow is designed to run in your current browser.

Key capabilities

  • Model regular containers, init peaks, restartable sidecars and Pod overhead
  • Check Ready state, cordons, selectors, required affinity, taints and capacity
  • Greedily place each planned replica with deterministic reasons
  • Combine current quota usage with the planned workload request

Useful for

  • Estimate whether current Nodes can host a rollout
  • Reproduce common FailedScheduling reasons from a snapshot
  • Review requests, QoS, LimitRange and quota impact before deployment
