A collection of out-of-tree scheduler plugins for Kubernetes built on the scheduler framework, including capacity scheduling, coscheduling (gang scheduling), load-aware Trimaran, and network/topology-aware scheduling. Plugins can be vendored as Go libraries or deployed out-of-the-box via pre-built container images and Helm charts.

Use cases

• schedule groups of pods together with gang scheduling
• make Kubernetes scheduling load-aware instead of purely requests-based
• schedule pods with network or NUMA topology awareness
• customize pod preemption behavior in Kubernetes
• extend kube-scheduler with custom scheduling logic
• manage cluster capacity with elastic quota scheduling

When to choose

• you need scheduling behaviors kube-scheduler's built-in plugins don't provide, like gang scheduling or load-aware placement
• you want production-proven plugins exercised at large companies
• you prefer deploying via official images or Helm charts
• you want to vendor scheduler plugins as a Go SDK in your own scheduler build

When to avoid

• your scheduling needs are fully met by default kube-scheduler configuration and profiles
• you're not running Kubernetes
• you only need the sample plugins, which are explicitly not production-ready
• you want a fully managed scheduling solution without operating custom scheduler images
