CNCF MLOps Pipeline: Complete Data-to-Deployment Reference Architecture

KubeCon Europe 2026 CNCF Projects License

Build a complete end-to-end MLOps pipeline using CNCF graduated and incubating projects

This repository provides a battle-tested reference architecture for production MLOps on Kubernetes, validated across 100,000+ student deployments. It demonstrates the cutting-edge capabilities of CNCF projects including Volcano v1.11 (gang scheduling), OpenCost (GPU cost attribution), KServe v0.15 (LLM serving), HAMi (GPU virtualization), KAITO (simplified LLM deployment), KitOps (model packaging), and in-toto (supply chain security).

Table of Contents

Overview

What This Repository Provides

  • Complete MLOps Pipeline: Six integrated stages from data ingestion to production serving
  • CNCF-Native Architecture: Graduated and incubating projects with minimal vendor lock-in
  • Cost-Aware by Design: GPU cost attribution via OpenCost (Incubating October 2024)
  • Failure-Informed: Common mistakes from 100K+ student deployments documented
  • Production-Ready: Working manifests, not just templates

Why This Architecture?

After teaching AI/ML on Kubernetes to 100,000+ learners, we've identified the patterns that work versus the combinations that fail spectacularly. This repository answers:

  • Which CNCF projects do we need for each MLOps stage?
  • How do these projects integrate without breaking?
  • Why did our GPU bill hit $50K last month?
  • How do we prevent distributed training deadlocks?
  • How do we go from experiment to production safely?

Key Differentiators

  1. Showcases Newest CNCF Capabilities (2024-2025)

    • Volcano v1.11 (March 2025) with network topology-aware scheduling
    • OpenCost (Incubating October 2024) with GPU cost attribution
    • KServe v0.15 (June 2025) with first-class LLM support
    • HAMi (Sandbox August 2024) for GPU virtualization
    • KitOps (Sandbox March 2025) for model packaging as OCI artifacts
    • KAITO (Sandbox October 2024) for simplified LLM deployment
    • in-toto (graduated February 2025) for supply chain attestation

  2. Complete End-to-End Pipeline

    • All six MLOps lifecycle stages with working integration points
    • Production-ready patterns validated across 100K+ implementations

  3. Cost-Aware by Design

    • OpenCost provides real-time GPU cost attribution with NVIDIA DCGM integration
    • HAMi GPU virtualization achieves up to 57% cost savings
    • FinOps visibility from day one, not an afterthought

  3. Registry: Models pushed to Harbor → in-toto attestation → KitOps packaging
  4. Serving: KServe deploys models → KEDA autoscales → Gateway routes traffic
  5. Observe: Prometheus metrics → OpenTelemetry traces → OpenCost GPU costs
  6. Automate: ArgoCD GitOps → Crossplane infrastructure → Argo CI/CD

Deployment Strategies

Canary Deployment (Default)

strategy:
  canary:
    steps:
      - setWeight: 10      # 10% of traffic to new version
      - pause: {duration: 5m}
      - analysis:          # Check metrics
          templates:
            - templateName: success-rate
            - templateName: latency-p95
      - setWeight: 50      # Promote to 50%
      - pause: {duration: 5m}
      - setWeight: 100     # Full rollout

Rollback Triggers:

  • Error rate > 1%
  • P95 latency > 500ms
  • GPU memory errors
  • Failed smoke tests

  • CUDA out of memory (reduce batch size, gradient checkpointing, mixed precision)

Model Serving Issues:

  • InferenceService not ready (image pull failure, model loading failure)

Data Pipeline Issues:

  • Kafka messages not being consumed (scale consumers, increase retention)

Resource Issues:

Networking Issues:

  • Cannot access model endpoint (network policies, Istio misconfiguration)

  • Training extremely slow (data loading bottleneck, not using GPU)

Performance Tuning

Optimization Examples (examples/performance-tuning/optimization-examples.yaml)
