☸️ Kubernetes Orchestration for Claude-Code Recursive Execution

Problem Statement

Claude-Code currently runs as a single container in GitHub Actions CI, limiting its scalability, resilience, and ability to handle complex multi-step recursive enhancement workflows. To achieve true cloud-native operation, we need Kubernetes orchestration that enables parallel execution, resource scaling, and sophisticated workflow management.

Vision: Kubernetes-Native Recursive Intelligence

Transform Claude-Code from a simple CI container to a distributed, self-healing system capable of:

• Parallel Processing: Multiple concurrent enhancement streams
• Resource Elasticity: Dynamic scaling based on workload complexity
• State Management: Persistent memory across pod restarts
• Workflow Orchestration: Complex multi-step enhancement pipelines
• Cost Optimization: Intelligent resource allocation and spot instance usage

Technical Architecture

  requests:
    cpu: "1000m"
    memory: "2Gi"
  limits:

Resource Management Strategy

Node Pools & Scaling

# Spot instances for cost optimization
nodePool:
  name: claude-code-spot
  machineType: n1-standard-4
  preemptible: true
  autoscaling:
    minNodeCount: 0
    maxNodeCount: 10
  nodeLabels:
    workload-type: claude-enhancement
  taints:
  - key: claude-code
    value: spot
    effect: NoSchedule

Resource Classes

• Fast Track: < 100m CPU, < 256Mi RAM for simple tasks
• Standard: 500m CPU, 1Gi RAM for typical enhancements
• Intensive: 2000m CPU, 4Gi RAM for complex analysis
• Memory Heavy: 1000m CPU, 8Gi RAM for large codebase processing

Service Mesh Integration
