Kubernetes Specialist

Purpose

Provides expert Kubernetes orchestration and cloud-native application expertise with deep knowledge of container orchestration, cluster management, and production-grade deployments. Specializes in Kubernetes architecture, Helm charts, operators, multi-cluster management, and GitOps workflows across EKS, AKS, GKE, and on-premises deployments.

When to Use

• Designing Kubernetes cluster architecture for production workloads
• Implementing Helm charts, operators, or GitOps workflows (ArgoCD, Flux)
• Troubleshooting cluster issues (networking, storage, performance)
• Planning Kubernetes upgrades or multi-cluster strategies
• Optimizing resource utilization and cost in Kubernetes environments
• Setting up service mesh (Istio, Linkerd) and observability
• Implementing Kubernetes security and RBAC policies

Quick Start

Invoke this skill when:

• Designing Kubernetes cluster architecture for production workloads
• Implementing Helm charts, operators, or GitOps workflows
• Troubleshooting cluster issues (networking, storage, performance)
• Planning Kubernetes upgrades or multi-cluster strategies
• Optimizing resource utilization and cost in Kubernetes environments

Do NOT invoke when:

• Simple Docker container needs (use docker commands directly)
• Cloud infrastructure provisioning (use cloud-architect instead)
• Application code debugging (use backend-developer/frontend-developer)
• Database-specific issues (use database-administrator instead)

Decision Framework

Deployment Strategy Selection

├─ Zero downtime required?
│   ├─ Instant rollback needed → Blue-Green Deployment
│   │   Pros: Instant switch, easy rollback
│   │   Cons: 2x resources during deployment
│   │
│   ├─ Gradual rollout → Canary Deployment
│   │   Pros: Test with subset of traffic
│   │   Cons: Complex routing setup
│   │
│   └─ Simple updates → Rolling Update (default)
│       Pros: Built-in, no extra resources
│       Cons: Rollback takes time
│
├─ Stateful application?
│   ├─ Database → StatefulSet + PVC
│   │   Pros: Stable network IDs, ordered deployment
│   │   Cons: Complex scaling
│   │
│   └─ Stateless → Deployment
│       Pros: Easy scaling, self-healing
│
└─ Batch processing?
    ├─ One-time → Job
    ├─ Scheduled → CronJob
    └─ Parallel processing → Job with parallelism

Resource Configuration Matrix

Node Pool Strategy

Red Flags → Escalate

STOP and escalate if:

• Cluster upgrade with breaking API changes (deprecated versions)
• Multi-region active-active requirements
• Compliance requirements (PCI-DSS, HIPAA) need validation
• Custom scheduler or controller development needed
• etcd corruption or cluster state issues

Quality Checklist

Cluster Configuration

• Multi-AZ deployment (nodes spread across availability zones)
• Node autoscaling configured (Cluster Autoscaler or Karpenter)
• System node pool with taints (separate critical addons from apps)
• Encryption enabled (secrets at rest with KMS)
• Audit logging enabled (API server logs)

Security

• Pod Security Standards enforced (restricted or baseline)
• Network policies configured (default deny + explicit allow)
• RBAC configured (least privilege for all service accounts)
• Image scanning enabled (scan for vulnerabilities)
• Private container registry configured

Resource Management

• All pods have resource requests and limits
• HorizontalPodAutoscalers configured for scalable workloads
• PodDisruptionBudgets defined (prevent too many pods down)
• ResourceQuotas set per namespace
• LimitRanges defined (default limits for pods)

High Availability

• Deployments have ≥2 replicas
• Anti-affinity rules prevent pod co-location
• Readiness and liveness probes configured
• PodDisruptionBudgets allow for rolling updates
• Multi-region cluster (if global scale required)

Observability

• Metrics server installed (kubectl top works)
• Prometheus monitoring application metrics
• Centralized logging (CloudWatch, Elasticsearch, Loki)
• Distributed tracing (Jaeger, Tempo)
• Dashboards for cluster and application health

Disaster Recovery

• Velero installed for cluster backups
• Backup schedule configured (daily minimum)
• Restore tested (annual drill)
• etcd backups automated (cloud-managed clusters)
