Load trigger: "load k8s-design-validation skill" > DORA: Cap 1 (AI Policy) Token cost: Low

Purpose

Validate Kubernetes-related design decisions.

Responsibilities

• Validate resource requirements in design
• Validate deployment patterns
• Validate network design
• Validate secret usage approach

Inputs

• design.md
• architecture.json

Outputs

• k8s-design.json

Validation Rules

Resource Design

• CPU requests/limits specified per component
• Memory requests/limits specified per component
• Storage requirements specified (if applicable)
• Horizontal scaling approach defined

Deployment Patterns

• Deployment strategy chosen (RollingUpdate, Recreate)
• Replica count specified
• Pod disruption budgets defined (if needed)
• Init containers defined (if needed)

Network Design

• Service types defined (ClusterIP, NodePort, LoadBalancer)
• Ingress rules defined
• Network policies defined
• DNS strategy defined

Secret Management

• Secret storage approach chosen (native, Vault, ExternalSecrets)
• Secret rotation strategy defined
• Secret access pattern defined
• Encryption at rest approach defined

Storage Design

• Persistent volume claims defined (if needed)
• Storage classes specified
• Backup strategy defined (if needed)

Design Patterns

Pattern	Use When
Deployment	Stateless workloads
StatefulSet	Stateful workloads (databases, queues)
DaemonSet	Node-level agents (logging, monitoring)
Job/CronJob	Batch or scheduled workloads
