What You Can Do
You can generate complete, production-ready Kubernetes manifests from application requirements or audit existing YAML configurations for security vulnerabilities, resource efficiency, and reliability gaps. The skill applies industry best practices including CPU/memory limits, liveness and readiness probes, graceful rollout strategies, and least-privilege RBAC policies—eliminating common deployment pitfalls and accelerating your path to secure, scalable containerized applications.
Features
Creates YAML with replicas, rolling update strategy, and pod disruption budgets configured for zero-downtime deployments
Generates liveness and readiness probes (HTTP, TCP, exec) tailored to your application startup time and health endpoints
Automatically sets CPU/memory requests and limits based on application tier to prevent cluster overallocation and eviction
Creates ServiceAccounts, Roles, and RoleBindings implementing least-privilege access control for your workloads
Generates ClusterIP, NodePort, and LoadBalancer Services plus Ingress rules with TLS configuration
Structures environment variables and configuration files for safe, auditable configuration management
Reviews existing YAML for missing resource limits, probe gaps, RBAC violations, and production readiness issues with specific remediation steps
Recommends maxSurge, maxUnavailable, and minReadySeconds settings based on your availability requirements
Example Output
Example 1: Generate Deployment with Health Checks
Input: Node.js API running on port 3000 with /health endpoint
Output:
apiVersion: apps/v1
kind: Deployment
metadata:
name: api-service
namespace: production
spec:
replicas: 3
strategy:
type: RollingUpdate
rollingUpdate:
maxSurge: 1
maxUnavailable: 0
template:
spec:
containers:
- name: api
image: myrepo/api:v1.2.0
ports:
- containerPort: 3000
livenessProbe:
httpGet:
path: /health
port: 3000
initialDelaySeconds: 30
periodSeconds: 10
readinessProbe:
httpGet:
path: /ready
port: 3000
initialDelaySeconds: 5
periodSeconds: 5
resources:
requests:
cpu: 100m
memory: 256Mi
limits:
cpu: 500m
memory: 512Mi
Example 2: Audit Existing Manifest
Input: User pastes production Deployment without resource limits
Output: ✗ Missing resource requests/limits — Pod may be evicted. Add requests: {cpu: 100m, memory: 256Mi} and limits: {cpu: 500m, memory: 512Mi} ✗ No liveness probe — Container restarts will be delayed. Add httpGet probe to /health endpoint with initialDelaySeconds: 30 ✓ RBAC: ServiceAccount configured — Least-privilege access enforced ✓ Rolling update strategy — maxUnavailable: 0 ensures zero-downtime deployments
