## What I do - Create Kubernetes manifests (Deployments, Services, ConfigMaps, etc.) - Configure resources and limits properly - Implement health checks (liveness, readiness probes) - Manage secrets and configmaps - Set up autoscaling (HPA, VPA) - Configure networking (Ingress, NetworkPolicies) - Use Helm charts for templating ## When to use me When creating Kubernetes configurations or deploying to K8s clusters. ## Deployment with Probes ```yaml apiVersion: apps/v1 kind: Deployment metadata: name: api-server labels: app: api-server version: v1 spec: replicas: 3 selector: matchLabels: app: api-server strategy: type: RollingUpdate rollingUpdate: maxSurge: 25% maxUnavailable: 0 template: metadata: labels: app: api-server version: v1 spec: serviceAccountName: api-server securityContext: runAsNonRoot: true runAsUser: 1000 fsGroup: 1000 containers: - name: api-server image: registry.example.com/api-server:v1.2.3 ports: - containerPort: 8080 name: http envFrom: - configMapRef: name: api-config - secretRef: name: api-secrets resources: requests: cpu: 100m memory: 128Mi limits: cpu: 500m memory: 512Mi livenessProbe: httpGet: path: /health/live port: 8080 initialDelaySeconds: 10 periodSeconds: 10 failureThreshold: 3 readinessProbe: httpGet: path: /health/ready port: 8080 initialDelaySeconds: 5 periodSeconds: 5 failureThreshold: 3 startupProbe: httpGet: path: /health/startup port: 8080 failureThreshold: 30 periodSeconds: 10 --- apiVersion: v1 kind: Service metadata: name: api-server spec: selector: app: api-server ports: - port: 80 targetPort: 8080 protocol: TCP name: http type: ClusterIP ``` ## ConfigMap and Secrets ```yaml apiVersion: v1 kind: ConfigMap metadata: name: api-config data: DATABASE_URL: "postgres://..." REDIS_URL: "redis://..." LOG_LEVEL: "info" API_VERSION: "v1" --- apiVersion: v1 kind: Secret metadata: name: api-secrets type: Opaque stringData: DATABASE_PASSWORD: "your-password" API_KEY: "your-api-key" ``` ## Horizontal Pod Autoscaler ```yaml apiVersion: autoscaling/v2 kind: HorizontalPodAutoscaler metadata: name: api-server-hpa spec: scaleTargetRef: apiVersion: apps/v1 kind: Deployment name: api-server minReplicas: 3 maxReplicas: 50 metrics: - type: Resource resource: name: cpu target: type: Utilization averageUtilization: 70 - type: Resource resource: name: memory target: type: Utilization averageUtilization: 80 behavior: scaleUp: stabilizationWindowSeconds: 60 policies: - type: Percent value: 100 periodSeconds: 60 scaleDown: stabilizationWindowSeconds: 300 policies: - type: Percent value: 10 periodSeconds: 60 ``` ## Ingress ```yaml apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: api-ingress annotations: nginx.ingress.kubernetes.io/ssl-redirect: "true" nginx.ingress.kubernetes.io/proxy-body-size: "10m" nginx.ingress.kubernetes.io/proxy-read-timeout: "300" nginx.ingress.kubernetes.io/proxy-send-timeout: "300" spec: ingressClassName: nginx tls: - hosts: - api.example.com secretName: api-tls rules: - host: api.example.com http: paths: - path: /api pathType: Prefix backend: service: name: api-server port: number: 80 ``` ## Commands ```bash # Apply and manage kubectl apply -f manifests/ kubectl rollout status deployment/api-server kubectl rollout undo deployment/api-server # Debug kubectl get pods -l app=api-server kubectl logs -f deployment/api-server kubectl describe pod <pod-name> kubectl exec -it <pod-name> -- /bin/bash # Scale and update kubectl scale deployment/api-server --replicas=10 kubectl set image deployment/api-server api-server=registry.example.com/api-server:v1.2.4 ```
