Kubernetes Orchestration

Deploy and manage containerized applications at scale with Kubernetes orchestration, services, and production patterns.

Core Resources

        env:
        - name: DATABASE_URL

        resources:
          requests:
            memory: "128Mi"
            cpu: "100m"
          limits:
            memory: "256Mi"
            cpu: "200m"
        livenessProbe:
          httpGet:
            path: /health
            port: 3000
          initialDelaySeconds: 30
          periodSeconds: 10

Service

CopyapiVersion: v1
kind: Service

    app: myapp
  ports:
  - protocol: TCP
    port: 80
    targetPort: 3000
  type: LoadBalancer

Ingress

CopyapiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: myapp-ingress
  annotations:
    cert-manager.io/cluster-issuer: letsencrypt-prod
spec:
  tls:
  - hosts:
    - myapp.example.com
    secretName: myapp-tls

      - path: /
        pathType: Prefix
        backend:
          service:
            name: myapp-service
            port:
              number: 80

ConfigMap

CopyapiVersion: v1
kind: ConfigMap
metadata:
  name: myapp-config
data:
  app.env: production
  log.level: info

Best Practices

1. Use namespaces for organization
2. Implement resource limits
3. Use liveness and readiness probes
4. Manage secrets properly
5. Use StatefulSets for stateful apps
6. Implement network policies
7. Use Helm for packaging
8. Monitor with Prometheus
