8-9: Add session affinity configuration to resolve login issues.To fix the login redirection issue, the deployment needs to work in conjunction with session affinity settings. While session affinity is typically configured in the Service resource, the deployment should be updated to support this pattern.
Add the following annotations to the pod template metadata to ensure proper session handling:
template: metadata: labels: app: bankapp + annotations: + # Ensure cookie-based session stickiness is respected + nginx.ingress.kubernetes.io/affinity: "cookie" + nginx.ingress.kubernetes.io/session-cookie-name: "BANKAPP_SESSION" + nginx.ingress.kubernetes.io/session-cookie-expires: "172800" + nginx.ingress.kubernetes.io/session-cookie-max-age: "172800"

32-49: Consider adding health checks for better reliability.The deployment lacks liveness and readiness probes, which are crucial for maintaining high availability and proper pod lifecycle management.
Add health check probes:
env: - name: SPRING_DATASOURCE_URL valueFrom: configMapKeyRef: name: bankapp-config key: SPRING_DATASOURCE_URL + livenessProbe: + httpGet: + path: /actuator/health/liveness + port: 8080 + initialDelaySeconds: 60 + periodSeconds: 10 + readinessProbe: + httpGet: + path: /actuator/health/readiness + port: 8080 + initialDelaySeconds: 30 + periodSeconds: 5

23-31: Enhance production readiness with session storage configuration.For production-grade deployments, the PR objectives recommend combining session affinity with robust session storage. The current configuration lacks persistent storage for session data.
Consider adding:
- A persistent volume for session storage
- Redis/Memcached for distributed session management
- Appropriate volume mounts and environment variables
Example configuration:
resources: limits: memory: "1Gi" cpu: "500m" requests: memory: "512Mi" cpu: "250m" + volumeMounts: + - name: session-store + mountPath: /app/sessions + volumes: + - name: session-store + persistentVolumeClaim: + claimName: session-store-pvcsrc/main/java/com/example/bankapp/config/WebConfig.java (1)
12-15: Consider environment-specific CORS configuration.While the CORS configuration is correct for the production environment, consider making the allowed origin configurable through environment variables or properties to support different environments (dev, staging, prod).
registry.addMapping("/**") - .allowedOrigins("https://bankapp.snehaws.com") // Your frontend domain + .allowedOrigins(environment.getProperty("app.cors.allowed-origins")) .allowedMethods("GET", "POST", "PUT", "DELETE", "OPTIONS") .allowCredentials(true);Add to application.properties:
app.cors.allowed-origins=https://bankapp.snehaws.comkubernetes/bankapp-ingress.yml (1)
Line range hint
22-35: Consider separating frontend and backend ingress rules.The current configuration mixes paths for both the main application and nginx service. Consider splitting these into separate Ingress resources for better maintainability and security isolation.
Would you like me to provide an example of how to split these configurations?

💡 Codebase verification
Fix duplicate CORS configuration files and externalize properties
The review comment's suggestion is valid, and additional issues were found:
- Duplicate configuration files exist:
webconfig.javaandWebConfig.javawith identical content - CORS origin is hardcoded without environment-specific configuration
Action items:
- Remove one of the duplicate files (prefer keeping
WebConfig.javafollowing Java naming conventions) - Add CORS properties to
application.properties:
app.cors.allowed-origin=https://bankapp.snehaws.com- Update the configuration to use the property:
@Value("${app.cors.allowed-origin}")
private String allowedOrigin;
@Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedOrigins(allowedOrigin)
.allowedMethods("GET", "POST", "PUT", "DELETE", "OPTIONS")
.allowCredentials(true);
}🔗 Analysis chain
Review security implications of CORS with credentials
While the CORS configuration is necessary, enabling allowCredentials with a specific origin requires careful consideration:
- Ensure the frontend domain is correctly specified
- Consider making the allowed origin configurable via environment variables
- Verify that sensitive endpoints are properly secured as CORS with credentials can expose them to CSRF attacks
Consider extracting the origin URL to a configuration property:
- .allowedOrigins("https://bankapp.snehaws.com")
+ @Value("${app.cors.allowed-origin}")
+ private String allowedOrigin;
+ // ...
+ .allowedOrigins(allowedOrigin)🏁 Scripts executed

Use explicit versioning for container images.
The current image tag bankappv3 is not immutable and could lead to inconsistency across replicas or during rollbacks.

Reolved
By enabling session affinity using cookie-based stickiness, the ingress ensured consistent routing of requests for logged-in users to the same pod. This resolved the issue of repeated redirection to the login page, providing a seamless user experience. For production-grade deployments, consider combining session affinity with robust session storage mechanisms to ensure high availability and fault tolerance.
