Migration Strategies and Best Practices
Transitioning from Ingress NGINX requires a careful and systematic approach. Start by evaluating your current setup and preparing for any necessary configuration adjustments.
Assessing Current Infrastructure
To begin, verify your existing Ingress NGINX deployment by running:
kubectl get pods --all-namespaces --selector app.kubernetes.io/name=ingress-nginx Make sure you have cluster administrator permissions to execute this command.
Next, document all Ingress resources, including annotations like rewrite-target, canary-by-header, and auth-url, as well as any custom snippets. This step ensures you preserve critical business logic during the migration. Pay close attention to global configurations applied via ConfigMaps, especially those controlling TCP/UDP service exposure, as these settings can impact multiple workloads if not handled correctly.
“The initial and most critical step is to document your existing ingress-nginx setup. This isn’t just about listing your Ingress objects; it’s about noting how they are configured.” – Dave McAllister, NGINX Community Blog
Define clear objectives for the migration. Whether you’re aiming to incorporate advanced security features like a Web Application Firewall (WAF), improve performance metrics such as latency, or simplify configuration management, establish measurable goals. For example, you might aim to reduce p99 latency by 15% or ensure zero downtime during the transition.
Once you have a comprehensive inventory and clear goals, you can move on to planning and testing.
Planning and Testing the Migration
A safe migration strategy involves running both the old and new controllers simultaneously. Deploy the new ingress controller in parallel, using a distinct ingressClassName (e.g., nginx2) and a separate namespace. This setup allows thorough testing without disrupting production traffic.
Systematically convert your existing annotations. Moving from an annotation-heavy configuration to a more structured setup can be challenging, as annotations often lead to complex, manual processes over time. Use official documentation to map your current annotations to their new equivalents, and prepare custom snippets for any features that don’t have direct replacements.
Test all critical components, including Ingress rules, SSL termination, and backend connectivity. If you’re implementing advanced security measures like WAF or mTLS using Policy CRDs, ensure these are tested rigorously to avoid unexpected issues.
Don’t overlook performance validation. Conduct load tests that simulate your expected traffic patterns and latency requirements. Include long-duration tests for persistent connections, such as WebSockets or gRPC, to identify potential stability problems.
Monitor performance metrics using tools like Prometheus and Grafana. Compare latency, error rates, and resource utilization between the old and new controllers during parallel operation. This monitoring helps identify discrepancies before fully committing to the new setup.
For a smoother transition, consider using canary releases to gradually shift live traffic to the new controller. Many modern ingress controllers offer specialized CRDs, such as VirtualServer.Route.Splits, which enable traffic distribution by weight or header-based routing. This approach minimizes risk while providing real-world validation of the new setup.
After completing the migration, document the entire process to meet compliance standards and ensure operational consistency.
US Compliance and Documentation Requirements
For organizations in the United States, thorough documentation is essential for regulatory compliance and operational transparency. Start by building on your infrastructure inventory and carefully record every change made during the migration. This documentation is critical for audits and ensures alignment with regulatory standards, which often require the use of supported and auditable software.
Map your existing ingress-nginx annotations to the new controller configurations, especially when custom server or location snippets are involved. This mapping will be invaluable for compliance reviews and future reference.
Switching to CRD-based configuration models can simplify compliance efforts. Unlike annotation-heavy setups, CRDs provide a Kubernetes-native, structured approach that is easier for compliance teams to review and validate.
Establish clear rollback procedures, including the use of kubectl rollout undo, and maintain backups of your original configurations. When shutting down controller pods, use preStop hooks to allow NGINX to gracefully drain active connections.
Additionally, consider increasing the terminationGracePeriodSeconds setting in your deployment configurations. This adjustment ensures longer-lived connections are properly drained, which is especially important for applications with persistent connections. It also helps maintain compliance with service level agreements during maintenance windows.
When planning and testing your migration, securing remote access is absolutely critical to protect operational data. This isn’t just about technical configurations – it’s about safeguarding sensitive information and meeting compliance standards. If you’re migrating away from Ingress NGINX, using a reliable VPN can help maintain data integrity and keep you aligned with regulatory requirements throughout the process.
