Review logs Check the Traefik controller logs for errors. Run diagnostics Use the Ingress status report to identify issues. Roll back if needed If you encounter critical issues, roll back to Ingress-NGINX by disabling the Traefik ALB and re-enabling the Ingress-NGINX ALB with its original version. Plan to resolve the issues and migrate. Explore the capabilities of IBM Cloud Kubernetes Service and discover the tools to automate, isolate, secure, manage, and monitor your workloads. IBM Cloud Kubernetes Service is moving away from Ingress-NGINX because the upstream project is retired. Traefik is the Ingress controller that IBM supports going forward. Ingress is a Kubernetes service discovery method that exposes the services in your cluster to the public or private network by forwarding requests to your apps and balancing network traffic workloads. Ingress manages external access to your services based on a set of routing rules that you configure and that are applied to all incoming traffic. The portable public subnet for your cluster on IBM Cloud provides 5 usable IP addresses. 1 portable public IP address is used by the default public Ingress ALB. The remaining 4 portable public IP addresses can be used to expose single apps to the internet by creating public Network Load Balancer (NLB) services. To list all of the portable IP addresses in the Kubernetes cluster, both used and. Manager service access role in all namespaces Review existing Ingress resources for Ingress-NGINX specific annotations or configurations. Review the documentation on the key differences between the two Ingress controllers. Plan your migration strategy based on workload requirements, downtime tolerance, and resource availability. The ALB is based on the opensource Kubernetes Ingress-Nginx project and the IBM Cloud Kubernetes Service ALB versions align with the community releases. The IKS ALB versions are in the format major _ minor _ patch _ build _iks, with the build number specific to the IKS release process. The IBM build number indicates the most recent build of the Traefik release that IBM Cloud Kubernetes Service released. For example, the version 3.7.1_345548836_iks indicates the most recent build of the 3.7.1 Traefik version. : alb-version-choose site.data.keyword.containerlong_notm supports only the Kubernetes Ingress image and the Traefik image for the Ingress application load balancers (ALBs) in your cluster. The Kubernetes Ingress image is built on the community Kubernetes project's implementation of the NGINX Ingress controller. The Traefik image is built on the community Traefik project's. Traefik is delivered as a separate Ingress Controller version, and until the sunset of Ingress-NGINX both controller versions will be available (even after Ingress-NGINX is marked as deprecated in September). During this time we highly encourage our users to make the move to ensure seamless operations.
