Thanks to all our contributors! 😊

Action required

🚨 🚨 🚨

We’ve added new fields to the IngressClassParams CRD. Please apply the latest CRD definitions: kubectl apply -k "github.com/aws/eks-charts/stable/aws-load-balancer-controller/crds?ref=master"

What’s new

• Improved Prometheus metrics!
  • Checkout the new Prometheus metrics. Their documentation can be found here. https://kubernetes-sigs.github.io/aws-load-balancer-controller/v2.13/guide/metrics/prometheus. We hope this improves the ability to debug issues using the LBC and monitoring general trends. Please submit an issue if you think we missed an important metric to collect.
• Added support for ALB as a target of NLB to Service objects.
  • We are thrilled to add support for this highly requested, popular NLB / ALB feature. https://aws.amazon.com/blogs/networking-and-content-delivery/application-load-balancer-type-target-group-for-network-load-balancer/
  • Check out the new annotations in the https://kubernetes-sigs.github.io/aws-load-balancer-controller/v2.13/guide/service/nlb/to get started.
• LBC now supports RAM shared VPCs
  • In the v2.12.0 release, LBC added support for cross account Target Groups. However, we missed some critical functionality to support Target Groups using RAM shared VPCs.
  • Using https://kubernetes-sigs.github.io/aws-load-balancer-controller/v2.13/guide/targetgroupbinding/targetgroupbinding/#assumerole should seamlessly work for peered and RAM shared VPCs.
• LBC now supports TCP_UDP type Listeners and TargetGroups.
  • TCP_UDP is a popular listener type for AWS NLB, which allows serving both TCP and UDP from the same port. We have backfilled this feature into the LBC.
  • You can enable this feature by specifying a service with TCP and UDP protocols on the same port.
  • In order to enable the feature, please enable the LBC feature flag EnableTCPUDPListener or specify individual services to enable the feature by using the annotation service.beta.kubernetes.io/aws-load-balancer-enable-tcp-udp-listener
• The LBC now supports a very basic Gateway API implementation
  • We have implemented a basic Gateway for both ALB and NLB.
  • See the documentation here https://kubernetes-sigs.github.io/aws-load-balancer-controller/v2.13/guide/gateway/gateway/

Enhancement and Fixes

• Added more customization options (TargetType, PrefixListsIDs) to the IngressClassParams CRD.
• Allow for setting PPv2 header at per target group level.
• Refactored Subnet discovery to make LB creation easier.
• Updated to Go 1.24.2 and AL2023 base image to resolve security vulnerabilities.
• Lots of documentation and logging fixes!
