Providing Secure Ingress into a Multi-Tenanted Cluster Using GatewayAPI

Learn to implement secure ingress solutions for multi-tenant Kubernetes clusters in this 27-minute conference talk from DevConf.CZ 2025. Discover how to leverage GatewayAPI alongside cert-manager, external-dns, and Kong Ingress controller to provide automated HTTP(S)/GRPC(S) ingress access to services using Kubernetes resource manifests. Explore the implementation of RBAC and Hierarchical Namespace controller to enforce required namespace labels, which secure and configure ingress hosts and routes specifically for multi-tenanted cluster environments. Gain practical insights into creating automated, secure ingress configurations that maintain proper isolation and access control across different tenants within a shared Kubernetes infrastructure.
