The Kubernetes Ingress resource connects external requests to services within Kubernetes clusters. While developers use Ingress to route requests, its basic functionality can be limiting, using only path and host criteria. The reliance on vendor-specific Ingress controllers complicates the routing logic and maintenance, especially when annotations differ across implementations. The Kubernetes Gateway API was introduced to standardize and enhance Ingress capabilities, allowing for the implementation of complex rules without additional annotations, thus facilitating easier collaboration among teams and simpler maintenance across services.
The Gateway API addresses the lack of standardization with Ingress, providing sophisticated functionality without needing extra vendor-specific annotations, simplifying maintenance for multiple teams.
Native Ingress in Kubernetes has limited routing capabilities; it only uses the specified host and path to grant access to services, which can be insufficient.
Multiple teams often find it challenging to work on a single Ingress resource due to proprietary annotations that can complicate configurations and maintenance.
The Kubernetes Gateway API represents a 'next-generation Ingress' solution, offering enhanced functionality and streamlined processes for developers and DevOps teams.
