Kubernetes Gateway API Template
This Kubernetes template deploys a scalable, secure, and modern application architecture utilizing the Gateway APIthe next-generation standard for service networking.
Designed for organizations moving beyond the limitations of standard Ingress, this manifest provides a modular, role-oriented framework that separates infrastructure management from application development.
It eliminates common networking pitfalls such as annotation sprawl, manual SSL management, and rigid traffic routing.
What This Template Creates for Your Kubernetes Cluster
This stack provides a complete "browser-to-pod" flow, integrating advanced traffic management with automated security and scaling.
1. Next-Gen Traffic Infrastructure
-
GatewayClass Defines the infrastructure provider (e.g., Envoy or Istio) and establishes the organizational standard for load balancing
-
Gateway (prod-gateway) Acts as the entry point for all external traffic, managing public IP addresses and entry ports (HTTPS/443)
-
HTTPRoute (main-app-route) Provides sophisticated L7 routing logic, mapping hostnames and URL paths to internal services
2. Automated Security & Identity
-
Cert-Manager Integration Automatically provisions and renews SSL/TLS certificates via Let's Encrypt using the
ClusterIssuer -
app-tls-secret A dynamically managed secret created by Cert-Manager to secure the "Front Door" with high-grade encryption
-
app-secrets A secure, opaque storage for sensitive application data like database passwords and API keys, keeping them out of your source code
3. Decoupled Configuration & Discovery
-
ConfigMap (app-config) Centralizes non-sensitive environment variables (log levels, API URLs), allowing configuration changes without rebuilding container images
-
Headless-Ready Service Bridges the gap between the Gateway and the backend, providing stable DNS names for routing
