Kubernetes Deployments That Never Break: Canary Releases Without Extra Controllers
Canary & Blue-Green Deployments Using Gateway API
Most teams think canary and blue-green deployments require a service mesh or a rollout controller.
They don’t.
In this video, I show how to implement canary releases, blue-green deployments, and instant rollback using only Kubernetes Gateway API, no Istio, no Argo Rollouts, no extra control planes.
You’ll see how platform teams:
Deploy a new application version safely
Keep versions isolated using Services
Split traffic gradually using HTTPRoute weights
Roll back instantly by changing routing, not redeploying
The key idea is simple: Deploy first, route later.
Gateway API keeps routing declarative, rollouts controlled, and applications boring exactly how production platforms should work.
