Updating the Ingress Controller

Kubernetes
1

Hello there,

I am wondering if anyone has had any experience around upgrading the Ingress controller without any downtime. I’m currently running the Controller version 0.9.0 with the Kong version 2.3.3.

If simply take the new YAML files available for the Controller version .1.12 and apply it with all the CRDs etc, does anyone know if it will break anything or are all the upgrades backwards compatible?

Thank you.

There have been a number of breaking changes to the controller since 0.9. You’ll want to review kubernetes-ingress-controller/CHANGELOG.md at main · Kong/kubernetes-ingress-controller · GitHub to see what changes you need to make to your controller configuration and the Kubernetes resources it handles (Ingresses, KongPlugins, etc.).
