[Kong Ingress Controller Chart] High Load on k8s API with KongUpstreamPolicy and Multiple Ingress Controllers #6270

Open kirillfomichev opened 3 days ago

kirillfomichev commented 3 days ago

Is there an existing issue for this?

Current Behavior

When using UpstreamPolicy in a Kubernetes cluster with two ingress controllers, there is a cyclic configuration overwrite. Both ingress controllers compete for the UpstreamPolicy resource, leading to high load on the k8s API.

Expected Behavior

The ingress controllers should handle the UpstreamPolicy resource without cyclic overwrites, avoiding unnecessary load on the k8s API.

Steps To Reproduce

- Set up a Kubernetes cluster
- Deploy two ingress controllers via helm chart.
- Set up debug-level
- Create a CRD UpstreamPolicy for the ingress controllers.
- Observe the cyclic configuration overwrite and high load on the k8s API.
