using a group name results in duplicate health checks #3018

Closed williamcodes closed 1 year ago

williamcodes commented 1 year ago

Describe the bug When using alb.ingress.kubernetes.io/group.name and alb.ingress.kubernetes.io/healthcheck-path for services with the same name but in different namespaces, the health checks get duplicated across all services. So having 40 namespaces means you get 40x the healthchecks. This is enough to overwhelm some pods.


alb.ingress.kubernetes.io/group.name

Steps to reproduce

  1. Create multiple services with the same name but in different namespaces
  2. Set up ingresses for them with a shared group name
  3. Set up health checks for them as well

Expected outcome A concise description of what you expected to happen.

Expect routing to send only one health check to each service.
