Informer timed out on 60s

[sichenzhao]

What happened:

• On testing the latest updates on master, I encountered 60s time out
  https://github.com/kubernetes-sigs/external-dns/blame/master/source/informers/informers.go#L29

• Error message I got: {"level":"fatal","msg":"failed to sync *v1.EndpointSlice: context deadline exceeded with timeout 1m0s","time":"2025-07-04T19:35:16Z"}

What you expected to happen:

• We probably should have a configurable timeout for informer to run? I can make the change if needed, to make it configurable.

How to reproduce it (as minimally and precisely as possible):

• Build latest master, run it in k8s with istio virtual services/gateways which could cause informer to run more than 60s

Anything else we need to know?:

Environment:

• External-DNS version (use external-dns --version): latest master
• DNS provider:
• Others:

Yeah. You could try. This is a PR where things were moved to specific folder only #5466 (comment). There is already a flag, but this needs to be applied to all sources. This needs to be implemented in a way to easy extend things, some common interface or smth.
