Hook called twice for same event and same resource

[mloskot]

I have written a simple hook in Python and configured it to subscribe monitor deletion of certain secrets:

CONFIG = {
    "configVersion": "v1",
    "kubernetes": [
        {
            "name": "Monitor secrets apikey-monitor=enabled label",
            "allowFailure": True,
            "apiVersion": "v1",
            "kind": "Secret",
            "executeHookOnEvent": ["Deleted"],
            "labelSelector": {
                "matchLabels": {"apikey-monitor": "enabled"},
            },
            "namespace": {
                "labelSelector": {
                    "matchLabels": {"apikey-monitor": "enabled"},
                },
            },
        },
    ],
}

My hook script only runs its logic if watchEvent successfully tests for Deleted.

When I delete a single secret with the monitored label from my cluster, then I am observing in the operator logs that my hook is called twice:

{ "level":"info","logger":"shell-operator.hook-manager.hook.executor","msg":"Deleting secret default/myapikey",
  "binding":"Monitor secrets apikey-monitor=enabled label","event":"kubernetes","hook":"01-apikey.py",
  "output":"stdout","queue":"main","task":"HookRun","time":"2025-07-30T14:47:43Z"}
{ "level":"info","logger":"shell-operator.hook-manager.hook.executor","msg":"Deleting secret default/myapikey",
  "binding":"Monitor secrets apikey-monitor=enabled label","event":"kubernetes","hook":"01-apikey.py",
  "output":"stdout","queue":"main","task":"HookRun","time":"2025-07-30T14:47:43Z"}

What could be the reason for the double invocation?

I've read the docs HOOKS.md and search the archives but I cannot find an explanation of the duplicate invocation.

Please, forget this thread and forgive the noise.

The issue was due to a silly bug in my Python code - it's been a long time since I wrote any Python - where I missed the break in for/else 🤦‍♂️
