possible api permission issue?

[evillgenius75]

I built and ran this on my 1.13.11 Cluster running in Azure Kubernetes Service. I get an error in the logs that it couldn't query the namespaces API. I installed the serviceaccount in the default namespace. Is there a specific role and rolebinding this code needs to query correctly?

Logs:

@evillgenius75 Yes, you need clusterrole and clusterrolebinding to work with the service account. I will create a helm chart for easy installation soon.

I got clusterRole and clusterRoleBinding working on K8S v1.15.3, no more 403 error but got 404 instead. What should I check for this:

Deployment: web-1, Namespace: default, Replicas: 4, MinReplicas: None, MaxReplicas: None, Schedule: 10 18 * * *
Traceback (most recent call last):
  File "/root/schedule_scaling/schedule_scaling.py", line 274, in <module>

    stacks__to_scale = stacks_to_scale()
  File "/root/schedule_scaling/schedule_scaling.py", line 127, in stacks_to_scale
    for stackset in StackSet.objects(api).filter(namespace=namespace):

    return iter(self.query_cache["objects"])

I am using it for my web-1 deployment as annotation:

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  annotations:
    deployment.kubernetes.io/revision: "3"
    zalando.org/schedule-actions: '[{"schedule": "10 18 * * *", "replicas": "4"}]'

@amelbakry any luck to check on this one, please?

[ezienecker]

Any progress on this?

@ezienecker I found a working fork of this repo: https://github.com/citizensadvice/kube-schedule-scaler

Thanks works like a charm. In this provided repo there is no stackset and a complete example with the correct rbac.
