Chart: Deploy `PodDisruptionBudget` with KEDA. #11032

StuxxNet · 2024-02-27T18:20:01Z

What this PR does / why we need it:

Currently we deploy the PDB only if Keda is enabled. This PR tries to address this adding a new entry to the "if" statement to make it consider Keda also.

Types of changes

New feature (non-breaking change which adds functionality)

Which issue/s this PR fixes

fixes #10083

How Has This Been Tested?

The testing was done by creating a fresh deployment of the Ingress Nginx in a brand new Kind cluster running Kubernetes 1.29. Below you can see that the corresponding PDB object was created when the values for Keda were passed to the chart:

Welcome @StuxxNet!

It looks like this is your first PR to kubernetes/ingress-nginx 🎉. Please refer to our pull request process documentation to help your PR have a smooth ride to approval.

You will be prompted by a bot to use commands during the review process. Do not be afraid to follow the prompts! It is okay to experiment. Here is the bot commands documentation.

You can also check if kubernetes/ingress-nginx has its own contribution guidelines.

You may want to refer to our testing guide if you run into trouble with your tests not passing.

If you are having difficulty getting your pull request seen, please follow the recommended escalation practices. Also, for tips and tricks in the contribution process you may want to read the Kubernetes contributor cheat sheet. We want to make sure your contribution gets all the attention it needs!

Thank you, and welcome to Kubernetes. 😃

k8s-ci-robot · 2024-02-27T18:20:11Z

Hi @StuxxNet. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

+{{- if .Values.controller.autoscaling.enabled }}
+{{- $replicas = .Values.controller.autoscaling.minReplicas }}
+{{- else if .Values.controller.keda.enabled }}
+{{- $replicas = .Values.controller.keda.minReplicas }}


Don't we need to add some docs for this?

What if the user enable both by mistake?
Can we try to use the OR instead or that does not work?

/hold for clarification

Hm, yeah, I get your point. HPA and KEDA being mutually exclusive always was a problem and looking at the particular resource templates, we are not even preventing that in there.

So right now what you see above is pretty close the best we can get without making the conditions too complex and unreadable.

I created an issue for improving and aligning that everywhere. But for now, I'd just go on and merge this PR. Aligning all these conditions is out of scope here.

That's the issue I created: #10814
