HorizontalPodAutoscaling/hpa chart values

[alextreme]

Feedback from Utrecht, Taiga 329

Bij de helm-chart van Objects wordt geen hpa voor objects-worker ingesteld (terwijl de worker.replicaCount' genegeerd wordt als ‘autoscaling.enabled’=true. Bij laatste zou ‘worker.autoscaling.enabled’ verwacht worden.
Zelfde voor open-zaak-nginx, geen hpa terwijl de ‘nginx.replicaCount’ genegeerd wordt als ‘nginx.autoscaling.enabled’=true

@Tiho0135 of @SilviaAmAm mag dit dubbelchecken en indien nodig corrigeren

I think Sjoerd did not add HPA for all applications in the same way. We can add the HPA for the mentioned above cases.
Whether we need HPA for all application in the same way I cannot say at the moment.

The autoscaler we have is same as in the k8s doc ->
https://raw.githubusercontent.com/kubernetes/website/main/content/en/examples/application/hpa/php-apache.yaml
And only uses cpu and memory. Probably that is enough, just wanted to write my findings.

The helm chart of objecten is indeed missing the hpa for the worker and the one of OZ is missing the one for nginx.

Most applications currently only have HPA for the main app specified.

Todo

• Add worker HPA for objecten and check that the values are correct
• Add nginx HPA for openzaak and check that the values are correct
• Add templates to the maykin-utils-lib, so that they can easily be added to projects
