Install HorizontalPodAutoscaler (HPA) using Helm

Question

I'd like to do all k8s installation, configuration, and maintenance using Helm v3 (v3.7.2).

Thus I have setup yaml templates for:

• deployment
• configmap
• service
• ingress

Yet I can't find any information in the Helm v3 docs on setting up an HPA ( HorizontalPodAutoscaler ). Can this be done using an hpa.yaml that pulls from values.yaml?

Answer 1

Can this be done using an hpa.yaml that pulls from values.yaml?

Yes. HPA is a native Kubernetes resource that you can template out just like you have done for your other resources.

You can see many examples of HPA templates in the Bitnami Helm Charts . For example, apache has an hpa.yaml that is templated-out if .Values.autoscaling.enabled .

Answer 2

Yes. Example, try helm create nginx will create a template project call "nginx", and inside the "nginx" directory you will find a hpa.yaml example.
