[Kubernetes] Is there a good way for test auto scaling?

I successfully deployed frappe to my EKS cluster by referring to several docs.

frappe/helm/blob/main/erpnext/README.md

# Frappe / ERPNext

[Frappe](https://frappe.io)/[ERPNext](https://erpnext.com) Free and Open Source Enterprise Resource Planning (ERP).

## TL;DR;

For evaluation setup simple in-cluster NFS server to make the `nfs` storage class with RWX capabilities available for use. Make sure you have default storage class (`kubectl get sc`) already on your cluster before creating `nfs` storage class.

```shell
kubectl create namespace nfs
helm repo add nfs-ganesha-server-and-external-provisioner https://kubernetes-sigs.github.io/nfs-ganesha-server-and-external-provisioner
helm upgrade --install -n nfs in-cluster nfs-ganesha-server-and-external-provisioner/nfs-server-provisioner --set 'storageClass.mountOptions={vers=4.1}' --set persistence.enabled=true --set persistence.size=8Gi
```

Install ERPNext using the `nfs` storage class.

```shell
kubectl create namespace erpnext
helm repo add frappe https://helm.erpnext.com
helm upgrade --install frappe-bench --namespace erpnext frappe/erpnext --set persistence.worker.storageClass=nfs

EKS cluster was successfully created because README had all the information written in detail.
Thank you so much.

This is my values.yaml

Karpenter was also installed successfully.

I want to test if this actually works and if the worker node is actually provisioned.

Is there a good way or tool for load test and check auto scale works?

Thanks!!

Check if https://locust.io works for you. It’s in python.

Other well known tool is https://jmeter.apache.org

Hi. How was your auto scaling test?

MinHyeong-Lee · April 12, 2024, 6:26am

The auto scale worked well, but I wanted to use the load balancer as ALB, but there was a problem with socket io connection when using it as ALB, so I gave up on Kubernetes.

Do not scale socketio deployment or look into enabling sticky session for your LB. Using multiple nodes | Socket.IO

There were no problems when using Nginx Ingress. However, I was trying to use ALB to utilize AWS’s security group, but I thought there was an error in my settings or that Frappe was not suitable for using ALB.

Anyway, it’s a shame, but I’m currently using it well as a single compose.

Thank you
