Unable to deploy erpnext kubernetes cluster locally

Install / Update Deployment

I have successfully deploy erpnext using the official helm chart to aws eks

But I am having troubled doing the same thing on local using k3d.

I created a new site erp.cluster.local
I have the ingress

apiVersion: networking.k8s.io/v1

the ingress controller synced the ingress successfully.

I added the domain in /etc/hosts/

172.22.0.2 		erp.cluster.local

However when I am trying to access the site via ‘erp.cluster.local’ the ingress controller does not direct me to the correct service. (it keeps directing me to upstream-default-backend) (nginx-404)

Can someone help me on this ?

If you created the cluster with -p 80:80@loadbalancer -p 443:443@loadbalancer

e.g.

k3d cluster create devcluster --api-port 127.0.0.1:6443 -p 80:80@loadbalancer -p 443:443@loadbalancer --k3s-arg "--disable=traefik@server:0"

then add 127.0.0.1 erp.cluster.local in /etc/hosts. That seems to work for me.

I create a sites ending with .localhost instead of .cluster.local. By doing that I don’t need to edit /etc/hosts and I can access the sites from host machine.

I use linux. I’ve not used it on any other OS.

Why are you trying it locally? Are you trying to develop any operator?

Hi @revant_one
I tried to do a clean install following your instruction but the same problem happens. Must be some problem with my machine :frowning:
I am just trying to migrate from AWS to onprem server.
