Helm3 - validation: chart.metadata is required

Question

I'm in the learning phase of Helm. I'm trying to create helm chart with simple pod definition file. But it's failed with the below error.

Note : If i'm trying to run this command helm install --values=ghost-values.yaml stable/ghost --generate-name. It works fine. Basically this download and install the chart from remote(If i'm not wrong). But I don't know why my local helm chart that I created not working.

➜  Helm $ helm version --short

➜  Helm $

Folder path ->

➜  Helm $ ls guestbook
Chart.yml templates
➜  Helm $

Chart.yml file

➜  guestbook $ cat Chart.yml
apiVersion: v2
name: guestbook
appVersion: "1.0"
description: A Helm chart for Guestbook 1.0

Rename Chart.yml to Chart.yaml, then run again. Here it expects the name should be Chart.yaml

My Chart filename was already called `Chart.yaml` so I created a symlink from `chart.yaml` to `Chart.yaml` and re-ran the `helm install` command and it worked . This (to me) makes no sense based on looking at the link/script which uses `Chart.yaml` – PatS Feb 09 '23 at 23:00
