dependency chart requires adding repo definition first

[fty4]

Hello everyone,

I just tested this action and find it very useful.

When using the ct install inside a workflow I have a problem with the dependencies.
The chart that will be installed depends on another chart and Helm expects the repository already be present.

Here is the message from the run:

Error message

Installing charts...
Version increment checking disabled.

------------------------------------------------------------------------------------------------------------------------
 Charts to be processed:
------------------------------------------------------------------------------------------------------------------------
 mychart => (version: "0.2.3", path: "./")
------------------------------------------------------------------------------------------------------------------------

Error: no repository definition for [https://chart.url/.](https://chart.url/) Please add the missing repos via 'helm repo add'
Error: Error installing charts: Error building dependencies for chart 'mychart  => (version: "0.2.3", path: "./")': Error waiting for process: exit status 1

Error installing charts: Error building dependencies for chart 'mychart  => (version: "0.2.3", path: "./")': Error waiting for process: exit status 1
Error: Process completed with exit code 1.

In my local dev environment this repo to the chart is already added - but inside the runner not.
Is there any best practice how the charts can be added automatically (by ct?)?

Currently my approach would be to read out all dependencies.*.repository values from the Chart.yaml and add them in an extra step via bash.

if the dependent chart is public and has a release for that you can just add it in the config.

like

chart-repos:
  - ingress-nginx=https://kubernetes.github.io/ingress-nginx
  - sigstore=https://sigstore.github.io/helm-charts
