Helm must be installed to use the charts. Please refer to Helm's documentation to get started.

Once Helm has been set up correctly, add the repo as follows:

helm repo add argocd-extension-pod-files https://wei840222.github.io/argocd-extension-pod-files
helm repo update

If you had already added this repo earlier, run helm repo update to retrieve the latest versions of the packages. You can then run helm search repo <alias> to see the charts.

To install the chart:

helm install -n <argocd namespace> argocd-extension-pod-files argocd-extension-pod-files/argocd-extension-pod-files

To uninstall the chart:

helm delete -n <argocd namespace> argocd-extension-pod-files
