Install ArgoCD lovely plugin via helm values.yaml file configuration

values-lovely-plugin.yaml

# Ah yes, the lovely, undocumented, and not-at-all-irrationally-difficult-to-understand ArgoCD method of chart customisation - plugins...

# If you are struggling to install the "lovely" plugin (or any plugin for that matter) with the ArgoCD Helm chart, this Gist could help you.
# Include this values config file as part of a Helm/Helmfile values argument to include the "lovely" plugin in your ArgoCD deployment.
# "Lovely" includes several popular tools for helm chart management, including the brilliant Helmfile, which itself includes
# "Vals" for secrets management.
