Add extra datasources when installing through kustomize

[Ulrar]

Hi,

I'm using ArgoCD to install this through kustomize, and while adding dashboards is fairly straightforward by mounting them under /grafana-dashboard-definitions, adding datasources isn't clear to me.

What's the way to add extra datasources ? I tried mounting them under /etc/grafana/provisioning/datasources/ but that of course does not work, presumably because that's already mounted from a secret so it's read only.

Thanks
