Pulling backend image from private OCI registry with LocalAI Helm chart

[astkwcz]

Hi,

I'm trying to use custom backends from private registry. I'm following this structure: https://github.com/mudler/LocalAI/blob/master/backend/index.yaml for the backend gallery file, I'm unsure how to provide credentials for logging in to that registry.
I can see that the oci download has some struct and method for auth (https://github.com/mudler/LocalAI/blob/master/pkg/oci/image.go#L34) but didn't find how to configure it.

I'm deploying LocalAI via Helm Chart (official go-skynet one) - are there env vars that LocalAI expects or sth like that? I can see in the helm chart that imagePullSecrets are not mouted to the pod automatically, I can handle that in values yml but need guidance on where those should be mounted or if secrets shall be placed in some env var?

Thanks in advance :)
