the panic happens on the access to the non-existant ZoneCacheDuration.
another way to fix this would be to just protect that call when there is no config loaded:

`

         if err == nil {
                    config.ZoneCacheDuration = cfg.OCIZoneCacheDuration
                    p, err = oci.NewOCIProvider(*config, domainFilter, zoneIDFilter, cfg.OCIZoneScope, cfg.DryRun)
            }
    case "rfc2136":

`

Seems a bit more confusing with the break statements.

p, err = oci.NewOCIProvider(*config, domainFilter, zoneIDFilter, cfg.OCIZoneScope, cfg.DryRun)
}
p, err = oci.NewOCIProvider(*config, domainFilter, zoneIDFilter, cfg.OCIZoneScope, cfg.DryRun)
case "rfc2136":
tlsConfig := rfc2136.TLSConfig{
UseTLS: cfg.RFC2136UseTLS,
