Bug 1823667: UPSTREAM: <carry>: Get replicas always from API server #147

enxebre · 2020-05-04T10:17:11Z

When getting Replicas() the local struct in the scalable resource might be stale. To mitigate possible side effects, we want always get a fresh replicas.

This is one in a series of PR to mitigate kubernetes#3104
Once we got all of them merged we'll put a PR upstream.

One nit, otherwise looks good

+	size, err := ng.scalableResource.Replicas()
+	intSize := int(size)
+	if err != nil {
+		return err
 	}


nit: Don't need to declare intSize until the error is checked

Suggested change

size, err := ng.scalableResource.Replicas()

intSize := int(size)

if err != nil {

return err

}

size, err := ng.scalableResource.Replicas()

if err != nil {

return err

}

intSize := int(size)

this looks like a good improvement to me
