Bug when using gcr on the examples values.yaml

[gabo1208]

Bug description:

When I use gcr.io as the registry on any example configuration, the builder registry is set to index.docker. But when I use us.gcr.io for example it works correctly, don't know if this is intended but I'll report it and see if it can help =)

Steps to reproduce:

Please provide a set of steps to reproduce the behavior (example):

1. Run any sample
2. Use gcr.io as a registry
3. Then use something like us.gcr.io

Expected behavior:

It should detect that gcr.io is a valid registry since I have the credentials configured for it without any prefix.

Actual behavior:

Builder try to use index.docker as the image registry
