Test Environment

[Grifs]

.organization is removed from the component config. (Can still be undone easily)

So far no additional fallback was added in case the .organization in package config is empty.

Would you like to add the changes suggested by comment #2 ?

You mean this part?

    val targetRegistryWithFallback = target_registry.orElse(config.links.docker_registry).filter(_.nonEmpty)

If so, this is already present. If something else, could you please elaborate?
