Minimum number of auto-scaled instances. Defaults to 0, thus, the container will stop
if it doesn't receive requests for a period of time and the following request will make
the container start from cold.
This should be carefully considered for containers that take a significant amount of
time starting from cold.

If non-empty, a domain mapping will be created for the webapp from this domain
to point to the webapp. The domain must first have been verified by Google and
the account being used by the google provider must have been added as an owner.

If and only if a domain mapping has been created, the
