Description

Hello guys,

When using google_compute_instance_template, we need to defined the name_prefix who will end up having a name with 63 characters lengh. The thing is for our use cases (and I believe many customer too) need to have more characters.
Here is my error:

Error: "name_prefix" cannot be longer than 37 characters, name is limited to 63

Our current name_prefix 43 characters long so it's exploding the final name who will be suffixed by a date/id 20240418123904392300000001 like xxx-xxxxx-xxxx-xxxx-xxxxx-xxxx-xxxx-xxx-20240418123904392300000001.

According to RFC 1035 the length of a FQDN is limited to 255 characters, and each label (node delimited by a dot in the hostname) is limited to 63 characters.

So our server hostname length will be inferior to 63 characters as it's based on the name_prefix.

Is it something feasible?
Thanks.
