what
This conditional check on whether or not to enable reserved instances is too restrictive.
contains(["mysql", "postgresql"], local.reserved_instance_engine)
is saying that only allow it if it is MySQL or PostgreSQL.I think
contains
was originally meant to be like in the literal sense of "contains". Since in my case, I'm usingaurora-postgresql
, and it fails this check, yet it is one of the options for reserved instances.why
endswith
might be better, but it is TOO restrictive, seeing that there's so many options.Additionally, Terraform will fail if user specifies the wrong engine type. There's no need for this check.
