#security_groups(type) ⇒ Object

type: elb or ecs NOTE: Application ELBs always seem to need a security group even though the docs say its not required However, there’s a case where no ELB is created for a worker tier and if the settings are all blank CloudFormation fails to resolve and splits out this error:

Template error: every Fn::Split object requires two parameters

So we will not assign security groups at all for case of workers with no security groups at all.
