Constructor Details

#initialize(opts = {}, prnt = Ec2.new) ⇒ Ec2RemoteInstance

A new instance will be created from the passed in hash.

This hash of passed in values will be converted to methods on this instance. The parent clouds describe_instances list will be searched for the first one matching any of this instance’s provided unique identifiers. If an instance is found, this instance’s properties will be set to the properties provided If the found instance has properties of the same key as the provided options, the found instance’s values will override the passed in options
