Use Multiple SSH Keys for Git host websites (Github, Gitlab)

This is guide about how to configure multiple SSH keys for some Git host websites such as Github, Gitlab, among others.

	Maps are a way to create variables that are lookup tables. An example will show this best. Let's extract our AMIs into a map and add support for the us-west-2 region as well:

	variable "amis" {
	type = "map"
	default = {
	"us-east-1" = "ami-b374d5a5"
	"us-west-2" = "ami-4b32be2b"
	}
