Using Data Sources to improve template

[outscale-hmi]

Data sources allow data to be fetched or computed for use elsewhere in local and configuration.
Use of data sources allows a Builder to make use of information defined outside of Packer.

A data source can output one or more attributes, which can be used by adding their key name to the data source unique identifier, like data....

Example:
"data.amazon-ami.example" {
id = "ami12345"
name = "MyAMI"
creation_date = "01/01/2021"
owner = "123456789"
owner_name = "Some Name"
tags = {"tag1": "value"}
}
