Docs: What is the type in naming variables?

[mikalai-hryb]

When I was reading about the naming convention I faced this line

Good structure for the name of output looks like {name}_{type}_{attribute} , where:

1. {name} is a resource or data source name without a provider prefix. {name} for aws_subnet is subnet, foraws_vpc it is vpc.
2. {type} is a type of a resource sources
3. {attribute} is an attribute returned by the output
4. See examples.

It's not clear what type is and how it can look. I was not able to understand it from the examples https://www.terraform-best-practices.com/naming#code-examples-of-output

It seems the examples use {name}_{attribute} pattern

Can someone please explain to me what type is?

[antonbabenko]

name of the resource is this, so it should be omitted:

3. If the output is returning a value with interpolation functions and multiple resources, {name} and {type} there should be as generic as possible (this as prefix should be omitted).

Not good: this_security_group_id Good: security_group_id
