My favorite terraform coding Rule

The naming convention for our Terraform environment was one of our favorites because it clearly indicated the declaration location.
So, I built my favorite terraform coding rule via tflint.

here

The rule is very simple.
Every resource must defined in the its resource-name file.

• variable,locals,output,provider,module are all defined in variable.tf,locals.tf,output.tf,provider.tf,module.tf
• data are all defined in data_<data_type>.tf
• resource are all defined in <resource_type>.tf

Installation

.tflint.hcl

plugin "file-name-is-resource-name" {
enabled = true
source = "github.com/shoppingjaws/tflint-ruleset-file-name-is-resource-name"
version = "1.0.0"
}

Settings

File name rules that should be defined can be overwritten

rule "file_name_is_resource_name" {
enabled = true
module_file_name_pattern = "^main.tf$"
variable_file_name_pattern= "^variable.tf$"
locals_file_name_pattern= "^locals.tf$"
provider_file_name_pattern= "^provider.tf$"
output_file_name_pattern= "^output.tf$"
module_file_name_pattern= "^module.tf$"
data_file_name_pattern= "^data_.*.tf$"
}

Pros and cons of this rule

Pros

• Easy to search Using the function to search by file name in vscode, etc., makes it easy to narrow down by resource name
• Easy to review The creator's intentions and habits are not included, and the declaration is uniquely determined, reducing fluctuations

Cons

• If tfstate is not divided, a large number of resources will be declared in one file

I'd be happy to receive feedback
