Terraform

Plan and import

• •Don't run terraform plan directly; instead give the command and ask the user to execute it.
• •NEVER run terraform import manually; use import statements instead.

Variables

• •Do not set nullable = true on variables; that is the default and is redundant.
• •Only set nullable = false when the variable must not be null.
• •Avoid default on variables; pass values at the call site if possible.
• •AVOID relying on default values, especially for infra code.

Module structure

• •Single call per concern: one module call per cohesive concern; merge related pieces into one module.

Variables and outputs

• •Remove unused outputs; keep only outputs that are referenced.
• •Minimize environment config; don't parametrize values that never vary across environments.

Descriptions

• •Omit description unless it adds information not visible from the code; remove if unused.
