Highly Illogical: Safely Leverage Logic in TF
summary
Claim: OpenTofu/Terraform’s functional-style expressions invite deeply nested, hard-to-debug logic, so put most complexity into locals with atomic values and enforce conventions (either centralized locals or limited inline rules) rather than scattering scripts. Uses: variable validation, outputs, TF_LOG and TF console for inspection, and occasional pre/post Python or Bash for things Terraform cannot do. Practice: emit intermediate outputs for debugging, avoid non‑deterministic interpolation during apply, and prefer clear, testable constructions over one‑line monstrosities.
