Terraform state — the file that breaks everything

More Terraform projects fail because of state misconfiguration than for any other reason. We cover remote state, locking, workspaces, state surgery, and the recovery patterns we've used to save real client deployments.

What this lesson teaches

· Why local state is a footgun and how to migrate to S3 + DynamoDB locking
· State workspaces vs directory-per-environment — pros and cons
· Importing existing infrastructure: terraform import vs Terraformer
· State surgery: terraform state mv / rm / push — when and how
· Disaster recovery when state is corrupted or out of sync

Modules that don't become unmaintainable

Most Terraform modules start clean and devolve into a nightmare of optional variables. We share our 'good module' template and the rules that keep one usable across 50+ deployments.

What this lesson teaches

· The 'one module per deployable unit' rule
· Versioning modules in a private registry (S3, Terraform Registry, Spacelift)
· Required vs optional variables — the line that prevents bloat
· Outputs as the contract: what's stable, what's allowed to change
· Testing modules with Terratest and OPA conftest
