Terraform in This Repository

Terraform here is used as a structured inventory + reconciliation layer for existing infrastructure.

It does not replace Docker Compose as runtime deployment authority.

What Terraform is currently used for

• Proxmox VM import/reconciliation for existing VMs.
• Physical host metadata represented in Terraform locals/outputs.
• Select Docker container mirror resources for documentation-oriented tracking.
• Outputs that can support documentation and later downstream tooling.
• Dynu DNS domain/record import and documentation inventory.

What Terraform is not used for (today)

• Replacing services-up.sh / Compose for day-to-day app runtime orchestration.
• Broad, immediate greenfield provisioning of the whole stack.
• Casual apply operations across all infrastructure.
• Replacing Dynu as DNS authority.
• Blindly recreating production DNS records without import/reconciliation.

Directory map

• proxmox/ — imported/reconciled VM resources and host metadata outputs.
• docker/ — selective Docker container import/mirror resources.
• dynu/ — Dynu DNS brownfield import/reconciliation and DNS documentation outputs.
• bootstrap/ — backend/provider bootstrap scaffolding.
• modules/ — placeholder module directories for future stable abstractions.
• scripts/reconcile_from_plan.sh — helper to convert generated plan config into reviewable draft files.

Brownfield workflow standard

1. Import one existing object.
2. Inspect state/plan output.
3. Reconcile hand-maintained Terraform code.
4. Keep ignore_changes narrowly scoped.
5. Iterate to no-op/sane plan for intended scope.
6. Avoid casual apply.

See detailed steps in ../../docs/terraform-workflows.md.

Safe validation commands

From Terraform directories, preferred checks are:

terraform fmt -check -recursive
terraform init -backend=false -input=false
terraform validate

Secrets and state safety

• Do not commit .tfstate*.
• Do not commit real .tfvars values.
• Keep credentials in local, untracked inputs only.
