Error AtlasError Documentation and Resolution

Terraform detected a dependency cycle

Error: Cycle:

Terraform found a circular dependency in the resource graph, so it could not determine a valid order to create or update the resources involved.

Error: Cycle:
  • Two or more resources reference each other in a way that creates a circular dependency.
  • A configuration refactor introduced mutual dependency between resources or modules.
  • Inline rules, outputs, or expressions now require values that are not available until the graph completes.
  1. Identify the resources named in the cycle and remove the mutual dependency.
  2. Split dependent behavior into separate resources or steps so Terraform can order them correctly.
  3. Re-run terraform validate after breaking the cycle to confirm the graph is now acyclic.
