Root Cause

Terraform dependency graph has a circular reference between resources.

generic

Workarounds

  1. 92% success Identify the cycle with terraform graph | dot -Tsvg > graph.svg and break it 
    Visualize dependencies and remove the circular reference

    Sources: https://developer.hashicorp.com/terraform/cli/commands/graph

  2. 88% success Use data sources or outputs instead of direct references to break the cycle 
    Replace direct resource references with data source lookups where possible

Dead Ends

Common approaches that don't work:

  1. Adding depends_on to both resources 90% fail

    Explicitly creates the cycle that Terraform detected

  2. Using terraform taint on one of the resources 80% fail

    Does not break the cycle; just marks for recreation
