| # This workflow checks the status of infrastructure deployments to see whether | |
| # infrastructure code configuration matches the actual state of the infrastructure. | |
| # It does this by checking that Terraform plans show an empty diff (no changes) | |
| # across all root modules and backend configurations. | |
