depends_on

The depends_on meta-argument in Terraform is used to explicitly declare dependencies between resources, ensuring that one or more resources are created or destroyed only after the specified dependent resources have been successfully applied. This is crucial for managing resource dependencies that are not automatically detected by Terraform’s implicit dependency analysis. By using depends_on, you can enforce the correct order of resource creation, modification, or destruction, which is particularly useful in complex infrastructure setups where certain resources must exist or be configured before others can be effectively managed. This meta-argument enhances the reliability and predictability of your Terraform configurations
