• atmos

  8 597 8.6 Go

  👽 Terraform Orchestration Tool for DevOps. Keep environment configuration DRY with hierarchical imports of configurations, inheritance, and WAY more. Native support for Terraform and Helmfile.

  

Check out atmos for a fresh take at managing terraform configurations and terraform workflows. Instead of managing HCL `.tfvar` files manually for configuration, it uses YAML, and supports concepts of imports (via deep merging), remote imports (anything supported by gogetter), mixins, inheritance, multiple-inheritance, vendoring of root modules, workflows, task runners (via custom subcommands), and much more. There's a bit of a learning curve and mind-shift required if coming from a Terragrunt background, but the experience is mindblowing after switching to it. Also, it's not limited to terraform.
