 # Terraform Atmosphere
-Atmos is a thin wrapper for managing Terraform Workspaces easily. Using the workspace name it will select the correct .tfvar file, defaulting to a qa var file for any other workspace. This is primarily for pipelines but works just as well from the command line. It can process all terraform commands and parameters passing them on directly.

 Note: Atmos will override your default credentials file as this functionality is for use in a docker container or in situations where you would rather use variables.

+Adding `-m` flag will set to manual mode. It will not try to automatically switch workspace per branch. It will adhere to whatever you last set the workspace to.
