Functions

func CheckForCycles

func CheckForCycles(modules []*TerraformModule) error

Check for dependency cycles in the given list of modules and return an error if one is found

func RunModules

func RunModules(modules []*TerraformModule) error

Run the given map of module path to runningModule. To "run" a module, execute the RunTerragrunt command in its TerragruntOptions object. The modules will be executed in an order determined by their inter-dependencies, using as much concurrency as possible.

func RunModulesReverseOrder

func RunModulesReverseOrder(modules []*TerraformModule) error

Run the given map of module path to runningModule. To "run" a module, execute the RunTerragrunt command in its TerragruntOptions object. The modules will be executed in the reverse order of their inter-dependencies, using as much concurrency as possible.
