Functions

func DefaultConfigPath

func DefaultConfigPath(workingDir string) string

Return the default path to use for the Terragrunt configuration file. The reason this is a method rather than a constant is that older versions of Terragrunt stored configuration in a different file. This method returns the path to the old configuration format if such a file exists and the new format otherwise.

func FindConfigFilesInPath

func FindConfigFilesInPath(rootPath string) ([]string, error)

Returns a list of all Terragrunt config files in the given path or any subfolder of the path. A file is a Terragrunt config file if it has a name as returned by the DefaultConfigPath method and contains Terragrunt config contents as returned by the IsTerragruntConfigFile method.

func IsTerragruntConfigFile

func IsTerragruntConfigFile(path string) (bool, error)

Returns true if the given path corresponds to file that could be a Terragrunt config file. A file could be a Terragrunt config file if:

1. The file exists 2. It is a .terragrunt file, which is the old Terragrunt-specific file format 3. The file contains HCL contents with a terragrunt = { ... } block

func ResolveTerragruntConfigString

func ResolveTerragruntConfigString(terragruntConfigString string, include *IncludeConfig, terragruntOptions *options.TerragruntOptions) (resolved string, finalErr error)

Given a string value from a Terragrunt configuration, parse the string, resolve any calls to helper functions using the syntax ${...}, and return the final value.
