const DEFAULT_MAX_FOLDERS_TO_CHECK = 100
const DEFAULT_MAX_RETRY_ATTEMPTS = 3
const DEFAULT_PARALLELISM = math.MaxInt32
no limits on parallelism by default (limited by GOPROCS)
const DEFAULT_SLEEP = 5 * time.Second
const DefaultTFDataDir = ".terraform"
const TERRAFORM_DEFAULT_PATH = "terraform"
TERRAFORM_DEFAULT_PATH just takes terraform from the path

TerragruntOptions represents options that configure the behavior of the Terragrunt program
func NewTerragruntOptions ¶ added in v0.6.0
func NewTerragruntOptions(terragruntConfigPath string) (*TerragruntOptions, error)
Create a new TerragruntOptions object with reasonable defaults for real usage
func NewTerragruntOptionsForTest ¶ added in v0.6.0
func NewTerragruntOptionsForTest(terragruntConfigPath string) (*TerragruntOptions, error)
Create a new TerragruntOptions object with reasonable defaults for test usage
func (*TerragruntOptions) AppendTerraformCliArgs ¶ added in v0.13.0
func (terragruntOptions *TerragruntOptions) AppendTerraformCliArgs(argsToAppend ...string)
Appends the given argsToAppend after the current TerraformCliArgs
func (*TerragruntOptions) Clone ¶ added in v0.6.0
func (terragruntOptions *TerragruntOptions) Clone(terragruntConfigPath string) *TerragruntOptions
Create a copy of this TerragruntOptions, but with different values for the given variables. This is useful for creating a TerragruntOptions that behaves the same way, but is used for a Terraform module in a different folder.
func (*TerragruntOptions) DataDir ¶ added in v0.20.1
func (terragruntOptions *TerragruntOptions) DataDir() string
DataDir returns the Terraform data directory prepended with the working directory path, or just the Terraform data directory if it is an absolute path.
func (*TerragruntOptions) InsertTerraformCliArgs ¶ added in v0.13.0
func (terragruntOptions *TerragruntOptions) InsertTerraformCliArgs(argsToInsert ...string)
Inserts the given argsToInsert after the terraform command argument, but before the remaining args
func (*TerragruntOptions) TerraformDataDir ¶ added in v0.23.24
func (terragruntOptions *TerragruntOptions) TerraformDataDir() string
TerraformDataDir returns Terraform data directory (.terraform by default, overridden by $TF_DATA_DIR envvar)
