Constants

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

const TerragruntCacheDir = ".terragrunt-cache"

TerragruntOptions represents options that configure the behavior of the Terragrunt program

func NewTerragruntOptions

func NewTerragruntOptions(terragruntConfigPath string) (*TerragruntOptions, error)

Create a new TerragruntOptions object with reasonable defaults for real usage

func NewTerragruntOptionsForTest

func NewTerragruntOptionsForTest(terragruntConfigPath string) (*TerragruntOptions, error)

Create a new TerragruntOptions object with reasonable defaults for test usage

func (*TerragruntOptions) AppendTerraformCliArgs

func (terragruntOptions *TerragruntOptions) AppendTerraformCliArgs(argsToAppend ...string)

Appends the given argsToAppend after the current TerraformCliArgs

func (*TerragruntOptions) Clone

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

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

func (terragruntOptions *TerragruntOptions) InsertTerraformCliArgs(argsToInsert ...string)

Inserts the given argsToInsert after the terraform command argument, but before the remaining args

func (*TerragruntOptions) TerraformDataDir

func (terragruntOptions *TerragruntOptions) TerraformDataDir() string

TerraformDataDir returns Terraform data directory (.terraform by default, overridden by $TF_DATA_DIR envvar)
