Functions

func DefaultWorkingAndDownloadDirs

func DefaultWorkingAndDownloadDirs(terragruntConfigPath string) (string, string, error)

Get the default working and download directories for the given Terragrunt config path

Types

type TerragruntOptions

type TerragruntOptions struct {
	// Location of the Terragrunt config file
	TerragruntConfigPath string

	// Location of the terraform binary
	TerraformPath string

	// Current Terraform command being executed by Terragrunt
	TerraformCommand string

	// Version of terraform (obtained by running 'terraform version')
	TerraformVersion *version.Version

	// Whether we should prompt the user for confirmation or always assume "yes"
	NonInteractive bool

	// Whether we should automatically run terraform init if necessary when executing other commands
	AutoInit bool

	// CLI args that are intended for Terraform (i.e. all the CLI args except the --terragrunt ones)
	TerraformCliArgs []string

	// The working directory in which to run Terraform
	WorkingDir string

	// The logger to use for all logging
	Logger *log.Logger

	// Environment variables at runtime
	Env map[string]string

	// Download Terraform configurations from the specified source location into a temporary folder and run
	// Terraform in that temporary folder
	Source string

	// If set to true, delete the contents of the temporary folder before downloading Terraform source code into it
	SourceUpdate bool

	// Download Terraform configurations specified in the Source parameter into this folder
	DownloadDir string

	// The ARN of an IAM Role to assume before running Terraform
	IamRole string

	// If set to true, continue running *-all commands even if a dependency has errors. This is mostly useful for 'output-all <some_variable>'. See https://github.com/gruntwork-io/terragrunt/issues/193
	IgnoreDependencyErrors bool

	// If you want stdout to go somewhere other than os.stdout
	Writer io.Writer

	// If you want stderr to go somewhere other than os.stderr
	ErrWriter io.Writer

	// When searching the directory tree, this is the max folders to check before exiting with an error. This is
	// exposed here primarily so we can set it to a low value at test time.
	MaxFoldersToCheck int

	// Unix-style glob of directories to exclude when running *-all commands
	ExcludeDirs []string

	// A command that can be used to run Terragrunt with the given options. This is useful for running Terragrunt
	// multiple times (e.g. when spinning up a stack of Terraform modules). The actual command is normally defined
	// in the cli package, which depends on almost all other packages, so we declare it here so that other
	// packages can use the command without a direct reference back to the cli package (which would create a
	// circular dependency).

}

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) InsertTerraformCliArgs

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

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