var CUSTOM_USAGE_TEXT = `` /* 3189-byte string literal not displayed */

Since Terragrunt is just a thin wrapper for Terraform, and we don't want to repeat every single Terraform command in its definition, we don't quite fit into the model of any Go CLI library. Fortunately, urfave/cli allows us to override the whole template used for the Usage Text.

TODO: this description text has copy/pasted versions of many Terragrunt constants, such as command names and file names. It would be easy to make this code DRY using fmt.Sprintf(), but then it's hard to make the text align nicely. Write some code to take generate this help text automatically, possibly leveraging code that's part of urfave/cli.

var TERRAFORM_VERSION_REGEX = regexp.MustCompile("Terraform (v?[\\d\\.]+)(?:-dev)?(?: .+)?")

The terraform --version output is of the format: Terraform v0.9.5-dev (cad024a5fe131a546936674ef85445215bbc4226+CHANGES) where -dev and (commitid+CHANGES) is for custom builds or if TF_LOG is set for debug purposes

Functions

func CheckTerraformVersion added in v0.12.5 

func CheckTerraformVersion(constraint string, terragruntOptions *options.TerragruntOptions) error

Check that the currently installed Terraform version works meets the specified version constraint and return an error if it doesn't

func CreateTerragruntCli 

func CreateTerragruntCli(version string, writer io.Writer, errwriter io.Writer) *cli.App

Create the Terragrunt CLI App

func ParseTerragruntOptions added in v0.6.0 

func ParseTerragruntOptions(cliContext *cli.Context) (*options.TerragruntOptions, error)

Parse command line options that are passed in for Terragrunt

func PopulateTerraformVersion added in v0.13.0 

func PopulateTerraformVersion(terragruntOptions *options.TerragruntOptions) error

Populate the currently installed version of Terraform into the given terragruntOptions

func RunTerragrunt added in v0.21.7 

func RunTerragrunt(terragruntOptions *options.TerragruntOptions) error

Downloads terraform source if necessary, then runs terraform with the given options and CLI args. This will forward all the args and extra_arguments directly to Terraform.

Types

type ArgMissingValue added in v0.6.0 

type ArgMissingValue string

func (ArgMissingValue) Error added in v0.6.0 

func (err ArgMissingValue) Error() string

type ArgumentNotAllowed added in v0.13.0 

type ArgumentNotAllowed struct {
	Argument string
	Message  string
}

func (ArgumentNotAllowed) Error added in v0.13.0 

func (err ArgumentNotAllowed) Error() string

type BackendNotDefined added in v0.13.5 

type BackendNotDefined struct {
	Opts        *options.TerragruntOptions
	BackendType string
}

func (BackendNotDefined) Error added in v0.13.5 

func (err BackendNotDefined) Error() string

type FileCopyGetter added in v0.19.1 

type FileCopyGetter struct {
	getter.FileGetter
}

A custom getter.Getter implementation that uses file copying instead of symlinks. Symlinks are faster and use less disk space, but they cause issues in Windows and with infinite loops, so we copy files/folders instead.

func (*FileCopyGetter) Get added in v0.19.1 

func (g *FileCopyGetter) Get(dst string, u *url.URL) error

The original FileGetter does NOT know how to do folder copying (it only does symlinks), so we provide a copy implementation here

func (*FileCopyGetter) GetFile added in v0.19.1 

func (g *FileCopyGetter) GetFile(dst string, u *url.URL) error

The original FileGetter already knows how to do file copying so long as we set the Copy flag to true, so just delegate to it

type InitNeededButDisabled added in v0.13.0 

type InitNeededButDisabled string

func (InitNeededButDisabled) Error added in v0.13.0 

func (err InitNeededButDisabled) Error() string

type InvalidTerraformVersion added in v0.12.5 

type InvalidTerraformVersion struct {
	CurrentVersion     *version.Version
	VersionConstraints version.Constraints
}

func (InvalidTerraformVersion) Error added in v0.12.5 

func (err InvalidTerraformVersion) Error() string

type InvalidTerraformVersionSyntax added in v0.12.5 

type InvalidTerraformVersionSyntax string

func (InvalidTerraformVersionSyntax) Error added in v0.12.5 

func (err InvalidTerraformVersionSyntax) Error() string

type MaxRetriesExceeded added in v0.17.0 

type MaxRetriesExceeded struct {
	Opts *options.TerragruntOptions
}

type TerraformSource struct {
	// A canonical version of RawSource, in URL format
	CanonicalSourceURL *url.URL

	// The folder where we should download the source to
	DownloadDir string

	// The folder in DownloadDir that should be used as the working directory for Terraform
	WorkingDir string

	// The path to a file in DownloadDir that stores the version number of the code
	VersionFile string
}

This struct represents information about Terraform source code that needs to be downloaded

func (*TerraformSource) String added in v0.9.7 

func (src *TerraformSource) String() string

type TerragruntInfoGroup added in v0.18.5 

type TerragruntInfoGroup struct {
