var TerraformVersionRegex = regexp.MustCompile(`^(\S+)\s(v?\d+\.\d+\.\d+)`)

TerraformVersionRegex verifies that terraform --version output is in one of the following formats: - OpenTofu v1.6.0-dev - Terraform v0.9.5-dev (cad024a5fe131a546936674ef85445215bbc4226+CHANGES) - Terraform v0.13.0-beta2 - Terraform v0.12.27 We only make sure the "v#.#.#" part is present in the output.

Functions

func Action added in v0.66.7 

func Action(opts *options.TerragruntOptions) cli.ActionFunc

func AlreadyHaveLatestCode added in v0.66.7 

func AlreadyHaveLatestCode(terraformSource *terraform.Source, terragruntOptions *options.TerragruntOptions) (bool, error)

AlreadyHaveLatestCode returns true if the specified TerraformSource, of the exact same version, has already been downloaded into the DownloadFolder. This helps avoid downloading the same code multiple times. Note that if the TerraformSource points to a local file path, a hash will be generated from the contents of the source dir. See the ProcessTerraformSource method for more info.

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

CheckTerragruntVersion checks that the currently running Terragrunt version meets the specified version constraint and return an error if it doesn't

func CheckTerragruntVersionMeetsConstraint added in v0.66.7 

func CheckTerragruntVersionMeetsConstraint(currentVersion *version.Version, constraint string) error

func NewCommand 

func NewCommand(opts *options.TerragruntOptions) *cli.Command

func ParseTerraformVersion added in v0.66.7 

func ParseTerraformVersion(versionCommandOutput string) (*version.Version, error)

ParseTerraformVersion parses the output of the terraform --version command

func PopulateTerraformVersion 

func PopulateTerraformVersion(ctx context.Context, terragruntOptions *options.TerragruntOptions) error

PopulateTerraformVersion populates the currently installed version of Terraform into the given terragruntOptions.

func Run 

func Run(ctx context.Context, opts *options.TerragruntOptions) error

Run 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.

func RunTerraformWithRetry added in v0.66.7 

func RunTerraformWithRetry(ctx context.Context, terragruntOptions *options.TerragruntOptions) error

func RunWithTarget 

func RunWithTarget(ctx context.Context, opts *options.TerragruntOptions, target *Target) error

func SetTerragruntInputsAsEnvVars added in v0.66.7 

func SetTerragruntInputsAsEnvVars(terragruntOptions *options.TerragruntOptions, terragruntConfig *config.TerragruntConfig) error

SetTerragruntInputsAsEnvVars sets the inputs from Terragrunt configurations to TF_VAR_* environment variables for OpenTofu/Terraform.

func ShouldCopyLockFile added in v0.67.11 

func ShouldCopyLockFile(args []string, terraformConfig *config.TerraformConfig) bool

ShouldCopyLockFile verifies if the lock file should be copied to the user's working directory Terraform 0.14 now manages a lock file for providers. This can be updated in three ways: * `terraform init` in a module where no `.terraform.lock.hcl` exists * `terraform init -upgrade` * `terraform providers lock`

In any of these cases, terragrunt should attempt to copy the generated `.terraform.lock.hcl`

terraform init is not guaranteed to pull all checksums depending on platforms, if you already have the provider requested in a cache, or if you are using a mirror. There are lots of details at [hashicorp/terraform#27264](https://github.com/hashicorp/terraform/issues/27264#issuecomment-743389837) The `providers lock` sub command enables you to ensure that the lock file is fully populated.

func ToTerraformEnvVars added in v0.66.7 

func ToTerraformEnvVars(opts *options.TerragruntOptions, vars map[string]interface{}) (map[string]string, error)

ToTerraformEnvVars converts the given variables to a map of environment variables that will expose those variables to Terraform. The keys will be of the format TF_VAR_xxx and the values will be converted to JSON, which Terraform knows how to read natively.

func ValidateWorkingDir added in v0.66.7 

func ValidateWorkingDir(terraformSource *terraform.Source) error

ValidateWorkingDir checks if working terraformSource.WorkingDir exists and is directory

func WriteTerragruntDebugFile 

func WriteTerragruntDebugFile(terragruntOptions *options.TerragruntOptions, terragruntConfig *config.TerragruntConfig) error

WriteTerragruntDebugFile will create a tfvars file that can be used to invoke the terraform module in the same way that terragrunt invokes the module, so that you can debug issues with the terragrunt config.

Types

type BackendNotDefined 

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

func (BackendNotDefined) Error 

func (err BackendNotDefined) Error() string

type DownloadingTerraformSourceErr added in v0.54.7 

type DownloadingTerraformSourceErr struct {
	ErrMsg error
	URL    string
}

func (DownloadingTerraformSourceErr) Error added in v0.54.7 

func (err DownloadingTerraformSourceErr) Error() string

type FileCopyGetter 

type FileCopyGetter struct {
	getter.FileGetter

	// List of glob paths that should be included in the copy. This can be used to override the default behavior of
	// Terragrunt, which will skip hidden folders.
	IncludeInCopy []string

	Logger log.Logger
}

FileCopyGetter is 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 

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

Get replaces the original FileGetter 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 

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

GetFile 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
