strict

Documentation

Overview

Package strict provides utilities used by Terragrunt to support a "strict" mode. By default strict mode is disabled, but when enabled, any breaking changes to Terragrunt behavior that is not backwards compatible will result in an error.

Note that any behavior outlined here should be documented in /docs/_docs/04_reference/strict-mode.md

That is how users will know what to expect when they enable strict mode, and how to customize it.

Types

type Control

type Control struct {
	// Error is the error that will be returned when the control is enabled.
	Error error
	// Warning is a warning that will be logged when the control is not enabled.
	Warning string
}

Control represents a control that can be enabled or disabled in strict mode. When the control is enabled, Terragrunt will behave in a way that is not backwards compatible.

func GetStrictControl

func GetStrictControl(name string) (Control, bool)

GetStrictControl returns the strict control with the given name.

func (Control) Evaluate

func (control Control) Evaluate(opts *options.TerragruntOptions) (string, error)

Evaluate returns a warning if the control is not enabled, and an error if the control is enabled.

type Controls

type Controls map[string]Control

func (Controls) Names

func (controls Controls) Names() []string

Names returns the names of all strict controls.

func (Controls) ValidateControlNames

func (controls Controls) ValidateControlNames(strictControlNames []string) error

ValidateControlNames validates that the given control names are valid.
