Functions ¶
func ClearOutputCache ¶ added in v0.21.2
func ClearOutputCache()
ClearOutputCache clears the output cache. Useful during testing.
func FindConfigFilesInPath ¶ added in v0.10.0
func FindConfigFilesInPath(rootPath string, terragruntOptions *options.TerragruntOptions) ([]string, error)
Returns a list of all Terragrunt config files in the given path or any subfolder of the path. A file is a Terragrunt config file if it has a name as returned by the DefaultConfigPath method
func GetDefaultConfigPath ¶ added in v0.21.6
Return the default path to use for the Terragrunt configuration that exists within the path giving preference to `terragrunt.hcl`
func GetTerraformSourceUrl ¶ added in v0.28.3
func GetTerraformSourceUrl(terragruntOptions *options.TerragruntOptions, terragruntConfig *TerragruntConfig) (string, error)
There are two ways a user can tell Terragrunt that it needs to download Terraform configurations from a specific URL: via a command-line option or via an entry in the Terragrunt configuration. If the user used one of these, this method returns the source URL or an empty string if there is no source url
func GetTerragruntSourceForModule ¶ added in v0.23.9
func GetTerragruntSourceForModule(sourcePath string, modulePath string, moduleTerragruntConfig *TerragruntConfig) (string, error)
If one of the xxx-all commands is called with the --terragrunt-source parameter, then for each module, we need to build its own --terragrunt-source parameter by doing the following:
1. Read the source URL from the Terragrunt configuration of each module 2. Extract the path from that URL (the part after a double-slash) 3. Append the path to the --terragrunt-source parameter
Example:
--terragrunt-source: /source/infrastructure-modules source param in module's terragrunt.hcl: git::git@github.com:acme/infrastructure-modules.git//networking/vpc?ref=v0.0.1
This method will return: /source/infrastructure-modules//networking/vpc
func ParseAndDecodeVarFile ¶ added in v0.28.11
ParseAndDecodeVarFile uses the HCL2 file to parse the given varfile string into an HCL file body, and then decode it into the provided output.
func TerragruntConfigAsCty ¶ added in v0.33.2
func TerragruntConfigAsCty(config *TerragruntConfig) (cty.Value, error)
Serialize TerragruntConfig struct to a cty Value that can be used to reference the attributes in other config. Note that we can't straight up convert the struct using cty tags due to differences in the desired representation. Specifically, we want to reference blocks by named attributes, but blocks are rendered to lists in the TerragruntConfig struct, so we need to do some massaging of the data to convert the list of blocks in to a map going from the block name label to the block value.
func TerragruntConfigAsCtyWithMetadata ¶ added in v0.38.6
func TerragruntConfigAsCtyWithMetadata(config *TerragruntConfig) (cty.Value, error)
Types ¶
type CatalogConfig ¶ added in v0.54.5
type CatalogConfig struct {
URLs []string `hcl:"urls,attr" cty:"urls"`
}
func ReadCatalogConfig ¶ added in v0.54.9
func ReadCatalogConfig(parentCtx context.Context, opts *options.TerragruntOptions) (*CatalogConfig, error)
We want users to be able to browse to any folder in an `infra-live` repo, run `terragrunt catalog` (with no URL) arg. ReadCatalogConfig looks for the "nearest" `terragrunt.hcl` in the parent directories if the given `opts.TerragruntConfigPath` does not exist. Since our normal parsing `ParseConfig` does not always work, as some `terragrunt.hcl` files are meant to be used from an `include` and/or they might use `find_in_parent_folders` and they only work from certain child folders, it parses this file to see if the config contains `include{...find_in_parent_folders()...}` block to determine if it is the root configuration. If it finds `terragrunt.hcl` that already has `include`, then read that configuration as is, oterwise generate a stub child `terragrunt.hcl` in memory with an `include` to pull in the one we found. Unlike "RoadTerragruntConfig" func, it ignores any configuration errors not related to the "catalog" block.
func (*CatalogConfig) String ¶ added in v0.54.5
func (conf *CatalogConfig) String() string
type CouldNotEvaluateAllLocalsError ¶ added in v0.19.14

func (err CouldNotResolveTerragruntConfigInFileError) Error() string
type CtyJsonOutput ¶ added in v0.19.0
type CtyJsonOutput struct { Value map[string]interface{} Type interface{} }
When you convert a cty value to JSON, if any of that types are not yet known (i.e., are labeled as DynamicPseudoType), cty's Marshall method will write the type information to a type field and the actual value to a value field. This struct is used to capture that information so when we parse the JSON back into a Go struct, we can pull out just the Value field we need.
type Dependency ¶ added in v0.19.20

Use MockOutputsMergeStrategyWithState MockOutputsMergeWithState *bool `hcl:"mock_outputs_merge_with_state,attr" cty:"mock_outputs_merge_with_state"` MockOutputsMergeStrategyWithState *MergeStrategyType `hcl:"mock_outputs_merge_strategy_with_state" cty:"mock_outputs_merge_strategy_with_state"` // Used to store the rendered outputs for use when the config is imported or read with `read_terragrunt_config` RenderedOutputs *cty.Value `cty:"outputs"` Inputs *cty.Value `cty:"inputs"` }
func (*Dependency) DeepMerge ¶ added in v0.31.4
func (targetDepConfig *Dependency) DeepMerge(sourceDepConfig Dependency) error
DeepMerge will deep merge two Dependency configs, updating the target. Deep merge for Dependency configs is defined as follows:
- For simple attributes (bools and strings), the source will override the target.
- For MockOutputs, the two maps will be deeply merged together. This means that maps are recursively merged, while lists are concatenated together.
- For MockOutputsAllowedTerraformCommands, the source will be concatenated to the target.
Note that RenderedOutputs is ignored in the deep merge operation.

TerragruntConfig represents a parsed and expanded configuration NOTE: if any attributes are added, make sure to update terragruntConfigAsCty in config_as_cty.go
func ParseConfig ¶ added in v0.54.16
func ParseConfig(ctx *ParsingContext, file *hclparse.File, includeFromChild *IncludeConfig) (*TerragruntConfig, error)
Parse the Terragrunt config contained in the given hcl file and merge it with the given include config (if any). Note that the config parsing consists of multiple stages so as to allow referencing of data resulting from parsing previous config. The parsing order is:
- Parse include. Include is parsed first and is used to import another config. All the config in the include block is then merged into the current TerragruntConfig, except for locals (by design). Note that since the include block is parsed first, you cannot reference locals in the include block config.
- Parse locals. Since locals are parsed next, you can only reference other locals in the locals block. Although it is possible to merge locals from a config imported with an include block, we do not do that here to avoid complicated referencing issues. Please refer to the globals proposal for an alternative that allows merging from included config: https://github.com/gruntwork-io/terragrunt/issues/814 Allowed References: - locals
- Parse dependency blocks. This includes running `terragrunt output` to fetch the output data from another terragrunt config, so that it is accessible within the config. See PartialParseConfigString for a way to parse the blocks but avoid decoding. Note that this step is skipped if we already retrieved all the dependencies (which is the case when parsing included config files). This is determined by the dependencyOutputs input parameter. Allowed References: - locals
- Parse everything else. At this point, all the necessary building blocks for parsing the rest of the config are available, so parse the rest of the config. Allowed References: - locals - dependency
- Merge the included config with the parsed config. Note that all the config data is mergable except for `locals` blocks, which are only scoped to be available within the defining config.
func ParseConfigFile ¶ added in v0.6.0
func ParseConfigFile(opts *options.TerragruntOptions, ctx *ParsingContext, configPath string, includeFromChild *IncludeConfig) (*TerragruntConfig, error)
Parse the Terragrunt config file at the given path. If the include parameter is not nil, then treat this as a config included in some other config file when resolving relative paths.

func PartialParseConfigString ¶ added in v0.19.20
func PartialParseConfigString(ctx *ParsingContext, configPath, configString string, include *IncludeConfig) (*TerragruntConfig, error)
PartialParseConfigString partially parses and decodes the provided string. Which blocks/attributes to decode is controlled by the function parameter decodeList. These blocks/attributes are parsed and set on the output TerragruntConfig. Valid values are:
- DependenciesBlock: Parses the `dependencies` block in the config
- DependencyBlock: Parses the `dependency` block in the config
- TerraformBlock: Parses the `terraform` block in the config
- TerragruntFlags: Parses the boolean flags `prevent_destroy` and `skip` in the config
- TerragruntVersionConstraints: Parses the attributes related to constraining terragrunt and terraform versions in the config.
- RemoteStateBlock: Parses the `remote_state` block in the config
Note that the following blocks are always decoded: - locals - include Note also that the following blocks are never decoded in a partial parse: - inputs
func ReadTerragruntConfig ¶
func ReadTerragruntConfig(terragruntOptions *options.TerragruntOptions) (*TerragruntConfig, error)
Read the Terragrunt config file from its default location

func TerragruntConfigFromPartialConfig(ctx *ParsingContext, file *hclparse.File, includeFromChild *IncludeConfig) (*TerragruntConfig, error)
Wrapper of PartialParseConfigString which checks for cached configs. filename, configString, includeFromChild and decodeList are used for the cache key, by getting the default value (%#v) through fmt.
func (*TerragruntConfig) DeepMerge ¶ added in v0.31.4
func (targetConfig *TerragruntConfig) DeepMerge(sourceConfig *TerragruntConfig, terragruntOptions *options.TerragruntOptions) error
DeepMerge performs a deep merge of the given sourceConfig into the targetConfig. Deep merge is defined as follows:
- For simple types, the source overrides the target.
- For lists, the two attribute lists are combined together in concatenation.
- For maps, the two maps are combined together recursively. That is, if the map keys overlap, then a deep merge is performed on the map value.
- Note that some structs are not deep mergeable due to an implementation detail. This will change in the future. The following structs have this limitation:
- remote_state
- generate
- Note that the following attributes are deliberately omitted from the merge operation, as they are handled differently in the parser:
- dependency blocks (TerragruntDependencies) [These blocks need to retrieve outputs, so we need to merge during the parsing step, not after the full config is decoded]
- locals [These blocks are not merged by design]
func (*TerragruntConfig) GetFieldMetadata ¶ added in v0.38.6
func (conf *TerragruntConfig) GetFieldMetadata(fieldName string) (map[string]string, bool)
GetFieldMetadata return field metadata by field name.
func (*TerragruntConfig) GetIAMRoleOptions ¶ added in v0.35.1
func (conf *TerragruntConfig) GetIAMRoleOptions() options.IAMRoleOptions
GetIAMRoleOptions is a helper function that converts the Terragrunt config IAM role attributes to options.IAMRoleOptions struct.
func (*TerragruntConfig) GetMapFieldMetadata ¶ added in v0.38.6
func (conf *TerragruntConfig) GetMapFieldMetadata(fieldType, fieldName string) (map[string]string, bool)
GetMapFieldMetadata return field metadata by field type and name.
func (*TerragruntConfig) Merge ¶ added in v0.31.2
func (targetConfig *TerragruntConfig) Merge(sourceConfig *TerragruntConfig, terragruntOptions *options.TerragruntOptions) error
Merge performs a shallow merge of the given sourceConfig into the targetConfig. sourceConfig will override common attributes defined in the targetConfig. Note that this will modify the targetConfig. NOTE: the following attributes are deliberately omitted from the merge operation, as they are handled differently in the parser:
- locals [These blocks are not merged by design]
NOTE: dependencies block is a special case and is merged deeply. This is necessary to ensure the configstack system works correctly, as it uses the `Dependencies` list to track the dependencies of modules for graph building purposes. This list includes the dependencies added from dependency blocks, which is handled in a different stage.
func (*TerragruntConfig) SetFieldMetadata ¶ added in v0.38.6
func (conf *TerragruntConfig) SetFieldMetadata(fieldName string, m map[string]interface{})

This preserves the order of the blocks as they appear in the config, so that we can // merge the included config in the right order. CurrentList []IncludeConfig // CurrentMap is the map version of CurrentList that maps the block labels to the included config. CurrentMap map[string]IncludeConfig // Original is used to track the original included config, and is used for resolving the include related // functions. Original *IncludeConfig }
TrackInclude is used to differentiate between an included config in the current parsing ctx, and an included config that was passed through from a previous parsing ctx.
func DecodeBaseBlocks ¶ added in v0.19.20
func DecodeBaseBlocks(ctx *ParsingContext, file *hclparse.File, includeFromChild *IncludeConfig) (*TrackInclude, *cty.Value, error)
DecodeBaseBlocks takes in a parsed HCL2 file and decodes the base blocks. Base blocks are blocks that should always be decoded even in partial decoding, because they provide bindings that are necessary for parsing any block in the file. Currently base blocks are: - locals - include
