Constants

const DEFAULT_PATH_TO_LOCAL_STATE_FILE = "terraform.tfstate"

When storing Terraform state locally, this is the default path to the tfstate file

const DEFAULT_PATH_TO_REMOTE_STATE_FILE = ".terraform/terraform.tfstate"

When using remote state storage, Terraform keeps a local copy of the state file in this folder

const MAX_RETRIES_WAITING_FOR_S3_BUCKET = 12

const SLEEP_BETWEEN_RETRIES_WAITING_FOR_S3_BUCKET = 5 * time.Second

Variables

var RemoteBackendMissing = fmt.Errorf("The remote_state.backend field cannot be empty")

Functions

func CreateS3Bucket

func CreateS3Bucket(s3Client *s3.S3, config *RemoteStateConfigS3, terragruntOptions *options.TerragruntOptions) error

Create the S3 bucket specified in the given config

func CreateS3BucketWithVersioning

func CreateS3BucketWithVersioning(s3Client *s3.S3, config *RemoteStateConfigS3, terragruntOptions *options.TerragruntOptions) error

Create the given S3 bucket and enable versioning for it

func CreateS3Client

func CreateS3Client(awsRegion, awsProfile string) (*s3.S3, error)

Create an authenticated client for DynamoDB

func DoesS3BucketExist

func DoesS3BucketExist(s3Client *s3.S3, config *RemoteStateConfigS3) bool

Returns true if the S3 bucket specified in the given config exists and the current user has the ability to access it.

func EnableVersioningForS3Bucket

func EnableVersioningForS3Bucket(s3Client *s3.S3, config *RemoteStateConfigS3, terragruntOptions *options.TerragruntOptions) error

Enable versioning for the S3 bucket specified in the given config

func InitializeRemoteStateS3

func InitializeRemoteStateS3(config map[string]interface{}, terragruntOptions *options.TerragruntOptions) error

Initialize the remote state S3 bucket specified in the given config. This function will validate the config parameters, create the S3 bucket if it doesn't already exist, and check that versioning is enabled.

func WaitUntilS3BucketExists

func WaitUntilS3BucketExists(s3Client *s3.S3, config *RemoteStateConfigS3, terragruntOptions *options.TerragruntOptions) error

AWS is eventually consistent, so after creating an S3 bucket, this method can be used to wait until the information about that S3 bucket has propagated everywhere

Types

type CantParseTerraformStateFile

type CantParseTerraformStateFile struct {
	Path          string
	UnderlyingErr error
}

func (CantParseTerraformStateFile) Error

func (err CantParseTerraformStateFile) Error() string

type MaxRetriesWaitingForS3BucketExceeded

type MaxRetriesWaitingForS3BucketExceeded string

func (MaxRetriesWaitingForS3BucketExceeded) Error

func (err MaxRetriesWaitingForS3BucketExceeded) Error() string

type MissingRequiredS3RemoteStateConfig

type MissingRequiredS3RemoteStateConfig string

func (MissingRequiredS3RemoteStateConfig) Error

func (configName MissingRequiredS3RemoteStateConfig) Error() string

type RemoteState

type RemoteState struct {
	Backend string                 `hcl:"backend"`

Configuration for Terraform remote state

func (RemoteState) ConfigureRemoteState

func (remoteState RemoteState) ConfigureRemoteState(terragruntOptions *options.TerragruntOptions) error

Configure Terraform remote state

func (*RemoteState) FillDefaults

func (remoteState *RemoteState) FillDefaults()

Fill in any default configuration for remote state

func (*RemoteState) Initialize

func (remoteState *RemoteState) Initialize(terragruntOptions *options.TerragruntOptions) error

Perform any actions necessary to initialize the remote state before it's used for storage. For example, if you're using S3 for remote state storage, this may create the S3 bucket if it doesn't exist already.

func (*RemoteState) String

func (state *RemoteState) String() string

func (RemoteState) ToTerraformInitArgs

func (remoteState RemoteState) ToTerraformInitArgs() []string

Convert the RemoteState config into the format used by the terraform init command

func (remoteState *RemoteState) Validate() error

Validate that the remote state is configured correctly
