Functions

func ParseMigrationFile

func ParseMigrationFile(filename string, source []byte) (*tfmigrate.MigrationConfig, error)

ParseMigrationFile parses a given source of migration file and returns a *tfmigrate.MigrationConfig. Note that this method does not read a file and you should pass source of config in bytes. The filename is used for error message and selecting HCL syntax (.hcl and .json).

Types

type ConfigurationFile

type ConfigurationFile struct {
	// Tfmigrate is a top-level block.
	// It must contain only one block, and multiple blocks are not allowed.
	Tfmigrate TfmigrateBlock `hcl:"tfmigrate,block"`
}

ConfigurationFile represents a file for CLI settings in HCL.

type HistoryBlock

type HistoryBlock struct {
	// Storage is a block for migration history data store.
	Storage StorageBlock `hcl:"storage,block"`
}

HistoryBlock represents a block for migration history management in HCL.

type MigrationBlock

type MigrationBlock struct {
	// Type is a type for migration.
	// Valid values are `state` and `multi_state`.
	Type string `hcl:"type,label"`
	// Name is an arbitrary name for migration.
	Name string `hcl:"name,label"`
	// Remain is a body of migration block.
	// We first decode only a block header and then decode schema depending on
	// its type label.
	Remain hcl.Body `hcl:",remain"`
}

MigrationBlock represents a migration block in HCL.

type MigrationFile

type MigrationFile struct {
	// Migration is a migration block.
	// It must contain only one block, and multiple blocks are not allowed,
	// because it's hard to re-run the file if partially failed.
	Migration MigrationBlock `hcl:"migration,block"`
}

MigrationFile represents a config for migration written in HCL.

type StorageBlock

type StorageBlock struct {
	// Type is a type for storage.
	// Valid values are as follows:
	// - mock
	// - local
	// - s3
	Type string `hcl:"type,label"`
	// Remain is a body of storage block.
	// We first decode only a block header and then decode schema depending on
	// its type label.
	Remain hcl.Body `hcl:",remain"`
}

StorageBlock represents a block for migration history data store in HCL.

type TfmigrateBlock

type TfmigrateBlock struct {
	// MigrationDir is a path to directory where migration files are stored.
	// Default to `.` (current directory).
	MigrationDir string `hcl:"migration_dir,optional"`
	// History is a block for migration history management.
	History *HistoryBlock `hcl:"history,block"`
}

TfmigrateBlock represents a block for CLI settings in HCL.

type TfmigrateConfig

type TfmigrateConfig struct {
	// MigrationDir is a path to directory where migration files are stored.
	// Default to `.` (current directory).
	MigrationDir string
	// History is a config for migration history management.
	History *history.Config
}

TfmigrateConfig is a config for top-level CLI settings. TfmigrateBlock is just used for parsing HCL and TfmigrateConfig is used for building application logic.

func LoadConfigurationFile

func LoadConfigurationFile(filename string) (*TfmigrateConfig, error)

LoadConfigurationFile is a helper function which reads and parses a given configuration file.

func NewDefaultConfig

func NewDefaultConfig() *TfmigrateConfig

NewDefaultConfig returns a new instance of TfmigrateConfig.

func ParseConfigurationFile

func ParseConfigurationFile(filename string, source []byte) (*TfmigrateConfig, error)

ParseConfigurationFile parses a given source of configuration file and returns a TfmigrateConfig. Note that this method does not read a file and you should pass source of config in bytes. The filename is used for error message and selecting HCL syntax (.hcl and .json).
