type Local

	CLIColor *colorstring.Colorize

	// ShowDiagnostics prints diagnostic messages to the UI.

	// The State* paths are set from the backend config, and may be left blank

	//
	// StateOutPath is the local path where the state will be written.
	// If this is empty, it will default to StatePath.
	//
	// StateBackupPath is the local path where a backup file will be written.
	// Set this to "-" to disable state backup.
	//

	// Backend, if non-nil, will use this backend for non-enhanced behavior.
	// This allows local behavior with remote state storage. It is a way to

}

Local is an implementation of EnhancedBackend that performs all operations locally. This is the "default" backend and implements normal Terraform behavior as it is well known.

func TestLocal

func TestLocal(t *testing.T) (*Local, func())

TestLocal returns a configured Local struct with temporary paths and in-memory ContextOpts.

No operations will be called on the returned value, so you can still set public fields without any locks.

func (*Local) CLIInit

func (b *Local) CLIInit(opts *backend.CLIOpts) error

backend.CLI impl.

func (*Local) Colorize

func (b *Local) Colorize() *colorstring.Colorize

Colorize returns the Colorize structure that can be used for colorizing output. This is gauranteed to always return a non-nil value and so is useful as a helper to wrap any potentially colored strings.

func (*Local) ConfigSchema

func (b *Local) ConfigSchema() *configschema.Block

func (*Local) Configure

func (b *Local) Configure(obj cty.Value) tfdiags.Diagnostics

func (*Local) Context

func (b *Local) Context(op *backend.Operation) (*terraform.Context, statemgr.Full, tfdiags.Diagnostics)

backend.Local implementation.

func (*Local) DeleteWorkspace

func (b *Local) DeleteWorkspace(name string) error

DeleteWorkspace removes a workspace.

The "default" workspace cannot be removed.

func (*Local) Operation

func (b *Local) Operation(ctx context.Context, op *backend.Operation) (*backend.RunningOperation, error)

Operation implements backend.Enhanced

This will initialize an in-memory terraform.Context to perform the operation within this process.

The given operation parameter will be merged with the ContextOpts on the structure with the following rules. If a rule isn't specified and the name conflicts, assume that the field is overwritten if set.

func (*Local) ReportResult

func (b *Local) ReportResult(op *backend.RunningOperation, diags tfdiags.Diagnostics)

ReportResult is a helper for the common chore of setting the status of a running operation and showing any diagnostics produced during that operation.

If the given diagnostics contains errors then the operation's result will be set to backend.OperationFailure. It will be set to backend.OperationSuccess otherwise. It will then use b.ShowDiagnostics to show the given diagnostics before returning.

Callers should feel free to do each of these operations separately in more complex cases where e.g. diagnostics are interleaved with other output, but terminating immediately after reporting error diagnostics is common and can be expressed concisely via this method.

func (*Local) StateMgr

func (b *Local) StateMgr(name string) (statemgr.Full, error)

func (*Local) StatePaths

func (b *Local) StatePaths(name string) (stateIn, stateOut, backupOut string)

StatePaths returns the StatePath, StateOutPath, and StateBackupPath as configured from the CLI.

func (*Local) ValidateConfig

func (b *Local) ValidateConfig(obj cty.Value) tfdiags.Diagnostics

func (*Local) Workspaces

func (b *Local) Workspaces() ([]string, error)

type StateHook

type StateHook struct {
	terraform.NilHook
	sync.Mutex

	StateMgr statemgr.Writer
}

StateHook is a hook that continuously updates the state by calling WriteState on a state.State.

func (*StateHook) PostStateUpdate

func (h *StateHook) PostStateUpdate(new *states.State) (terraform.HookAction, error)

type TestLocalSingleState

type TestLocalSingleState struct {
	Local
}

TestLocalSingleState is a backend implementation that wraps Local and modifies it to only support single states (returns ErrNamedStatesNotSupported for multi-state operations).

This isn't an actual use case, this is exported just to provide a easy way to test that behavior.

func (*TestLocalSingleState) DeleteState

func (b *TestLocalSingleState) DeleteState(string) error

func (*TestLocalSingleState) State

func (b *TestLocalSingleState) State(name string) (statemgr.Full, error)

func (*TestLocalSingleState) States

func (b *TestLocalSingleState) States() ([]string, error)
