stack

Documentation

Overview

Package stack contains the serialized and configurable state associated with an stack; or, in other words, a deployment target. It pertains to resources and deployment plans, but is a package unto itself.

Constants

const (
	// DeploymentSchemaVersionOldestSupported is the oldest deployment schema that we
	// still support, i.e. we can produce a `deploy.Snapshot` from. This will generally
	// need to be at least one less than the current schema version so that old deployments can
	// be migrated to the current schema.
	DeploymentSchemaVersionOldestSupported = 1
)

Variables

	// untyped deployment being deserialized is too old to understand.
	ErrDeploymentSchemaVersionTooOld = fmt.Errorf("this stack's deployment is too old")

Functions

func DeserializeCheckpoint

func DeserializeCheckpoint(chkpoint *apitype.CheckpointV3) (*deploy.Snapshot, error)

DeserializeCheckpoint takes a serialized deployment record and returns its associated snapshot. Returns nil if there have been no deployments performed on this checkpoint.

func DeserializeDeploymentV3

func DeserializeDeploymentV3(deployment apitype.DeploymentV3) (*deploy.Snapshot, error)

DeserializeDeploymentV3 deserializes a typed DeploymentV3 into a `deploy.Snapshot`.

func DeserializeOperation

func DeserializeOperation(op apitype.OperationV2) (resource.Operation, error)

func DeserializeProperties

func DeserializeProperties(props map[string]interface{}) (resource.PropertyMap, error)

DeserializeProperties deserializes an entire map of deploy properties into a resource property map.

func DeserializePropertyValue

func DeserializePropertyValue(v interface{}) (resource.PropertyValue, error)

DeserializePropertyValue deserializes a single deploy property into a resource property value.

func DeserializeResource

func DeserializeResource(res apitype.ResourceV3) (*resource.State, error)

DeserializeResource turns a serialized resource back into its usual form.

func DeserializeUntypedDeployment

func DeserializeUntypedDeployment(deployment *apitype.UntypedDeployment) (*deploy.Snapshot, error)

DeserializeUntypedDeployment deserializes an untyped deployment and produces a `deploy.Snapshot` from it. DeserializeDeployment will return an error if the untyped deployment's version is not within the range `DeploymentSchemaVersionCurrent` and `DeploymentSchemaVersionOldestSupported`.

func GetRootStackResource

func GetRootStackResource(snap *deploy.Snapshot) (*resource.State, map[string]interface{})

GetRootStackResource returns the root stack resource from a given snapshot, or nil if not found. If the stack exists, its output properties, if any, are also returned in the resulting map.

func SerializeCheckpoint

func SerializeCheckpoint(stack tokens.QName, config config.Map, snap *deploy.Snapshot) *apitype.VersionedCheckpoint

SerializeCheckpoint turns a snapshot into a data structure suitable for serialization.

func SerializeDeployment

func SerializeDeployment(snap *deploy.Snapshot) *apitype.DeploymentV3

SerializeDeployment serializes an entire snapshot as a deploy record.

func SerializeOperation

func SerializeOperation(op resource.Operation) apitype.OperationV2

func SerializeProperties

func SerializeProperties(props resource.PropertyMap) map[string]interface{}

SerializeProperties serializes a resource property bag so that it's suitable for serialization.

func SerializePropertyValue

func SerializePropertyValue(prop resource.PropertyValue) interface{}

SerializePropertyValue serializes a resource property value so that it's suitable for serialization.

func SerializeResource

func SerializeResource(res *resource.State) apitype.ResourceV3

SerializeResource turns a resource into a structure suitable for serialization.

func UnmarshalVersionedCheckpointToLatestCheckpoint

func UnmarshalVersionedCheckpointToLatestCheckpoint(bytes []byte) (*apitype.CheckpointV3, error)
