}

Events is an interface that can be used to hook interesting engine/planning events.

type Manifest struct {
	Time    time.Time              // the time this snapshot was taken.
	Magic   string                 // a magic cookie.

}

type Plan 

type Plan struct {
	// contains filtered or unexported fields
}

Plan is the output of analyzing resource graphs and contains the steps necessary to perform an infrastructure deployment. A plan can be generated out of whole cloth from a resource graph -- in the case of new deployments -- however, it can alternatively be generated by diffing two resource graphs -- in the case of updates to existing stacks (presumably more common). The plan contains step objects that can be used to drive a deployment.

func NewPlan 

func NewPlan(ctx *plugin.Context, target *Target, prev *Snapshot, source Source, analyzers []tokens.QName,
	preview bool) (*Plan, error)

NewPlan creates a new deployment plan from a resource snapshot plus a package to evaluate.

From the old and new states, it understands how to orchestrate an evaluation and analyze the resulting resources. The plan may be used to simply inspect a series of operations, or actually perform them; these operations are generated based on analysis of the old and new states. If a resource exists in new, but not old, for example, it results in a create; if it exists in both, but is different, it results in an update; and so on and so forth.

Note that a plan uses internal concurrency and parallelism in various ways, so it must be closed if for some reason a plan isn't carried out to its final conclusion. This will result in cancelation and reclamation of OS resources.

func (*Plan) Ctx 

func (p *Plan) Ctx() *plugin.Context

func (*Plan) Diag

type ProviderSource added in v0.15.0 

type ProviderSource interface {
	// GetProvider fetches the provider plugin for the given reference.
	GetProvider(ref providers.Reference) (plugin.Provider, bool)
}

A ProviderSource allows a Source to lookup provider plugins.

type ReadResourceEvent added in v0.15.0 

type ReadResourceEvent interface {
	SourceEvent

	// ID is the requested ID of this read.
	ID() resource.ID
	// Name is the requested name of this read.
	Name() tokens.QName
	// Type is type of the resource being read.

}

ReadResourceEvent is an event that asks the engine to read the state of a resource that already exists.

type ReadResult added in v0.15.0 

type ReadResult struct {
	State *resource.State
}

type ReadStep added in v0.15.0 

type ReadStep struct {
	// contains filtered or unexported fields
}

ReadStep is a step indicating that an existing resources will be "read" and projected into the Pulumi object model. Resources that are read are marked with the "External" bit which indicates to the engine that it does not own this resource's lifeycle.

A resource with a given URN can transition freely between an "external" state and a non-external state. If a URN that was previously marked "External" (i.e. was the target of a ReadStep in a previous plan) is the target of a RegisterResource in the next plan, a CreateReplacement step will be issued to indicate the transition from external to owned. If a URN that was previously not marked "External" is the target of a ReadResource in the next plan, a ReadReplacement step will be issued to indicate the transition from owned to external.

	// contains filtered or unexported fields

type Snapshot 

type Snapshot struct {
	Manifest          Manifest             // a deployment manifest of versions, checksums, and so on.
	Resources         []*resource.State    // fetches all resources and their associated states.
	PendingOperations []resource.Operation // all currently pending resource operations.
}

Snapshot is a view of a collection of resources in an stack at a point in time. It describes resources; their IDs, names, and properties; their dependencies; and more. A snapshot is a diffable entity and can be used to create or apply an infrastructure deployment plan in order to make reality match the snapshot state.

func NewSnapshot 

func NewSnapshot(manifest Manifest, resources []*resource.State, ops []resource.Operation) *Snapshot

NewSnapshot creates a snapshot from the given arguments. The resources must be in topologically sorted order. This property is not checked; for verification, please refer to the VerifyIntegrity function below.

func (*Snapshot) VerifyIntegrity 

func (snap *Snapshot) VerifyIntegrity() error

VerifyIntegrity checks a snapshot to ensure it is well-formed. Because of the cost of this operation, integrity verification is only performed on demand, and not automatically during snapshot construction.

This function verifies a number of invariants:

  1. Provider resources must be referenceable (i.e. they must have a valid URN and ID)
  2. A resource's provider must precede the resource in the resource list
  3. Parents must precede children in the resource list
  4. Dependents must precede their dependencies in the resource list
  5. For every URN in the snapshot, there must be at most one resource with that URN that is not pending deletion
  6. The magic manifest number should change every time the snapshot is mutated

type Source 

type Source interface {
	io.Closer

	// Project returns the package name of the Pulumi project we are obtaining resources from.
	Project() tokens.PackageName
	// Info returns a serializable payload that can be used to stamp snapshots for future reconciliation.
	Info() interface{}

	// Iterate begins iterating the source. Error is non-nil upon failure; otherwise, a valid iterator is returned.
	Iterate(ctx context.Context, opts Options, providers ProviderSource) (SourceIterator, error)
}

A Source can generate a new set of resources that the planner will process accordingly. 

var NullSource Source = &nullSource{}

NullSource is a singleton source that never returns any resources. This may be used in scenarios where the "new" version of the world is meant to be empty, either for testing purposes, or removal of an existing stack.

func NewErrorSource added in v0.15.1 

func NewErrorSource(project tokens.PackageName) Source

func NewEvalSource 

func NewEvalSource(plugctx *plugin.Context, runinfo *EvalRunInfo,
	defaultProviderVersions map[tokens.Package]*semver.Version, dryRun bool) Source

NewEvalSource returns a planning source that fetches resources by evaluating a package with a set of args and a confgiuration map. This evaluation is performed using the given plugin context and may optionally use the given plugin host (or the default, if this is nil). Note that closing the eval source also closes the host.

func NewFixedSource 

func NewFixedSource(ctx tokens.PackageName, steps []SourceEvent) Source

NewFixedSource returns a valid planning source that is comprised of a list of pre-computed steps.

type SourceEvent 

type SourceEvent interface {
	// contains filtered or unexported methods
}

SourceEvent is an event associated with the enumeration of a plan. It is an intent expressed by the source program, and it is the responsibility of the engine to make it so.

type SourceIterator 

type SourceIterator interface {
	io.Closer

	// Next returns the next event from the source.
	Next() (SourceEvent, error)
}

A SourceIterator enumerates the list of resources that a source has to offer and tracks associated state.

type Step 

type Step interface {
	// Apply applies or previews this step. It returns the status of the resource after the step application,
	// a function to call to signal that this step has fully completed, and an error, if one occurred while applying
	// the step.
	//
	// The returned StepCompleteFunc, if not nil, must be called after committing the results of this step into
	// the state of the deployment.
	Apply(preview bool) (resource.Status, StepCompleteFunc, error) // applies or previews this step.

	Op() StepOp           // the operation performed by this step.
	URN() resource.URN    // the resource URN (for before and after).
	Type() tokens.Type    // the type affected by this step.
	Provider() string     // the provider reference for this step.
	Old() *resource.State // the state of the resource before performing this step.
	New() *resource.State // the state of the resource after performing this step.
	Res() *resource.State // the latest state for the resource that is known (worst case, old).
	Logical() bool        // true if this step represents a logical operation in the program.
	Plan() *Plan          // the owning plan.
}

Step is a specification for a deployment operation.
