Types

type Context 

type Context struct {
	Cancel          *cancel.Context
	Events          chan<- Event
	SnapshotManager SnapshotManager
	BackendClient   deploy.BackendClient
	ParentSpan      opentracing.SpanContext
}

Context provides cancellation, termination, and eventing options for an engine operation. It also provides a way for the engine to persist snapshots, using the `SnapshotManager`.

type DecryptError added in v0.15.1 

type DecryptError struct {
	Key config.Key // The configuration key whose value couldn't be decrypted
	Err error      // The error that occurred while decrypting
}

DecryptError is the type of errors that arise when the engine can't decrypt a configuration key. The most common reason why this happens is that this key is being decrypted in a stack that's not the same one that encrypted it.

func (DecryptError) Error added in v0.15.1 

func (d DecryptError) Error() string

type DiagEventPayload 

type DiagEventPayload struct {
	URN       resource.URN
	Prefix    string
	Message   string
	Color     colors.Colorization
	Severity  diag.Severity
	StreamID  int32
	Ephemeral bool
}

DiagEventPayload is the payload for an event with type `diag`

type Event 

type Event struct {
	Type    EventType
	Payload interface{}
}

Event represents an event generated by the engine during an operation. The underlying type for the `Payload` field will differ depending on the value of the `Type` field

type EventType 

type EventType string

EventType is the kind of event being emitted. 

const (
	CancelEvent             EventType = "cancel"
	StdoutColorEvent        EventType = "stdoutcolor"
	DiagEvent               EventType = "diag"
	PreludeEvent            EventType = "prelude"
	SummaryEvent            EventType = "summary"
	ResourcePreEvent        EventType = "resource-pre"
	ResourceOutputsEvent    EventType = "resource-outputs"
	ResourceOperationFailed EventType = "resource-operationfailed"
)

type PreludeEventPayload 

type PreludeEventPayload struct {
	IsPreview bool              // true if this prelude is for a plan operation
	Config    map[string]string // the keys and values for config. For encrypted config, the values may be blinded
}

type Projinfo 

type Projinfo struct {
	Proj *workspace.Project
	Root string
}

func (*Projinfo) GetPwdMain 

func (projinfo *Projinfo) GetPwdMain() (string, string, error)

GetPwdMain returns the working directory and main entrypoint to use for this package.

ResourceChanges contains the aggregate resource changes by operation type.

func Destroy 

func Destroy(u UpdateInfo, ctx *Context, opts UpdateOptions, dryRun bool) (ResourceChanges, error)

func Refresh 

func Refresh(u UpdateInfo, ctx *Context, opts UpdateOptions, dryRun bool) (ResourceChanges, error)

func Update 

func Update(u UpdateInfo, ctx *Context, opts UpdateOptions, dryRun bool) (ResourceChanges, error)

func (ResourceChanges) HasChanges 

func (changes ResourceChanges) HasChanges() bool

HasChanges returns true if there are any non-same changes in the resulting summary.

type ResourceOperationFailedPayload 

type ResourceOperationFailedPayload struct {
	Metadata StepEventMetadata
	Status   resource.Status
	Steps    int
}

type ResourceOutputsEventPayload 

type ResourceOutputsEventPayload struct {
	Metadata StepEventMetadata
	Planning bool
	Debug    bool
}

type ResourcePreEventPayload 

type ResourcePreEventPayload struct {
	Metadata StepEventMetadata
	Planning bool
	Debug    bool
}

type SnapshotManager 

type SnapshotManager interface {
	io.Closer

	// BeginMutation signals to the SnapshotManager that the planner intends to mutate the global
	// snapshot. It provides the step that it intends to execute. Based on that step, BeginMutation
	// will record this intent in the global snapshot and return a `SnapshotMutation` that, when ended,
	// will complete the transaction.
	BeginMutation(step deploy.Step) (SnapshotMutation, error)

	// RegisterResourceOutputs registers the set of resource outputs generated by performing the
	// given step. These outputs are persisted in the snapshot.
	RegisterResourceOutputs(step deploy.Step) error

	// RecordPlugin records that the current plan loaded a plugin and saves it in the snapshot.
	RecordPlugin(plugin workspace.PluginInfo) error
}

SnapshotManager is responsible for maintaining the in-memory representation of the current state of the resource world.

type SnapshotMutation 

type SnapshotMutation interface {
	// End terminates the transaction and commits the results to the snapshot, returning an error if this
	// failed to complete.
	End(step deploy.Step, successful bool) error
}

SnapshotMutation represents an outstanding mutation that is yet to be completed. When the engine completes a mutation, it must call `End` in order to record the successful completion of the mutation.

type StdoutEventPayload 

type StdoutEventPayload struct {
	Message string
	Color   colors.Colorization
}

type StepEventMetadata 

type StepEventMetadata struct {
	Op       deploy.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.
	Old      *StepEventStateMetadata // the state of the resource before performing this step.
	New      *StepEventStateMetadata // the state of the resource after performing this step.
	Res      *StepEventStateMetadata // the latest state for the resource that is known (worst case, old).
	Keys     []resource.PropertyKey  // the keys causing replacement (only for CreateStep and ReplaceStep).
	Diffs    []resource.PropertyKey  // the keys causing diffs
	Logical  bool                    // true if this step represents a logical operation in the program.
	Provider string                  // the provider that performed this step.
}

type StepEventStateMetadata 

type StepEventStateMetadata struct {
	// the resource's type.
	Type tokens.Type
	// the resource's object urn, a human-friendly, unique name for the resource.
	URN resource.URN
	// true if the resource is custom, managed by a plugin.
	Custom bool
	// true if this resource is pending deletion due to a replacement.
	Delete bool
	// the resource's unique ID, assigned by the resource provider (or blank if none/uncreated).
	ID resource.ID
	// an optional parent URN that this resource belongs to.
	Parent resource.URN
	// true to "protect" this resource (protected resources cannot be deleted).
	Protect bool
	// the resource's input properties (as specified by the program). Note: because this will cross
	// over rpc boundaries it will be slightly different than the Inputs found in resource_state.
	// Specifically, secrets will have been filtered out, and large values (like assets) will be
	// have a simple hash-based representation.  This allows clients to display this information
	// properly, without worrying about leaking sensitive data, and without having to transmit huge
	// amounts of data.
	Inputs resource.PropertyMap
	// the resource's complete output state (as returned by the resource provider).  See "Inputs"
	// for additional details about how data will be transformed before going into this map.
	Outputs resource.PropertyMap
	// the resource's provider reference
	Provider string
	// InitErrors is the set of errors encountered in the process of initializing resource (i.e.,
	// during create or update).
	InitErrors []string
}

type SummaryEventPayload 

type SummaryEventPayload struct {
	IsPreview       bool            // true if this summary is for a plan operation
	MaybeCorrupt    bool            // true if one or more resources may be corrupt
	Duration        time.Duration   // the duration of the entire update operation (zero values for previews)
	ResourceChanges ResourceChanges // count of changed resources, useful for reporting
}

type UpdateInfo 

type UpdateInfo interface {
	// GetRoot returns the root directory for this update. This defines the scope for any filesystem resources
	// accessed by this update.
	GetRoot() string
	// GetProject returns information about the project associated with this update. This includes information such as
	// the runtime that will be used to execute the Pulumi program and the program's relative working directory.
	GetProject() *workspace.Project
	// GetTarget returns information about the target of this update. This includes the name of the stack being
	// updated, the configuration values associated with the target and the target's latest snapshot.
	GetTarget() *deploy.Target
}

UpdateInfo abstracts away information about an apply, preview, or destroy.

type UpdateOptions 

type UpdateOptions struct {
	// an optional set of analyzers to run as part of this deployment.
	Analyzers []string

	// the degree of parallelism for resource operations (<=1 for serial).
	Parallel int

	// true if debugging output it enabled
	Debug bool

	// true if the plan should refresh before executing.
	Refresh bool
	// contains filtered or unexported fields
}

UpdateOptions contains all the settings for customizing how an update (deploy, preview, or destroy) is performed.

This structre is embedded in another which uses some of the unexported fields, which trips up the `structcheck` linter. nolint: structcheck
