Types

type AllowedFunctionsPerContainer 

type AllowedFunctionsPerContainer string

type Archive 

type Archive struct {
	// Type defines how the package is specified: literal or URL.
	Type ArchiveType `json:"type,omitempty"`

	// Literal contents of the package. Can be used for
	// encoding packages below TODO (256KB?) size.
	Literal []byte `json:"literal,omitempty"`

	URL string `json:"url,omitempty"`

	// Checksum ensures the integrity of packages
	// refereced by URL. Ignored for literals.
	Checksum Checksum `json:"checksum,omitempty"`
}

Package contains or references a collection of source or binary files.

type ArchiveType 

type ArchiveType string

ArchiveType is either literal or URL, indicating whether the package is specified in the Archive struct or externally. 

const (
	// ArchiveTypeLiteral means the package contents are specified in the Literal field of
	// resource itself.
	ArchiveTypeLiteral ArchiveType = "literal"

	// ArchiveTypeUrl means the package contents are at the specified URL.
	ArchiveTypeUrl ArchiveType = "url"
)

type BuildStatus 

type BuildStatus string

type Builder 

type Builder struct {
	// Image for containing the language runtime.
	Image string `json:"image,omitempty"`

	// (Optional) Default build command to run for this build environment.
	Command string `json:"command,omitempty"`

	// Container allows the modification of the deployed builder
	// container using the Kubernetes Container spec. Fission overrides
	// the following fields:
	// - Name
	// - Image; set to the Builder.Image
	// - Command; set to the Builder.Command
	// - TerminationMessagePath
	// - ImagePullPolicy
	// - ReadinessProbe
	// (optional)
	Container *apiv1.Container `json:"container,omitempty"`
}

type Checksum 

type Checksum struct {
	Type ChecksumType `json:"type,omitempty"`
	Sum  string       `json:"sum,omitempty"`
}

Checksum of package contents when the contents are stored outside the Package struct. Type is the checksum algorithm; "sha256" is the only currently supported one. Sum is hex encoded.

type ChecksumType

const (
	ChecksumTypeSHA256 ChecksumType = "sha256"

	Runtime Runtime `json:"runtime"`

	// Optional
	Builder Builder `json:"builder"`

type Error 

type Error struct {
	Code    errorCode `json:"code"`
	Message string    `json:"message"`
}

Errors returned by the Fission API.

type ExecutionStrategy 

type ExecutionStrategy struct {
	ExecutorType     ExecutorType
	MinScale         int
	MaxScale         int
	TargetCPUPercent int
}

ExecutionStrategy specifies low-level parameters for function execution, 

such as the number of instances.

MinScale affects the cold start behaviour for a function. If MinScale is 0 then the
deployment is created on first invocation of function and is good for requests of
asynchronous nature. If MinScale is greater than 0 then MinScale number of pods are
created at the time of creation of function. This ensures faster response during first
invocation at the cost of consuming resources.

MaxScale is the maximum number of pods that function will scale to based on TargetCPUPercent
and resources allocated to the function pod.

	// FunctionName specifies a specific function within the package. This allows
	// functions to share packages, by having different functions within the same

	// associated with. An Environment with this name should exist, otherwise the
	// function cannot be invoked.
	Environment EnvironmentReference `json:"environment"`

	// Reference to a package containing deployment and optionally the source
	Package FunctionPackageRef `json:"package"`

	Secrets    []SecretReference    `json:"secrets"`

An InvokeStategy is of one of two types: ExecutionStrategy, which controls low-level
parameters such as which ExecutorType to use, when to autoscale, minimum and maximum
number of running instances, etc. A higher-level AbstractInvokeStrategy will also be
supported; this strategy would specify the target request rate of the function,
the target latency statistics, and the target cost (in terms of compute resources).
