TestScenario1HTTPThreeServicesInSequence is a basic test setup with a few services calling each other in a chain over http. Similar to the original bookinfo example setup.

func TestScenario2ThreeServicesInSequenceDeploymentConfig

func TestScenario2ThreeServicesInSequenceDeploymentConfig(out io.Writer)

TestScenario2ThreeServicesInSequenceDeploymentConfig is a basic test setup with a few services calling each other in a chain. Similar to the original bookinfo example setup. Using DeploymentConfig.

func VirtualService

func VirtualService(service Entry) runtime.Object

VirtualService basic SubGenerator for the kind VirtualService.

Types

type Entry

type Entry struct {
	Name           string
	DeploymentType string
	Namespace      string
}

Entry is a simple value object that holds the basic configuration used by the generator.

func (*Entry) HostName

func (e *Entry) HostName() string

HostName return the full cluster host name if Namespace is set or the local if not.

type Modifier

type Modifier func(service Entry, object runtime.Object)

Modifier is a function to change a runtime.Object into something more specific for a given scenario.

func Call

func Call(proto Protocol, target Entry) Modifier

Call modifier to have the test service call another. Combine with ForService.

func ConnectToGateway

func ConnectToGateway(hostname string) Modifier

ConnectToGateway modifier to connect VirtualService to a Gateway. Combine with ForService.

func ForService

func ForService(target Entry, modifiers ...Modifier) Modifier

ForService modifier is a filter to only execute the given modifiers if the target object belongs to the named target.

func GatewayOnHost

func GatewayOnHost(hostname string) Modifier

GatewayOnHost modifier to set a hostname on the gateway.

func WithVersion

func WithVersion(version string) Modifier

WithVersion modifier adds a single istio 'version' to DestinationRule/VirtualService/Deployment.

type Protocol

type Protocol func(target Entry) string

Protocol is a function that returns the URL for a given Protocol for a given Service.

func GRPC

func GRPC() Protocol

GRPC returns the GRPC URL for the given target.

func HTTP

func HTTP() Protocol

HTTP returns the HTTP URL for the given target.

type SubGenerator

type SubGenerator func(service Entry) runtime.Object

SubGenerator is a function intended to create the basic runtime.Object as a starting point for modification.
