Functions

func GetChaincodePackageBytes

func GetChaincodePackageBytes(pr *platforms.Registry, spec *pb.ChaincodeSpec) ([]byte, error)

GetChaincodePackageBytes creates bytes for docker container generation using the supplied chaincode specification

Types

type Builder

type Builder interface {
	Build() (io.Reader, error)
}

type ExitedFunc

type ExitedFunc func(exitCode int, err error)

ExitedFunc is the prototype for the function called when a container exits.

type PlatformBuilder

type PlatformBuilder struct {
	Type             string
	Path             string
	Name             string
	Version          string
	CodePackage      []byte
	PlatformRegistry *platforms.Registry
}

PlatformBuilder implements the Build interface using the platforms package GenerateDockerBuild function. XXX This is a pretty awkward spot for the builder, it should really probably be pushed into the dockercontroller, as it only builds docker images, but, doing so would require contaminating the dockercontroller package with the CDS, which is also undesirable.

func (*PlatformBuilder) Build

func (b *PlatformBuilder) Build() (io.Reader, error)

Build a tar stream based on the CDS

type StartContainerReq

type StartContainerReq struct {
	ccintf.CCID
	Builder       Builder
	Args          []string
	Env           []string
	FilesToUpload map[string][]byte
}

StartContainerReq - properties for starting a container.

func (StartContainerReq) Do

func (si StartContainerReq) Do(v VM) error

func (StartContainerReq) GetCCID

func (si StartContainerReq) GetCCID() ccintf.CCID

type StopContainerReq

type StopContainerReq struct {
	ccintf.CCID
	Timeout uint
	//by default we will kill the container after stopping
	Dontkill bool
	//by default we will remove the container after killing
	Dontremove bool
}

StopContainerReq - properties for stopping a container.

func (StopContainerReq) Do

func (si StopContainerReq) Do(v VM) error

func (StopContainerReq) GetCCID

func (si StopContainerReq) GetCCID() ccintf.CCID

type VM

type VM interface {
	Start(ccid ccintf.CCID, args []string, env []string, filesToUpload map[string][]byte, builder Builder) error
	Stop(ccid ccintf.CCID, timeout uint, dontkill bool, dontremove bool) error
	Wait(ccid ccintf.CCID) (int, error)
	HealthCheck(context.Context) error
}

VM is an abstract virtual image for supporting arbitrary virual machines

type VMCReq

type VMCReq interface {
	Do(v VM) error
	GetCCID() ccintf.CCID
}

VMCReq - all requests should implement this interface. The context should be passed and tested at each layer till we stop note that we'd stop on the first method on the stack that does not take context

type VMController

type VMController struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

VMController - manages VMs

. abstract construction of different types of VMs (we only care about Docker for now)
. manage lifecycle of VM (start with build, start, stop ...
  eventually probably need fine grained management)

func NewVMController

func NewVMController(vmProviders map[string]VMProvider) *VMController

NewVMController creates a new instance of VMController

func (*VMController) Process

func (vmc *VMController) Process(vmtype string, req VMCReq) error

type VMProvider

type VMProvider interface {
	NewVM() VM
}

type WaitContainerReq

type WaitContainerReq struct {
	CCID   ccintf.CCID
	Exited ExitedFunc
}

WaitContainerReq provides the chaincode ID of the container to wait on and a callback to call upon chaincode termination.

func (WaitContainerReq) Do

func (w WaitContainerReq) Do(v VM) error

func (WaitContainerReq) GetCCID

func (w WaitContainerReq) GetCCID() ccintf.CCID
