Functions

func GetChaincodePackageBytes

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

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

func GetVMFromName

func GetVMFromName(name string) string

GetVMFromName generates the docker image from peer information given the hashcode. This is needed to keep image name's unique in a single host, multi-peer environment (such as a development environment)

func SetupTestConfig

func SetupTestConfig()

SetupTestConfig setup the config during test execution

func SetupTestLogging

func SetupTestLogging()

SetupTestLogging setup the logging during test execution

func VMCProcess

func VMCProcess(ctxt context.Context, vmtype string, req VMCReqIntf) (interface{}, error)

VMCProcess should be used as follows

. construct a context
. construct req of the right type (e.g., CreateImageReq)
. call it in a go routine
. process response in the go routing

context can be cancelled. VMCProcess will try to cancel calling functions if it can For instance docker clients api's such as BuildImage are not cancelable. In all cases VMCProcess will wait for the called go routine to return

Types

type Config

type Config struct {
}

Config the config wrapper structure

type CreateImageReq

type CreateImageReq struct {
	ID           string
	Reader       io.Reader
	AttachStdin  bool
	AttachStdout bool
	Args         []string
	Env          []string
}

CreateImageReq - properties for creating an container image

type StartImageReq

type StartImageReq struct {
	ID           string
	Args         []string
	Env          []string
	AttachStdin  bool
	AttachStdout bool
}

StartImageReq - properties for starting a container.

type StopImageReq

type StopImageReq struct {
	ID      string
	Timeout uint
	//by default we will kill the container after stopping
	Dontkill bool
	//by default we will remove the container after killing
	Dontremove bool
}

StopImageReq - properties for stopping a container.

type VM

type VM struct {
	Client *docker.Client
}

VM implemenation of VM management functionality.

func NewVM

func NewVM() (*VM, error)

NewVM creates a new VM instance.

func (*VM) BuildChaincodeContainer

func (vm *VM) BuildChaincodeContainer(spec *pb.ChaincodeSpec) ([]byte, error)

BuildChaincodeContainer builds the container for the supplied chaincode specification

func (*VM) BuildObccaContainer

func (vm *VM) BuildObccaContainer() error

BuildObccaContainer builds the image for the obcca to be used in development network

func (*VM) BuildPeerContainer

func (vm *VM) BuildPeerContainer() error

BuildPeerContainer builds the image for the Peer to be used in development network

func (*VM) GetPeerPackageBytes

func (vm *VM) GetPeerPackageBytes() (io.Reader, error)

GetPeerPackageBytes returns the gzipped tar image used for docker build of Peer

func (*VM) ListImages

func (vm *VM) ListImages(context context.Context) error

ListImages list the images available

type VMCReqIntf

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

VMCReqIntf - 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 VMCResp

type VMCResp struct {
	Err  error
	Resp interface{}
}

VMCResp - response from requests. resp field is a anon interface. It can hold any response. err should be tested first

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)
