func GetChaincodePackageBytes ¶

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

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

type Builder ¶

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

type ExitedFunc ¶

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

type ExitedFunc func(exitCode int, err error)

type PlatformBuilder ¶

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.

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

func (*PlatformBuilder) Build ¶

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

Build a tar stream based on the CDS

type StartContainerReq ¶

StartContainerReq - properties for starting a container.

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

func (StartContainerReq) Do ¶

func (si StartContainerReq) Do(v VM) error

func (StartContainerReq) GetCCID ¶

func (si StartContainerReq) GetCCID() ccintf.CCID

type StopContainerReq ¶

StopContainerReq - properties for stopping a container.

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
}

func (StopContainerReq) Do ¶

func (si StopContainerReq) Do(v VM) error

func (StopContainerReq) GetCCID ¶

func (si StopContainerReq) GetCCID() ccintf.CCID

type VM ¶

VM is an abstract virtual image for supporting arbitrary virtual machines

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
}

type VMCReq ¶

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

type VMController ¶

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)

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

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 ¶

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

type WaitContainerReq struct {
    CCID   ccintf.CCID
    Exited ExitedFunc
}

func (WaitContainerReq) Do ¶

func (w WaitContainerReq) Do(v VM) error

func (WaitContainerReq) GetCCID ¶

func (w WaitContainerReq) GetCCID() ccintf.CCID
