Constants

const ContainerType = "DOCKER"

ContainerType is the string which the docker container type is registered with the container.VMController

Types

type BuildMetrics

type BuildMetrics struct {
	ChaincodeImageBuildDuration metrics.Histogram
}

func NewBuildMetrics

func NewBuildMetrics(p metrics.Provider) *BuildMetrics

type DockerVM

type DockerVM struct {
	PeerID       string
	NetworkID    string
	BuildMetrics *BuildMetrics
	// contains filtered or unexported fields
}

DockerVM is a vm. It is identified by an image id

func NewDockerVM

func NewDockerVM(peerID, networkID string, buildMetrics *BuildMetrics) *DockerVM

NewDockerVM returns a new DockerVM instance

func (*DockerVM) GetVMName

func (vm *DockerVM) GetVMName(ccid ccintf.CCID) string

GetVMName generates the VM name from peer information. It accepts a format function parameter to allow different formatting based on the desired use of the name.

func (*DockerVM) GetVMNameForDocker

func (vm *DockerVM) GetVMNameForDocker(ccid ccintf.CCID) (string, error)

GetVMNameForDocker formats the docker image from peer information. This is needed to keep image (repository) names unique in a single host, multi-peer environment (such as a development environment). It computes the hash for the supplied image name and then appends it to the lowercase image name to ensure uniqueness.

func (*DockerVM) HealthCheck

func (vm *DockerVM) HealthCheck(ctx context.Context) error

HealthCheck checks if the DockerVM is able to communicate with the Docker daemon.

func (*DockerVM) Start

func (vm *DockerVM) Start(ccid ccintf.CCID, args, env []string, filesToUpload map[string][]byte, builder container.Builder) error

Start starts a container using a previously created docker image

func (*DockerVM) Stop

func (vm *DockerVM) Stop(ccid ccintf.CCID, timeout uint, dontkill bool, dontremove bool) error

Stop stops a running chaincode

func (*DockerVM) Wait

func (vm *DockerVM) Wait(ccid ccintf.CCID) (int, error)

Wait blocks until the container stops and returns the exit code of the container.

type Provider

type Provider struct {
	PeerID       string
	NetworkID    string
	BuildMetrics *BuildMetrics
}

Provider implements container.VMProvider

func NewProvider

func NewProvider(peerID, networkID string, metricsProvider metrics.Provider) *Provider

NewProvider creates a new instance of Provider

func (*Provider) NewVM

func (p *Provider) NewVM() container.VM

NewVM creates a new DockerVM instance
