ContainerType is the string which the docker container type is registered with the container.VMController
const ContainerType = "DOCKER"
type BuildMetrics struct {
ChaincodeImageBuildDuration metrics.Histogram
}
func NewBuildMetrics(p metrics.Provider) *BuildMetrics
DockerVM is a vm. It is identified by an image id
type DockerVM struct {
PeerID string
NetworkID string
BuildMetrics *BuildMetrics
// contains filtered or unexported fields
}
func NewDockerVM(peerID, networkID string, buildMetrics *BuildMetrics) *DockerVM
NewDockerVM returns a new DockerVM instance
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 (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 (vm *DockerVM) HealthCheck(ctx context.Context) error
HealthCheck checks if the DockerVM is able to communicate with the Docker daemon.
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 (vm *DockerVM) Stop(ccid ccintf.CCID, timeout uint, dontkill bool, dontremove bool) error
Stop stops a running chaincode
func (vm *DockerVM) Wait(ccid ccintf.CCID) (int, error)
Wait blocks until the container stops and returns the exit code of the container.
Provider implements container.VMProvider
type Provider struct {
PeerID string
NetworkID string
BuildMetrics *BuildMetrics
}
func NewProvider(peerID, networkID string, metricsProvider metrics.Provider) *Provider
NewProvider creates a new instance of Provider
func (p *Provider) NewVM() container.VM
NewVM creates a new DockerVM instance
