Golang New Examples

Example #1

File: main.go Project: timani/garden-linux

func (p *provider) ProvideContainer(spec linux_backend.LinuxContainerSpec) linux_backend.Container {
	cgroupReader := &cgroups_manager.LinuxCgroupReader{
		Path: p.sysconfig.CgroupNodeFilePath,

	cgroupsManager := cgroups_manager.New(p.sysconfig.CgroupPath, spec.ID, cgroupReader)

	oomWatcher := linux_container.NewOomNotifier(
		p.runner, spec.ContainerPath, cgroupsManager,
	)

	return linux_container.NewLinuxContainer(
