Types

type Options 

type Options struct {
	K8s            kubernetes.Interface
	NodeName       string
	PluginName     string
	PluginIdx      string
	KubeletPodsDir string
	HostPrefixDir  string
}

Options configures the Plugin.

type Plugin 

type Plugin struct {
	// contains filtered or unexported fields
}

Plugin is an NRI plugin that applies cgroupv2 io.max limits to containers whose CSI volumes carry IO limit metadata in their VolumeAttachment.

func New 

func New(opts Options) (*Plugin, error)

New creates and registers the NRI plugin stub.

func (*Plugin) CreateContainer 

func (p *Plugin) CreateContainer(ctx context.Context, pod *api.PodSandbox, container *api.Container) (*api.ContainerAdjustment, []*api.ContainerUpdate, error)

CreateContainer implements stub.CreateContainerInterface.

The returned ContainerAdjustment carries io.max entries in the cgroupv2 Unified map; the runtime writes them to the container cgroup at creation time, so we never touch the cgroup filesystem directly.

func (*Plugin) Run 

func (p *Plugin) Run(ctx context.Context) error

Run starts the informer cache, waits for it to sync, then starts the NRI plugin and blocks until ctx is cancelled or the runtime disconnects.
