Types

type Dialer

type Dialer struct {
	// Dial is a function used to establish a network connection to a remote snapshotter.
	Dial func(context.Context, string) (net.Conn, error)

	// Timeout is the time required to establish a connection to a remote snapshotter.
	Timeout time.Duration
}

Dialer captures commonly grouped dial functionality and configuration.

type RemoteSnapshotter

type RemoteSnapshotter struct {
	snapshots.Snapshotter
	// contains filtered or unexported fields
}

RemoteSnapshotter embeds a snapshots.Snapshotter and its metrics proxy.

func NewRemoteSnapshotter

func NewRemoteSnapshotter(ctx context.Context, address string,
	dialer func(context.Context, string) (net.Conn, error), metricsProxy *metrics.Proxy) (*RemoteSnapshotter, error)

NewRemoteSnapshotter creates a proxy snapshotter using gRPC over vsock connection.

func (*RemoteSnapshotter) Cleanup

func (rs *RemoteSnapshotter) Cleanup(ctx context.Context) error

Cleanup implements the Cleaner interface for snapshotters. This enables asynchronous resource cleanup by remote snapshotters.

See https://github.com/containerd/containerd/blob/v1.6.4/snapshots/snapshotter.go

func (*RemoteSnapshotter) Close

func (rs *RemoteSnapshotter) Close() error

Close closes the remote snapshotter's snapshotter and shuts down its metrics proxy server.

func (*RemoteSnapshotter) MetricsProxyLabels

func (rs *RemoteSnapshotter) MetricsProxyLabels() map[string]string

MetricsProxyLabels returns the metrics labels for a remote snapshotter.

func (*RemoteSnapshotter) MetricsProxyPort

func (rs *RemoteSnapshotter) MetricsProxyPort() int

MetricsProxyPort returns the metrics proxy port for a remote snapshotter.
