Overview ¶
Package containerdutil provides "caching" versions of containerd native snapshotter and content store. NOTE: caching should only be used for single, atomic operations, like `nerdctl images`, and NOT kept across successive, distincts operations. As such, caching is not persistent across invocations of nerdctl, and only lasts as long as the lifetime of the Snapshotter or ContentStore.

Functions ¶
func NewProvider ¶
func NewProvider(client *containerd.Client) content.Provider
ContentStore should be called to get a Provider with caching
func ServerSemVer ¶
func SnapshotService ¶
func SnapshotService(client *containerd.Client, snapshotterName string) snapshots.Snapshotter
SnapshotService should be called to get a new caching snapshotter
func SupportsFullTransferService ¶
func SupportsFullTransferService(ctx context.Context, client *containerd.Client) bool
SupportsFullTransferService checks if the containerd version fully supports the Transfer service. While containerd 1.7 has Transfer service, full support is only available in 2.0+. The following features are missing in containerd 1.7:
- Non-distributable artifacts support
- Registry configuration options: WithHostDir(), WithDefaultScheme() etc.
Types ¶
type ImageStore ¶ added in v2.0.5
type ImageStore struct {
}
