Struct DockerBackend 

pub struct DockerBackend { /* private fields */ }

Docker-based VM backend.

Each VM is a long-lived container; snapshots are committed images.

Implementations

impl DockerBackend

pub fn connect() -> Result<Self>

Connect to the local Docker daemon.

Errors

Returns an error if bollard cannot resolve a Docker endpoint.

Trait Implementations

impl Debug for DockerBackend

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl VmBackend for DockerBackend

fn create<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, image: &'life1 str, _config: &'life2 VmConfig, ) -> Pin<Box<dyn Future<Output = Result<Box<dyn Vm>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Boot a new VM from the given OCI image reference.

fn restore<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, snapshot: &'life1 SnapshotId, _config: &'life2 VmConfig, ) -> Pin<Box<dyn Future<Output = Result<Box<dyn Vm>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Restore a VM from a previously taken snapshot.

fn snapshot_exists<'life0, 'life1, 'async_trait>( &'life0 self, snapshot: &'life1 SnapshotId, ) -> Pin<Box<dyn Future<Output = Result<bool>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Check whether a snapshot exists in the backend store.

fn remove_snapshot<'life0, 'life1, 'async_trait>( &'life0 self, snapshot: &'life1 SnapshotId, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,
