Functions ¶

func MakeClient ¶

func MakeClient(ctx context.Context, config coretypes.Config, nodename, endpoint string) (engine.API, error)

MakeClient builds a containerd engine for endpoint.

Types ¶

type Engine ¶

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

Engine runs containers through a node's own containerd socket, forwarded over SSH.

func (*Engine) BuildContent ¶

func (e *Engine) BuildContent(ctx context.Context, scm coresource.Source, opts *enginetypes.BuildContentOptions) (string, io.Reader, error)

BuildContent renders the build spec into a Dockerfile and tars the context around it.

func (*Engine) BuildRefs ¶

func (e *Engine) BuildRefs(_ context.Context, opts *enginetypes.BuildRefOptions) []string

func (*Engine) CloseConn ¶

func (e *Engine) CloseConn() error

func (*Engine) ExecExitCode ¶

func (e *Engine) ExecExitCode(_ context.Context, _, execID string) (int, error)

func (*Engine) ExecResize ¶

func (e *Engine) ExecResize(_ context.Context, execID string, height, width uint) error

func (*Engine) Execute ¶

func (e *Engine) Execute(ctx context.Context, ID string, config *enginetypes.ExecConfig) (execID string, stdout, stderr io.ReadCloser, stdin io.WriteCloser, err error)

func (*Engine) GetParams ¶

func (e *Engine) GetParams() *enginetypes.Params

func (*Engine) ImageBuild ¶

func (e *Engine) ImageBuild(ctx context.Context, input io.Reader, refs []string, platform string) (_ io.ReadCloser, err error)

ImageBuild solves the context on the node's buildkitd and exports straight to the registry.

func (*Engine) ImageBuildCachePrune ¶

func (e *Engine) ImageBuildCachePrune(ctx context.Context, all bool) (uint64, error)

func (*Engine) ImageBuildFromExist ¶

func (e *Engine) ImageBuildFromExist(ctx context.Context, ID string, refs []string, _ string) (string, error)

ImageBuildFromExist captures the workload's writable snapshot as one more layer on its image.

func (*Engine) ImageList ¶

func (e *Engine) ImageList(ctx context.Context, image string) ([]*enginetypes.Image, error)

func (*Engine) ImageLocalDigests ¶

func (e *Engine) ImageLocalDigests(ctx context.Context, image string) ([]string, error)

func (*Engine) ImagePull ¶

func (e *Engine) ImagePull(ctx context.Context, ref string, _ bool) (io.ReadCloser, error)

func (*Engine) ImagePush ¶

func (e *Engine) ImagePush(ctx context.Context, ref string) (io.ReadCloser, error)

ImagePush has nothing to send after a solve: BuildKit's exporter already pushed the image.

func (*Engine) ImageRemoteDigest ¶

func (e *Engine) ImageRemoteDigest(ctx context.Context, image string) (string, error)

func (*Engine) ImageRemove ¶

func (e *Engine) ImageRemove(ctx context.Context, image string, _, _ bool) ([]string, error)

func (*Engine) ImagesPrune ¶

func (e *Engine) ImagesPrune(ctx context.Context) error

ImagesPrune drops every image no container is built on; containerd collects the blobs itself.

func (*Engine) Info ¶

func (e *Engine) Info(ctx context.Context) (*enginetypes.Info, error)

func (*Engine) NetworkConnect ¶

func (e *Engine) NetworkConnect(context.Context, string, string, string, string) ([]string, error)

NetworkConnect is not a CNI operation: a network is attached when the netns is created.

func (*Engine) NetworkDisconnect ¶

func (e *Engine) NetworkDisconnect(context.Context, string, string, bool) error

func (*Engine) NetworkList ¶

func (e *Engine) NetworkList(ctx context.Context, drivers []string) ([]*enginetypes.Network, error)

func (*Engine) Ping ¶

func (e *Engine) Ping(ctx context.Context) error

func (*Engine) RawEngine ¶

func (e *Engine) RawEngine(context.Context, *enginetypes.RawEngineOptions) (*enginetypes.RawEngineResult, error)

func (*Engine) VerifyNode ¶

func (e *Engine) VerifyNode(ctx context.Context) error

func (*Engine) VirtualizationAttach ¶

func (e *Engine) VirtualizationAttach(ctx context.Context, ID string, _, stdin bool) (io.ReadCloser, io.ReadCloser, io.WriteCloser, error)

VirtualizationAttach without stdin is the journald follow; with stdin it is the fifo relays.

func (*Engine) VirtualizationCopyChunkTo ¶

func (e *Engine) VirtualizationCopyChunkTo(ctx context.Context, ID, target string, size int64, content io.Reader, uid, gid int, mode int64) error

func (*Engine) VirtualizationCopyFrom ¶

func (e *Engine) VirtualizationCopyFrom(ctx context.Context, ID, path string) (content []byte, uid, gid int, mode int64, err error)

func (*Engine) VirtualizationCreate ¶

func (e *Engine) VirtualizationCreate(ctx context.Context, opts *enginetypes.VirtualizationCreateOptions) (*enginetypes.VirtualizationCreated, error)

func (*Engine) VirtualizationInspect ¶

func (e *Engine) VirtualizationInspect(ctx context.Context, ID string) (*enginetypes.VirtualizationInfo, error)

func (*Engine) VirtualizationLogs ¶

func (e *Engine) VirtualizationLogs(ctx context.Context, opts *enginetypes.VirtualizationLogStreamOptions) (stdout, stderr io.ReadCloser, err error)

func (*Engine) VirtualizationRemove ¶

func (e *Engine) VirtualizationRemove(ctx context.Context, ID string, _, force bool) error

func (*Engine) VirtualizationResize ¶

func (e *Engine) VirtualizationResize(context.Context, string, uint, uint) error

VirtualizationResize has nothing to resize: a workload's stdio is a pipe, never a terminal.

func (*Engine) VirtualizationResume ¶

func (e *Engine) VirtualizationResume(ctx context.Context, ID string) error

func (*Engine) VirtualizationStart ¶

func (e *Engine) VirtualizationStart(ctx context.Context, ID string) (err error)

func (*Engine) VirtualizationStop ¶

func (e *Engine) VirtualizationStop(ctx context.Context, ID string, gracefulTimeout time.Duration) (err error)

func (*Engine) VirtualizationSuspend ¶

func (e *Engine) VirtualizationSuspend(ctx context.Context, ID string) error

func (*Engine) VirtualizationUpdateResource ¶

func (e *Engine) VirtualizationUpdateResource(ctx context.Context, ID string, engineParams resourcetypes.Resources) error

func (*Engine) VirtualizationWait ¶

func (e *Engine) VirtualizationWait(ctx context.Context, ID, _ string) (*enginetypes.VirtualizationWaitResult, error)

type RawArgs ¶

type RawArgs struct {
	CapAdd  []string        `json:"cap_add"`
	CapDrop []string        `json:"cap_drop"`
	Devices []string        `json:"devices"` // host[:container[:perms]]
	Ulimits []*units.Ulimit `json:"ulimits"`
	Runtime string          `json:"runtime"`
	PidsMax int64           `json:"pids_max"` // cgroup v2 pids.max
}

RawArgs carries containerd-specific workload options through core untouched.
