Overview

Package daemon implements the kukeond process: it owns a controller.Exec, exposes the kukeonv1 API over a unix socket using net/rpc + jsonrpc, and manages its own lifecycle (listener, PID file, graceful shutdown).

type KukeonV1Service 

type KukeonV1Service struct {
	// contains filtered or unexported fields
}

KukeonV1Service implements the net/rpc server methods for the KukeonV1 service. Each method always returns nil to net/rpc and carries structured errors inside the Reply envelope so errdefs sentinels survive the wire.

func NewKukeonV1Service 

func NewKukeonV1Service(
	ctx context.Context,
	logger *slog.Logger,
	core kukeonv1.Client,
) *KukeonV1Service

NewKukeonV1Service constructs a service bound to the given kukeon Client. The service borrows the client; the caller owns its lifecycle.

func (*KukeonV1Service) ApplyDocuments 

func (s *KukeonV1Service) ApplyDocuments(args *kukeonv1.ApplyDocumentsArgs, reply *kukeonv1.ApplyDocumentsReply) error

func (*KukeonV1Service) AttachContainer added in v0.2.0 

func (s *KukeonV1Service) AttachContainer(
	args *kukeonv1.AttachContainerArgs,
	reply *kukeonv1.AttachContainerReply,
) error

AttachContainer is the placeholder endpoint shipped in #57. It enforces the Attachable gate at the API boundary; the full client lands in #66.

func (*KukeonV1Service) CreateCell 

func (s *KukeonV1Service) CreateCell(args *kukeonv1.CreateCellArgs, reply *kukeonv1.CreateCellReply) error

CreateCell is the net/rpc method for KukeonV1.CreateCell. net/rpc requires exported pointer-to-struct args and reply plus a single error return.

Cells created with Spec.AutoDelete=true (`kuke run --rm`) are not followed by a per-cell watcher goroutine — the daemon's reconcile loop observes the root task exit on a subsequent tick and runs the kill+delete sequence. That makes AutoDelete cleanup restart-resilient: a cell whose Spec.AutoDelete=true survives a daemon restart still gets cleaned up after the daemon is back, without per-cell startup wiring.

func (*KukeonV1Service) CreateConfig added in v0.6.0 

func (s *KukeonV1Service) CreateConfig(args *kukeonv1.CreateConfigArgs, reply *kukeonv1.CreateConfigReply) error

func (s *KukeonV1Service) ListStacks(args *kukeonv1.ListStacksArgs, reply *kukeonv1.ListStacksReply) error

func (*KukeonV1Service) LogContainer added in v0.3.0 

func (s *KukeonV1Service) LogContainer(
	args *kukeonv1.LogContainerArgs,
	reply *kukeonv1.LogContainerReply,
) error

LogContainer enforces the Attachable gate at the API boundary and returns the host path of the per-container sbsh capture file. Bytes never traverse this RPC — the client tails HostCapturePath directly.

func (*KukeonV1Service) MaterializeCell added in v0.6.0 

func (s *KukeonV1Service) MaterializeCell(
	args *kukeonv1.MaterializeCellArgs,
	reply *kukeonv1.MaterializeCellReply,
) error

MaterializeCell is the net/rpc method for KukeonV1.MaterializeCell (#818). Mirrors CreateCell, but the daemon-side controller skips the StartCell step so the resulting cell is left in a stopped state — the substrate for `kuke create cell --from-blueprint` / `--from-config` scaffolding.

func (*KukeonV1Service) Ping 

func (s *KukeonV1Service) Ping(_ *kukeonv1.PingArgs, reply *kukeonv1.PingReply) error

Ping acks that the kukeonv1 RPC handler is serving and reports the daemon build version. Used by `kuke init` to wait until kukeond is ready.

func (*KukeonV1Service) PurgeCell 

func (s *KukeonV1Service) PurgeCell(args *kukeonv1.PurgeCellArgs, reply *kukeonv1.PurgeCellReply) error

func (*KukeonV1Service) PurgeRealm 

func (s *KukeonV1Service) PurgeRealm(args *kukeonv1.PurgeRealmArgs, reply *kukeonv1.PurgeRealmReply) error

func (*KukeonV1Service) PurgeSpace 

func (s *KukeonV1Service) PurgeSpace(args *kukeonv1.PurgeSpaceArgs, reply *kukeonv1.PurgeSpaceReply) error

func (*KukeonV1Service) PurgeStack 

func (s *KukeonV1Service) PurgeStack(args *kukeonv1.PurgeStackArgs, reply *kukeonv1.PurgeStackReply) error

func (*KukeonV1Service) RefreshAll 

func (s *KukeonV1Service) RefreshAll(_ *kukeonv1.RefreshAllArgs, reply *kukeonv1.RefreshAllReply) error

func (*KukeonV1Service) StartCell 

func (s *KukeonV1Service) StartCell(args *kukeonv1.StartCellArgs, reply *kukeonv1.StartCellReply) error

func (*KukeonV1Service) StopCell 

func (s *KukeonV1Service) StopCell(args *kukeonv1.StopCellArgs, reply *kukeonv1.StopCellReply) error

type Options 

type Options struct {
	// SocketPath is the unix socket path the daemon listens on.
	SocketPath string
	// SocketMode is the file mode applied to the socket after creation.
	SocketMode os.FileMode
	// SocketGID, when non-zero, is the group the listener socket is chowned
	// to (uid stays root) so non-root members of that group can dial the
	// daemon. Set by `kuke init` to the kukeon GID. Each Serve re-applies
	// this so a daemon restart does not lose group access.
	SocketGID int
	// PIDFile, when non-empty, is written on Serve and removed on Stop.
	PIDFile string
	// ReconcileInterval is the period of the background cell-reconciliation
	// loop. Zero or negative disables the loop — useful for tests and for
	// operators who explicitly opt out via `--reconcile-interval 0`.
	ReconcileInterval time.Duration
	// Controller is forwarded to controller.NewControllerExec.
	Controller controller.Options
}

Options configures a Server.

type Server 

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

Server hosts the kukeonv1 API over JSON-RPC on a unix socket.

func NewServer 

func NewServer(ctx context.Context, logger *slog.Logger, opts Options) *Server

NewServer constructs a Server. It does not open the listener; call Serve.

func (*Server) Serve 

func (s *Server) Serve() error

Serve opens the listener and accepts connections until Stop is called or the context is cancelled. Returns nil on graceful shutdown.

func (*Server) Stop 

func (s *Server) Stop() error

Stop closes the listener, releases the controller, and removes the socket and PID file. Safe to call multiple times.
