func (Manager) AddNode ¶

func (m Manager) AddNode(ctx context.Context, nodename string, opts resourcetypes.Resources, nodeInfo *enginetypes.Info) (resourcetypes.Resources, error)

func (*Manager) AddPlugins ¶

func (m *Manager) AddPlugins(ps ...plugins.Plugin)

func (Manager) Alloc ¶

func (m Manager) Alloc(ctx context.Context, nodename string, deployCount int, opts resourcetypes.Resources) ([]resourcetypes.Resources, []resourcetypes.Resources, error)

Alloc allocates resource for deployCount workloads on nodename, keyed by plugin name in opts.

func (Manager) GetMetricsDescription ¶

func (m Manager) GetMetricsDescription(ctx context.Context) ([]*plugintypes.MetricsDescription, error)

func (Manager) GetMostIdleNode ¶

func (m Manager) GetMostIdleNode(ctx context.Context, nodenames []string) (string, error)

func (Manager) GetNodeMetrics ¶

func (m Manager) GetNodeMetrics(ctx context.Context, node *types.Node) ([]*plugintypes.Metrics, error)

func (Manager) GetNodeResourceInfo ¶

func (m Manager) GetNodeResourceInfo(ctx context.Context, nodename string, workloads []*types.Workload, fix bool) (resourcetypes.Resources, resourcetypes.Resources, []string, error)

func (Manager) GetNodesDeployCapacity ¶

func (m Manager) GetNodesDeployCapacity(ctx context.Context, nodenames []string, opts resourcetypes.Resources) (map[string]*plugintypes.NodeDeployCapacity, int, error)

GetNodesDeployCapacity returns the nodes meeting every plugin's requirements, and their total capacity. the caller must hold the node locks

func (m Manager) Realloc(ctx context.Context, nodename string, nodeResource, opts resourcetypes.Resources) (resourcetypes.Resources, resourcetypes.Resources, resourcetypes.Resources, error)

func (Manager) Remap ¶

func (m Manager) Remap(ctx context.Context, nodename string, workloads []*types.Workload) (map[string]resourcetypes.Resources, error)

Remap returns engine params per workload, format: {"workload-1": {"cpus": ["1-3"]}}. remap never changes resource params
