Functions

func AttachingSlavesToMaster

func AttachingSlavesToMaster(cluster *submarine.Cluster, admin submarine.AdminInterface, slavesByMaster map[string]submarine.Nodes) error

AttachingSlavesToMaster used to attach slaves to there masters

func DispatchMasters

func DispatchMasters(cluster *submarine.Cluster, nodes submarine.Nodes, nbMaster int32, admin submarine.AdminInterface) (submarine.Nodes, submarine.Nodes, submarine.Nodes, error)

DispatchMasters used to select nodes with master roles

func DispatchSlotToNewMasters

func DispatchSlotToNewMasters(cluster *submarine.Cluster, admin submarine.AdminInterface, newMasterNodes, currentMasterNodes, allMasterNodes submarine.Nodes) error

DispatchSlotToNewMasters used to dispatch Slot to the new master nodes

func PlaceMasters

func PlaceMasters(cluster *submarine.Cluster, currentMaster submarine.Nodes, allPossibleMasters submarine.Nodes, nbMaster int32) (submarine.Nodes, bool, error)

PlaceMasters used to select Submarine Node knowing on which VM they are running in order to spread as possible the masters on different VMs. Improvement: Use Kube Node labeling instead of the "NodeName", (availability zone and so)

func PlaceSlaves

func PlaceSlaves(cluster *submarine.Cluster, masters, oldSlaves, newSlaves submarine.Nodes, replicationFactor int32) (map[string]submarine.Nodes, bool)

PlaceSlaves used to select Submarine Node knowing on which VM they are running in order to spread as possible
