Types

type HighLevelClient

type HighLevelClient struct {
	*lapi.Client
	PropertyNamespace string
}

HighLevelClient is a golinstor client with convience functions.

func NewHighLevelClient

func NewHighLevelClient(options ...lapi.Option) (*HighLevelClient, error)

NewHighLevelClient returns a pointer to a golinstor client with convience.

func (*HighLevelClient) GenericAccessibleTopologies

func (c *HighLevelClient) GenericAccessibleTopologies(ctx context.Context, volId string, remoteAccessPolicy volume.RemoteAccessPolicy) ([]*csi.Topology, error)

GenericAccessibleTopologies returns topologies based on linstor storage pools and whether a resource is allowed to be accessed over the network.

func (*HighLevelClient) GetAllTopologyNodes

func (c *HighLevelClient) GetAllTopologyNodes(ctx context.Context, remoteAccessPolicy volume.RemoteAccessPolicy, requisites []*csi.Topology) ([]string, error)

GetAllTopologyNodes returns the list of nodes that satisfy the given topology requirements

func (*HighLevelClient) NodesForTopology

func (c *HighLevelClient) NodesForTopology(ctx context.Context, segments map[string]string) ([]string, error)

NodesForTopology finds all matching nodes for the given topology segment.

In the most common case, this just extracts the node name using the standard topology.LinstorNodeKey. In some cases CSI only gives us an "aggregate" topology, i.e. no node name, just some common property, in which case we query the LINSTOR API for all matching nodes.
