Types

type NifiClient

type NifiClient interface {
	// System func
	DescribeCluster() (*nigoapi.ClusterEntity, error)
	DisconnectClusterNode(nId int32) (*nigoapi.NodeEntity, error)
	ConnectClusterNode(nId int32) (*nigoapi.NodeEntity, error)
	OffloadClusterNode(nId int32) (*nigoapi.NodeEntity, error)
	RemoveClusterNode(nId int32) error
	GetClusterNode(nId int32) (*nigoapi.NodeEntity, error)
	RemoveClusterNodeFromClusterNodeId(nId string) error

	Build() error
}

NiFiClient is the exported interface for NiFi operations

func New

func New(opts *NifiConfig) NifiClient

func NewFromCluster

func NewFromCluster(k8sclient client.Client, cluster *v1alpha1.NifiCluster) (NifiClient, error)

NewFromCluster is a convenient wrapper around New() and ClusterConfig()

type NifiConfig

type NifiConfig struct {
	NodesURI  map[int32]string
	NifiURI   string
	UseSSL    bool
	TLSConfig *tls.Config

	OperationTimeout int64
	// contains filtered or unexported fields
}

NifiConfig are the options to creating a new ClusterAdmin client

func ClusterConfig

func ClusterConfig(client client.Client, cluster *v1alpha1.NifiCluster) (*NifiConfig, error)

ClusterConfig creates connection options from a NifiCluster CR
