NewOrcUpdater returns a syncer that updates cluster status from orchestrator.

Types

type InstancesSet

type InstancesSet []orc.Instance

InstancesSet type is a alias for []orc.Instance with extra utils functions

func (InstancesSet) DetermineMaster

func (is InstancesSet) DetermineMaster() *orc.Instance

DetermineMaster returns a orc.Instance that is master or nil if can't find master

func (InstancesSet) GetInstance

func (is InstancesSet) GetInstance(host string) *orc.Instance

GetInstance returns orc.Instance for a given hostname

func (InstancesSet) ToLog

func (is InstancesSet) ToLog() []map[string]string

ToLog returns a list of simplified output for logging

type ReconcileMysqlCluster

type ReconcileMysqlCluster struct {
	client.Client
	// contains filtered or unexported fields
}

ReconcileMysqlCluster reconciles a MysqlCluster object

func (*ReconcileMysqlCluster) Reconcile

func (r *ReconcileMysqlCluster) Reconcile(ctx context.Context, request reconcile.Request) (reconcile.Result, error)

Reconcile reconcile for each mysql cluster state from orchestrator to cluster, this reconcile is triggered in a loop.

Automatically generate RBAC rules to allow the Controller to read and write Deployments
