Types

type DatabaseAccountReconciler

type DatabaseAccountReconciler struct {
	client.Client
	Scheme        *runtime.Scheme
	Recorder      Recorder
	AccountServer accountsvr.Server

func (*DatabaseAccountReconciler) Reconcile

func (r *DatabaseAccountReconciler) Reconcile(ctx context.Context, req ctrl.Request) (ctrl.Result, error)

Reconcile is part of the main kubernetes reconciliation loop which aims to move the current state of the cluster closer to the desired state. TODO(user): Modify the Reconcile function to compare the state specified by the DatabaseAccount object against the actual cluster state, and then perform operations to make the cluster state reflect the state specified by the user.

For more details, check Reconcile and its Result here: - https://pkg.go.dev/sigs.k8s.io/controller-runtime@v0.14.4/pkg/reconcile
