A Reconciler implements a function which takes a reconcile Request containing the name and namespace of the object to reconcile, reconciles the object, and returns a Response or an error indicating whether to requeue for a second round of processing. +As you can see in the diagram above, a Reconciler is part of a Controller. A Controller has a function to watch changes of the target resources, put change events into the queue, and call **Reconcile** function with an queue item, and requeue the item if necessary. + ## Types diff --git a/contents/kubernetes-operator/controller-runtime/reconciler/diagram.drawio.svg b/contents/kubernetes-operator/controller-runtime/reconciler/diagram.drawio.svg new file mode 100644 index 00000000..266d737e --- /dev/null +++ b/contents/kubernetes-operator/controller-runtime/reconciler/diagram.drawio.svg @@ -0,0 +1,198 @@ + + + + + + + +
