Utils contains options to define the behavior of the controllers and functions used by the controllers. Signed-off-by: Elis Lulja <[email protected]>
The namespace controller is now defined with a series of predicates that will dicatate whether the event should be passed to the namespace controller or be ignored. Signed-off-by: Elis Lulja <[email protected]>
The namespace controller reconcile function is updated to reflect changes in the predicates. As a result, it becomes much slimmer and simpler. Signed-off-by: Elis Lulja <[email protected]>
This commit adds predicates to the service controller in the same fashion as what was done for the namespace controller. Unit tests included. Signed-off-by: Elis Lulja <[email protected]>
The service controller's reconcile function has been updated to reflect the addition of predicates. As a consequence, the reconcile function is shorter, readable and intuitive, as it now is invoked *only* when there is actually a need for reconciliation, i.e. no additional parsing is needed. Signed-off-by: Elis Lulja <[email protected]>
This commit updates main.go to reflect the changes in the controller. More precisely, main starts controller utils and sets it up in the namespace and service controllers. Signed-off-by: Elis Lulja <[email protected]>
This commit adds the ability to enable the pods counting feature and choose the annotation key that will be registered in the service's metadata. Signed-off-by: Elis Lulja <[email protected]>
baseReconciler is meant to replace controller utils as it includes common functions and structures and serves as the basis for all other controllers. Signed-off-by: Elis Lulja <[email protected]>
The existing reconcilers, Namespace and Service, now inherit methods and variables from BaseReconcilers. Main has been updated to reflect such change. Signed-off-by: Elis Lulja <[email protected]>
This commit adds the EndpointSliceReconciler and makes it inherit the BaseReconciler. Signed-off-by: Elis Lulja <[email protected]>
This commit updates the roles with proper permissions to perform operations on endpointslices on Kubernetes. Signed-off-by: Elis Lulja <[email protected]>
In this commit the Reconcile function of the endpointslice controller is implemented and calculates the total number of endpoints for a service. Signed-off-by: Elis Lulja <[email protected]>
This commit prevents the endpointsliceReconciler from being started (actually, inited) if the user didn't enable the feature on settings. Also, it adds the annotation key in the base reconciler. Signed-off-by: Elis Lulja <[email protected]>
This commit updates all reconciler' Reconcile function to get and update the number of pods backing the service on the service registry. Signed-off-by: Elis Lulja <[email protected]>
A window is implemented, where values are inserted and kept in memory for a short time before updating service directory values. Signed-off-by: Elis Lulja <[email protected]>

This PR introduces the feature to watch for the number of pods backing a service by counting the number of
Endpointscontained inside a service'sEndpointSlices.Whenever a change is detected, the operator registers the number of pods as a value in the service's metadata to the service registry. The key is configurable.
This depends from #37 and will be rebased once that is merged.
NOTE: This is a work in progress.
