Functions ¶
Types ¶
type MachineConfigReconciler ¶
type MachineConfigReconciler struct {
Log logr.Logger
Scheme *runtime.Scheme
EventRecorder record.EventRecorder
// contains filtered or unexported fields
}
MachineConfigReconciler reconciles a NodeObservabilityMachineConfig object
func New ¶
func New(mgr ctrl.Manager) *MachineConfigReconciler
New returns a new MachineConfigReconciler instance.
func (*MachineConfigReconciler) Reconcile ¶
func (r *MachineConfigReconciler) 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.
For more details, check Reconcile and its Result here: - https://pkg.go.dev/sigs.k8s.io/controller-runtime@v0.11.0/pkg/reconcile
Reconcile here is for NodeObservabilityMachineConfig controller, which aims to keep the state as required by the NodeObservability operator. If for any service(ex: CRI-O) requires debugging to be enabled/disabled through the MachineConfigs, controller creates the required MachineConfigs, MachineConfigPool and labels the nodes where the changes are to be applied.
func (*MachineConfigReconciler) SetupWithManager ¶
func (r *MachineConfigReconciler) SetupWithManager(mgr ctrl.Manager) error
SetupWithManager sets up the controller with the Manager.
type ResourcePatchValue ¶
type ResourcePatchValue struct {
Op string `json:"op"`
Path string `json:"path"`
Value interface{} `json:"value,omitempty"`
}
ResourcePatchValue is for creating the patch request for updating a resource
