Types

type ConfigEntryController 

type ConfigEntryController struct {
	// ConsulClientConfig is the config for the Consul API client.
	ConsulClientConfig *consul.Config

	// ConsulServerConnMgr is the watcher for the Consul server addresses.
	ConsulServerConnMgr consul.ServerConnectionManager

	// DatacenterName indicates the Consul Datacenter name the controller is
	// operating in. Adds this value as metadata on managed resources.
	DatacenterName string

	// EnableConsulNamespaces indicates that a user is running Consul Enterprise
	// with version 1.7+ which supports namespaces.
	EnableConsulNamespaces bool

	// ConsulDestinationNamespace is the name of the Consul namespace to create
	// all config entries in. If EnableNSMirroring is true this is ignored.
	ConsulDestinationNamespace string

	// EnableNSMirroring causes Consul namespaces to be created to match the
	// k8s namespace of any config entry custom resource. Config entries will
	// be created in the matching Consul namespace.
	EnableNSMirroring bool

	// NSMirroringPrefix is an optional prefix that can be added to the Consul
	// namespaces created while mirroring. For example, if it is set to "k8s-",
	// then the k8s `default` namespace will be mirrored in Consul's
	// `k8s-default` namespace.
	NSMirroringPrefix string

	// CrossNSACLPolicy is the name of the ACL policy to attach to
	// any created Consul namespaces to allow cross namespace service discovery.
	// Only necessary if ACLs are enabled.
	CrossNSACLPolicy string
}

ConfigEntryController is a generic controller that is used to reconcile all config entry types, e.g. ServiceDefaults, ServiceResolver, etc, since they share the same reconcile behaviour.

func (*ConfigEntryController) ReconcileEntry 

func (r *ConfigEntryController) ReconcileEntry(ctx context.Context, crdCtrl Controller, req ctrl.Request, configEntry common.ConfigEntryResource) (ctrl.Result, error)

ReconcileEntry reconciles an update to a resource. CRD-specific controller's call this function because it handles reconciliation of config entries generically. CRD-specific controller should pass themselves in as updater since we need to call back into their own update methods to ensure they update their internal state.

type ControlPlaneRequestLimitController 

type ControlPlaneRequestLimitController struct {
	client.Client
	FinalizerPatcher
	Log                   logr.Logger
	Scheme                *runtime.Scheme
	ConfigEntryController *ConfigEntryController
}

func (*ControlPlaneRequestLimitController) UpdateStatus 

func (r *ControlPlaneRequestLimitController) UpdateStatus(ctx context.Context, obj client.Object, opts ...client.SubResourceUpdateOption) error

type Controller 

type Controller interface {
	// AddFinalizersPatch creates a patch with the original finalizers with new ones appended to the end.
	AddFinalizersPatch(obj client.Object, finalizers ...string) *FinalizerPatch
	// RemoveFinalizersPatch creates a patch to remove a set of finalizers, while preserving the order.
	RemoveFinalizersPatch(obj client.Object, finalizers ...string) *FinalizerPatch
	// Patch patches the object. This should only ever be used for updating the metadata of an object, and not object
	// spec or status. Updating the spec could have unintended consequences such as defaulting zero values.
	Patch(ctx context.Context, obj client.Object, patch client.Patch, opts ...client.PatchOption) error
	// UpdateStatus updates the state of just the object's status.
	UpdateStatus(context.Context, client.Object, ...client.SubResourceUpdateOption) error
	// Get retrieves an obj for the given object key from the Kubernetes Cluster.
	// obj must be a struct pointer so that obj can be updated with the response
	// returned by the Server.
	Get(ctx context.Context, key client.ObjectKey, obj client.Object, opts ...client.GetOption) error
	// Logger returns a logger with values added for the specific controller
	// and request name.
	Logger(types.NamespacedName) logr.Logger
}

Controller is implemented by CRD-specific configentries. It is used by ConfigEntryController to abstract CRD-specific configentries.

type ExportedServicesController

type FinalizerPatch 

type FinalizerPatch struct {
	NewFinalizers []string
}

func (*FinalizerPatch) Data 

func (fp *FinalizerPatch) Data(obj client.Object) ([]byte, error)

Data implements client.Patch.

func (*FinalizerPatch) Type 

func (fp *FinalizerPatch) Type() types.PatchType

Type implements client.Patch. Since this patch is used for a custom CRD, Kubernetes does not allow the more advanced StrategicMergePatch. Therefore, this patcher will replace the entire list of finalizers with the new list, rather than adding/removing individual entries.

This can result in a small race condition where we could overwrite recently modified finalizers (either modified by a user or another controller process). Before the addition of this finalizer patcher implementation, this race condition still existed, but applied to the entirety of the CRD because we used to update the entire CRD rather than just the finalizer, so this reduces the surface area of the race condition. Generally we should not expect users or other configentries to be touching the finalizers of consul-k8s managed CRDs.
