Types

type ConfigMapClient

type ConfigMapClient interface {
	Get(ctx context.Context) (*v1.ConfigMap, error)
	Update(ctx context.Context, cfg *v1.ConfigMap) error
}

ConfigMapClient is an abstraction over different ways to interact with a ConfigMap.

type DNSEntry

type DNSEntry struct {
	PodName string
	Network string
	Scope   string
}

type DNSManager

type DNSManager interface {
	GetConfigMap(ctx context.Context) (*v1.ConfigMap, error)
	AddDNSEntryToConfigMap(ctx context.Context, updatedData map[string]string) error
	RemoveDNSRecords(ctx context.Context, removals map[string][]string) error
	ListDNSRecords(ctx context.Context) (map[string][]string, error)
	AddDNSEntry(ctx context.Context, dnsName, ipAddress string) error
	RemoveDNSEntry(ctx context.Context, key string) error
	AddServerToConfigMap(ctx context.Context, domainName, serverDomain, serverPort string) error
}

DNSManager defines the interface for managing CoreDNS ConfigMaps.

func NewDNSManager

func NewDNSManager(namespace, configMap string, k8sConfig *rest.Config, crClient client.Client) (DNSManager, error)

NewDNSManager is the factory function that creates a DNSManager. If crClient is provided (non-nil), it uses the controller-runtime client; otherwise, it falls back to using the standard Kubernetes clientset.
