Functions

func Add

func Add(mgr manager.Manager) error

Add creates a new DNSZone Controller and adds it to the Manager with default RBAC. The Manager will set fields on the Controller and Start it when the Manager is Started.

func DeleteAWSRecordSets

func DeleteAWSRecordSets(awsClient awsclient.Client, dnsZone *hivev1.DNSZone, logger log.FieldLogger) error

DeleteAWSRecordSets will clean up a DNS zone down to the minimum required record entries

func DeleteAzureRecordSets

func DeleteAzureRecordSets(azureClient azureclient.Client, dnsZone *hivev1.DNSZone, logger log.FieldLogger) error

DeleteAzureRecordSets will remove all non-essential records from the DNSZone provided.

func DeleteGCPRecordSets

func DeleteGCPRecordSets(gcpClient gcpclient.Client, dnsZone *hivev1.DNSZone, logger log.FieldLogger) error

DeleteGCPRecordSets will delete all non-essential DNS records in the DNSZone provided

func IsClusterDeploymentDNSErrorUpdateEvent

func IsClusterDeploymentDNSErrorUpdateEvent(evt event.UpdateEvent) bool

IsClusterDeploymentDNSErrorUpdateEvent returns true when the update event in ClusterDeployment is from DNS error state.

func IsErrorUpdateEvent

func IsErrorUpdateEvent(evt event.UpdateEvent) bool

IsErrorUpdateEvent returns true when the update event for DNSZone is from error state.

Types

type AWSActuator

type AWSActuator struct {
	// contains filtered or unexported fields
}

AWSActuator manages getting the desired state, getting the current state and reconciling the two.

func NewAWSActuator

func NewAWSActuator(
	logger log.FieldLogger,
	kubeClient client.Client,
	credentials awsclient.CredentialsSource,
	dnsZone *hivev1.DNSZone,
	awsClientBuilder awsClientBuilderType,
) (*AWSActuator, error)

NewAWSActuator creates a new AWSActuator object. A new AWSActuator is expected to be created for each controller sync.

func (*AWSActuator) Create

func (a *AWSActuator) Create() error

Create makes an AWS Route53 hosted zone given the DNSZone object.

func (*AWSActuator) Delete

func (a *AWSActuator) Delete() error

Delete removes an AWS Route53 hosted zone, typically because the DNSZone object is in a deleting state.

func (*AWSActuator) Exists

func (a *AWSActuator) Exists() (bool, error)

Exists determines if the route53 hosted zone corresponding to the DNSZone exists

func (*AWSActuator) GetNameServers

func (a *AWSActuator) GetNameServers() ([]string, error)

GetNameServers returns the nameservers listed in the route53 hosted zone NS record.

func (*AWSActuator) Refresh

func (a *AWSActuator) Refresh() error

Refresh gets the AWS object for the zone. If a zone cannot be found or no longer exists, actuator.zoneID remains unset.

func (*AWSActuator) SetConditionsForError

func (a *AWSActuator) SetConditionsForError(err error) bool

SetConditionsForError sets conditions on the dnszone given a specific error. Returns true if conditions changed.

func (*AWSActuator) UpdateMetadata

func (a *AWSActuator) UpdateMetadata() error

UpdateMetadata ensures that the Route53 hosted zone metadata is current with the DNSZone

type Actuator

type Actuator interface {
	// Create tells the actuator to make a zone in the dns provider.
	// The platform-specific DNSZone status fields will be populated (eg the zone name).
	Create() error

	// Delete tells the actuator to remove the zone from the dns provider.
	Delete() error

	// Exists queries if the zone is in the dns provider.
	Exists() (bool, error)

	// UpdateMetadata tells the actuator to update the zone's metadata in the dns provider.
	UpdateMetadata() error

	// GetNameServers returns a list of nameservers that service the zone in the dns provider.
	GetNameServers() ([]string, error)

	// Refresh signals to the actuator that it should get the latest version of the zone from the dns provider.
	// Refresh MUST be called before any other function is called by the actuator.
	// Refresh will update the DNSZone object's platform-specific status fields.
	Refresh() error

	// SetConditionsForError sets conditions on the dnszone given a specific error
	SetConditionsForError(err error) bool
}

Actuator interface is the interface that is used to add dns provider support to the dnszone controller.

type AzureActuator

	// contains filtered or unexported fields
}

AzureActuator attempts to make the current state reflect the given desired state.
