Types

type AddOptions

type AddOptions struct {
	// Controller are the controller.Options.
	Controller controller.Options
	// IgnoreOperationAnnotation specifies whether to ignore the operation annotation or not.
	IgnoreOperationAnnotation bool
	// ExtensionClass defines the extension class this extension is responsible for.
	ExtensionClass extensionsv1alpha1.ExtensionClass
}

AddOptions are Options to apply when adding the Azure bastion controller to the manager.

type Options

type Options struct {
	BastionInstanceName string
	BastionPublicIPName string
	PrivateIPAddressV4  string
	PrivateIPAddressV6  string
	ResourceGroupName   string
	SecurityGroupName   string
	Location            string
	NicName             string
	NicID               string
	DiskName            string
	SecretReference     corev1.SecretReference
	WorkersCIDR         []string
	CIDRs               []string
	Tags                map[string]*string
}

Options contains provider-related information required for setting up a bastion instance. This struct combines precomputed values like the bastion instance name with the IDs of pre-existing cloud provider resources, like the nic name etc.

func DetermineOptions

func DetermineOptions(bastion *extensionsv1alpha1.Bastion, cluster *controller.Cluster, resourceGroup string) (*Options, error)

DetermineOptions determines the information that are required to reconcile a Bastion on Azure. This function does not create any IaaS resources.
