Functions

func InstallFlags

func InstallFlags(flags *pflag.FlagSet, c *Opts)

func NewCommand

func NewCommand(ctx context.Context, name string, s *provider.Store, c *Opts) *cobra.Command

NewCommand creates a new top-level command. This command is used to start the virtual-kubelet daemon.

func NodeFromProvider

func NodeFromProvider(ctx context.Context, name string, p provider.Provider, version string, refs []metav1.OwnerReference,
	nodeExtraAnnotations, nodeExtraLabels map[string]string) (*corev1.Node, error)

NodeFromProvider builds a kubernetes node object from a provider This is a temporary solution until node stuff actually split off from the provider interface itself.

func SetDefaultOpts

func SetDefaultOpts(c *Opts) error

SetDefaultOpts sets default options for unset values on the passed in option struct. Fields tht are already set will not be modified.

Types

type Opts

type Opts struct {
	// Domain suffix to append to search domains for the pods created by virtual-kubelet
	KubeClusterDomain string

	// Sets the port to listen for requests from the Kubernetes API server
	ListenPort int32

	// Node name to use when creating a node in Kubernetes
	NodeName string

	Provider string

	HomeKubeconfig string

	MetricsAddr string

	// Number of workers to use to handle pod notifications
	PodSyncWorkers           int
	InformerResyncPeriod     time.Duration
	LiqoInformerResyncPeriod time.Duration

	// Use node leases when supported by Kubernetes (instead of node status updates)
	EnableNodeLease bool

	TraceExporters  []string
	TraceSampleRate string

	// Startup Timeout is how long to wait for the kubelet to start
	StartupTimeout time.Duration

	ForeignClusterID string
	HomeClusterID    string
	KubeletNamespace string

	LiqoIpamServer string

	Version   string
	Profiling bool

	NodeExtraAnnotations argsutils.StringMap
	NodeExtraLabels      argsutils.StringMap
}

Opts stores all the options for configuring the root virtual-kubelet command. It is used for setting flag values.

You can set the default options by creating a new `Opts` struct and passing it into `SetDefaultOpts`.
