Types

type NodeProvider

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

NodeProvider accepts a callback from virtual-kubelet's node controller, and exposes it to our upstream resources controller, for node status updates. If we updated node status directly, without informing virtual-kubelet, virtual-kubelet would override our changes every minute (with node leases enabled; more often otherwise); which would trigger a reconcile on our end, and another override on vk's end, etc. (controllers disagreeing). When virtual-kubelet is notified of what we think the node status should be, it keeps it in memory, and call kube-apiserver on our behalf.

func (*NodeProvider) NotifyNodeStatus

func (p *NodeProvider) NotifyNodeStatus(ctx context.Context, cb func(*corev1.Node))

func (*NodeProvider) Ping

func (p *NodeProvider) Ping(ctx context.Context) error

func (*NodeProvider) UpdateNodeStatus

func (p *NodeProvider) UpdateNodeStatus(node *corev1.Node)

type Opts

type Opts struct {
	NodeName        string
	EnableNodeLease bool
}
