示例1: attemptToUpdateMasterRoleLabelsAndTaints
func attemptToUpdateMasterRoleLabelsAndTaints(client *clientset.Clientset, schedulable bool) error {
n, err := findMyself(client)
if err != nil {
return err
}
n.ObjectMeta.Labels[metav1.NodeLabelKubeadmAlphaRole] = metav1.NodeLabelRoleMaster
if !schedulable {
taintsAnnotation, _ := json.Marshal([]v1.Taint{{Key: "dedicated", Value: "master", Effect: "NoSchedule"}})

}
if _, err := client.Nodes().Update(n); err != nil {

fmt.Println("[apiclient] Temporarily unable to update master node metadata due to conflict (will retry)")
time.Sleep(apiCallRetryInterval)
attemptToUpdateMasterRoleLabelsAndTaints(client, schedulable)
} else {
return err
}
}
return nil
}示例2: checkForNodeNameDuplicates
// checkForNodeNameDuplicates checks whether there are other nodes in the cluster with identical node names.
func checkForNodeNameDuplicates(clientSet *clientset.Clientset) error {
hostName, err := os.Hostname()
if err != nil {
return fmt.Errorf("Failed to get node hostname [%v]", err)
}
_, err = clientSet.Nodes().Get(hostName, metav1.GetOptions{})
if err != nil && !apierrs.IsNotFound(err) {
return err
}
return nil
}示例3: findMyself
// It's safe to do this for alpha, as we don't have HA and there is no way we can get
// more then one node here (TODO(phase1+) use os.Hostname)
func findMyself(client *clientset.Clientset) (*v1.Node, error) {
nodeList, err := client.Nodes().List(v1.ListOptions{})
if err != nil {
return nil, fmt.Errorf("unable to list nodes [%v]", err)
}
if len(nodeList.Items) < 1 {
return nil, fmt.Errorf("no nodes found")
}
node := &nodeList.Items[0]
return node, nil
}示例4: getNode
// getNode gets node object from the apiserver.
func getNode(c *clientset.Clientset) (*v1.Node, error) {
nodes, err := c.Nodes().List(v1.ListOptions{})
Expect(err).NotTo(HaveOccurred(), "should be able to list nodes.")
if nodes == nil {
return nil, fmt.Errorf("the node list is nil.")
}

if len(nodes.Items) == 0 {
return nil, fmt.Errorf("empty node list: %+v", nodes)
}
return &nodes.Items[0], nil
