如何设置 service-node-port-range 然后能够使用新的端口范围部署服务？

Question

我要求测试服务器应该使用端口范围 20000 - 22767

我kubeadm-config用命令编辑了

kubectl edit cm kubeadm-config -n kube-system

当我查看结果时，我发现更改似乎已被存储：

命令$ kubeadm config view给了我

apiServer:
  extraArgs:
    authorization-mode: Node,RBAC
    service-node-port-range: 20000-22767
  timeoutForControlPlane: 4m0s
apiVersion: kubeadm.k8s.io/v1beta1
certificatesDir: /etc/kubernetes/pki
clusterName: kubernetes
controlPlaneEndpoint: ""
controllerManager: {}
dns:
  type: CoreDNS
etcd:
  local:
    dataDir: /var/lib/etcd
imageRepository: k8s.gcr.io
kind: ClusterConfiguration
kubernetesVersion: v1.13.3
networking:
  dnsDomain: cluster.local
  podSubnet: 10.244.0.0/16
  serviceSubnet: 10.96.0.0/12
scheduler: {}

但是当我稍后尝试在新端口范围内安装某些东西时，我收到错误

helm upgrade --install --kubeconfig /external-storage/workspace/potapi-orchestration/clusters/at/admin.conf potapi-services charts/potapi-services -f charts/potapi-services/values.at.yaml
Error: UPGRADE FAILED: Service "potapi-services" is invalid: spec.ports[0].nodePort: Invalid value: 21011: provided port is not in the valid range. The range of valid ports is 30000-32767

我已经摆弄了这里的建议，但没有运气：https : //github.com/kubernetes/kubeadm/issues/122

可以service-node-port-range从它的默认值更新。

我/etc/kubernetes/manifests/kube-apiserver.yaml用--service-node-port-range=20000-22767.

apiserver 重新启动并更新了端口范围。

我写了一篇关于它的博客文章。
