问题描述
我要求测试服务器使用端口范围20000-22767
I have a requirement that a test server should use the port range 20000 - 22767
我用命令编辑了kubeadm-config
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:
When I look at the result I see that the change seems to have been stored:
$ kubeadm config view命令给我
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: {}
但是当我以后尝试在新的端口范围内安装某些东西时，我会收到错误消息
But when I later try to install something within hte new port range I get the error
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
我在这里摆弄了建议，但没有运气: https://github.com /kubernetes/kubeadm/issues/122
I have fiddled with the suggestions here but with no luck: https://github.com/kubernetes/kubeadm/issues/122
推荐答案
可以从默认值更新service-node-port-range.
我用--service-node-port-range=20000-22767更新了文件/etc/kubernetes/manifests/kube-apiserver.yaml.
apiserver已重新启动，并且端口范围已更新.
The apiserver was restarted and the port range was updated.
我写了博客帖子关于它.
