修改kubernetes服务 nodeport 类型的端口范围

kubernetes 版本 1.14.3

provided port is not in the valid range. The range of valid ports is 30000-32767

在 Kubernetes(k8s) 创建 service 使用

nodePort

暴露 外部端口

6379

时报错

The Service “redis” is invalid: spec.ports[0].nodePort: Invalid value: 6379: provided port is not in the valid range. The range of valid ports is 30000-32767

编辑

kube-apiserver.yaml

文件

vim /etc/kubernetes/manifests/kube-apiserver.yaml
           

找到

--service-cluster-ip-range

这一行，在这一行的下一行增加 如下内容

- --service-node-port-range=1-65535
           

实际 案例内容如

apiVersion: v1
kind: Pod
metadata:
  creationTimestamp: null
  labels:
    component: kube-apiserver
    tier: control-plane
  name: kube-apiserver
  namespace: kube-system
spec:
  containers:
  - command:
    - kube-apiserver
    - --advertise-address=192.168.0.254
    - --allow-privileged=true
    - --authorization-mode=Node,RBAC
    - --client-ca-file=/etc/kubernetes/pki/ca.crt
    - --enable-admission-plugins=NodeRestriction
    - --enable-bootstrap-token-auth=true
    - --etcd-cafile=/etc/kubernetes/pki/etcd/ca.crt
    - --etcd-certfile=/etc/kubernetes/pki/apiserver-etcd-client.crt
    - --etcd-keyfile=/etc/kubernetes/pki/apiserver-etcd-client.key
    - --etcd-servers=https://127.0.0.1:2379
    - --insecure-port=0
    - --kubelet-client-certificate=/etc/kubernetes/pki/apiserver-kubelet-client.crt
    - --kubelet-client-key=/etc/kubernetes/pki/apiserver-kubelet-client.key
    - --kubelet-preferred-address-types=InternalIP,ExternalIP,Hostname
    - --proxy-client-cert-file=/etc/kubernetes/pki/front-proxy-client.crt
    - --proxy-client-key-file=/etc/kubernetes/pki/front-proxy-client.key
    - --requestheader-allowed-names=front-proxy-client
    - --requestheader-client-ca-file=/etc/kubernetes/pki/front-proxy-ca.crt
    - --requestheader-extra-headers-prefix=X-Remote-Extra-
    - --requestheader-group-headers=X-Remote-Group
    - --requestheader-username-headers=X-Remote-User
    - --secure-port=6443
    - --service-account-key-file=/etc/kubernetes/pki/sa.pub
    - --service-cluster-ip-range=10.1.0.0/16
    - --service-node-port-range=1-65535
           

最后 重启 kubelet

systemctl daemon-reload
systemctl restart kubelet
           

再执行

kubectl create -f kube-service.yml

即可成功
