This article mainly shows you "how to modify the port range of kubernetes service nodeport type". The content is simple and clear. I hope it can help you solve your doubts. Let me lead you to study and learn this article "how to modify the port range of kubernetes service nodeport type".
Kubernetes version 1.14.3
Provided port is not in the valid range. The range of valid ports is 30000-32767
Create service in Kubernetes (K8s) and use nodePort to expose external port 6379 Times error
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
Edit the kube-apiserver.yaml file
Vim / etc/kubernetes/manifests/kube-apiserver.yaml
one
Find the-- service-cluster-ip-range line and add the following to the next line of this line
-service-node-port-range=1-65535
The actual case content is as follows
ApiVersion: v1kind: Podmetadata: creationTimestamp: null labels: component: kube-apiserver tier: control-plane name: kube-apiserver namespace: kube-systemspec: 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
Finally restart kubelet
Systemctl daemon-reloadsystemctl restart kubelet
Execute kubectl create-f kube-service.yml again to achieve success.
