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.
