Minikube has the specific node ip address (192.168.99.100) for single cluster, if I using kubeadm to create many nodes cluster, what should I do to find this ip address?

This should be fairly straightforward: kubectl get nodes -o wide

IP Address for Active Cluster Node, Now, it's not hard to find out which is the actual IP Address of the node and which one is for the (Cluster Name Object), using the Route Table or� Try this, put your Cluster VIP in the below code and it should list you the cluster nodes. $clustername = (Get-cluster -Name 1.1.1.1).Name (Get-ClusterNode -Cluster $clustername).Name And if you have bunch of VIPs and want to get the node details, you can try below code:

To get informations about Kubernetes objects you should use kubectl get <resource> or kubectl describe <resource>.

In docs

Display one or many resources

Prints a table of the most important information about the specified resources. You can filter the list using a label selector and the --selector flag. If the desired resource type is namespaced you will only see results in your current namespace unless you pass --all-namespaces.

If you will check manual for kubectl get you will get information about -o flag.

-o, --output='': Output format. One of: json|yaml|wide|name|custom-columns=...|custom-columns-file=...|go-template=...|go-template-file=...|jsonpath=...|jsonpath-file=... See custom columns [http://kubernetes.io/docs/user-guide/kubectl-overview/#custom-columns], golang template [http://golang.org/pkg/text/template/#pkg-overview] and jsonpath template [http://kubernetes.io/docs/user-guide/jsonpath].

Thats mean you can get output in YAMLs or JSON format. Detailed information can be found in this doc.

As @Bernard Halas mentioned, you can just use kubectl get nodes -o wide.

Another option is use describe with grep. -A will print number lines of trailing context. Its helpful if you need to get list about information per node.

$ kubectl describe node | grep Addresses: -A 4
Addresses:
  InternalIP:   10.164.0.63
  ExternalIP:   35.204.67.223
  InternalDNS:  gke-test-default-pool-d11b1330-g44z.c.composite-rune-239911.internal
  Hostname:     gke-test-default-pool-d11b1330-g44z.c.composite-rune-239911.internal

Addresses:
  InternalIP:   10.164.0.61
  ExternalIP:   35.204.63.113
  InternalDNS:  gke-test-default-pool-d11b1330-gtpj.c.composite-rune-239911.internal
  Hostname:     gke-test-default-pool-d11b1330-gtpj.c.composite-rune-239911.internal

Addresses:
  InternalIP:   10.164.0.62
  ExternalIP:   35.204.202.107
  InternalDNS:  gke-test-default-pool-d11b1330-r4dw.c.composite-rune-239911.internal
  Hostname:     gke-test-default-pool-d11b1330-r4dw.c.composite-rune-239911.internal

You can also use YAML or JSON format. Output will be similar to previous one.

$ kubectl get nodes -o yaml | grep addresses: -A 8
    addresses:
    - address: 10.164.0.63
      type: InternalIP
    - address: 35.204.67.223
      type: ExternalIP
    - address: gke-test-default-pool-d11b1330-g44z.c.composite-rune-239911.internal
      type: InternalDNS
    - address: gke-test-default-pool-d11b1330-g44z.c.composite-rune-239911.internal
      type: Hostname
...

In addition if you will need some specific output (only information you need and ar not print as default) you can use custom columns. It's based on YAML format.

$ kubectl get pods -o custom-columns=Name:.metadata.name,NS:.metadata.namespace,HostIP:.status.hostIP,PodIP:status.podIP,REQ_CPU:.spec.containers[].resources.requests.cpu
Name                          NS        HostIP        PodIP       REQ_CPU

Get-ClusterNode, The Get-ClusterNode cmdlet gets information about one or more nodes, Cluster Disk 1 Online Cluster Group Physical Disk Cluster IP Address Online Cluster� Double-click the IP Address resource to open its properties. On the Parameters tab in the IP Address resource properties, make sure that the Network to Use box contains the new network as the network to use. Fail all groups over to the functional node A. Change the IP addresses for the network adapters in node B. Reboot the computer. When both nodes agree on the subnets, the old networks disappear and the new networks are created.

How to find cluster node ip address, This should be fairly straightforward: kubectl get nodes -o wide. ssh into your cluster's head node and run $curl ifconfig.me command to get the IP address of head nodes. You can get fully qualified domain names (FQDN) of all nodes on the cluster using below bash command (Replace $CLUSTERNAME with your cluster name).

Here's a command that should show the internal IP addresses of each node in the cluser:

ubuntu@astrocyte:~$ kubectl get nodes -o yaml | grep -- "- address:"
    - address: 192.168.1.6
    - address: astrocyte
    - address: 192.168.1.20
    - address: axon2.local
    - address: 192.168.1.7
    - address: axon3.local

It also shows hostnames, if you have them configured

Better way to get Microsoft Failover Cluster IP address resource , This will be a little bit cleaner. It'll return just the IP address. get-clusterresource - name "cluster ip address" | get-clusterparameter -name Address | select� Each node should have its own IP address on the public network for administrative purposes so that the nodes can be addressed even if they do not have any applications running at a particular time (2 more) Each application will need its own IP address, so that it can failover separately between the nodes (2 more) That sounds like eight to me.

IP Addresses in a Microsoft Failover Cluster Configuration, You have two IP addresses for each cluster node, one IP address for the cluster, one for the SAP cluster group, and one for the database cluster group. Some of� Issue the following command as the root user on a single node: runact -c IBM.PeerDomain SyncConfig TargetNodes=' {"<node_01>","<node_02>"}'. Replace <node_01> and <node_02> with your own hostnames. Wait a few minutes before then rechecking step #8 to verify that the new IP addresses have been picked up.

To find the cluster IP address of a Kubernetes pod, use the kubectl get pod command on your local machine, with the option -o wide. This option will list more information, including the node the pod resides on, and the pod’s cluster IP. kubectl get pod -o wide

The isi networks command is the most popular and widely used command to get network information about an Isilon cluster, but there is another way to get detailed information about networking info when you are troubleshooting OneFS. Use the folloing commands:
