What kind of cluster is it? A managed(AKS,EKS or GKE etc) one, where is it deployed? Can you ssh in to master node, if yes, please

cat /etc/kubernetes/admin.conf or cat ~/.kube/config

and copy the file, which is the kubeconfig for your cluster.

Other ways to create the kubeconfig, Run the following command

kubectl config view --minify, it will display all the info except for the client ca certificate and client key. The location of those keys depends on how the cluster is setup. kubectl config view --raw will show all the configuration (including certificates).

First, locate your kubeconfig file. Generally, it is present at following location: /etc/kubernetes/admin.conf

And then export it by running following command:

export KUBECONFIG=/etc/kubernetes/admin.conf

It is also a good idea to add it in ~/.bashrc file so that you don't have to export it again when the kubeconfig changes.

I have several clusters running on GKE and ssh'ing into the master node didn't work for me, but I was able to run cat ~/.kube/config locally and it gave me everything I needed including the certificate information I needed for my 3rd party application.

Make sure you connect locally so your kubectl is configured correctly,

gcloud container clusters get-credentials

Hopefully, that helps.

You can use gcloud to generate a kubeconfig entry, given that you have at least clusterViewer IAM role:

gcloud container clusters get-credentials cluster-name
