If you need to access your Kubernetes environment remotely, follow these steps:
- Create a ~/.kube directory on your client machine and then SCP (short for Secure Copy) the ~/.kube/config file from the Kubernetes master to your ~/.kube directory.
- Run this on the Kubernetes master node:
$ kubectl -n kube-system describe secret $(kubectl -n kube-system get secret | grep admin | awk '{print $1}')
Here's the output:
