OS: Redhat 7.9
Docker and Kubernetes (kubectl,kubelet,kubeadm) installed as per the documentation. Kuberenetes cluster initialized using
sudo kubeadm initAfter this all, on checking 'docker ps', find all the services up.
But all kubectl commands except for 'kubectl config view' fail with error 'Unable to connect to the server: Forbidden'
The issue was with corporate proxy. I had to set the 'no_proxy' as ENV variable and also as part of docker proxy and this issue got resolved.
