kubectl proxy unauthorized when accessing from another machine

proxy kubernetes kubectl

The --accept-hosts access control is for checking of the hostname, so it won't start with a / (slash). You need to do:

kubectl proxy --address 0.0.0.0 --accept-hosts '.*'

(Make sure you shell escape the .* as it may match files in the current directory!)

proxy kubernetes kubectl

In case someone stumbles upon this question and wants to restrict the access to the Host of the Guest VM.

I'm using VirtualBox, and I was able to allow access only from the Host machine by using localhost and using SSH tunnel to the Guest VM

In Guest VM

$ kubectl proxy --address='0.0.0.0' --port=8002 --accept-hosts='localhost'

In Host machine I've added a hostname reference to static IP of the master plane kubemaster

$ echo "192.168.224.23 kubemaster" >> /etc/hosts$ ssh -N -L 8001:localhost:8002 kube@kubemaster
