The problem i'm running into is very similar to the other existing post, except they all have the same solution therefore im creating a new thread.
The Problem: The Master node is still in "NotReady" status after installing Flannel.
Expected result: Master Node becomes "Ready" after installing Flannel.
Background: I am following this guide when installing Flannel
My concern is that I am using Kubelet v1.17.2 by default that just came out like last month (Can anyone confirm if v1.17.2 works with Flannel?"
Here is the output after running the command on master node: kubectl describe node machias
