Static Routing issue (Kali VM) and kube-apiserver process using 100%CPU

[thesecmaestro]

Configuration:
Ansible Control Machine (Kali 2018.4 VM), using VMWare Workstation (natt'ed network)
Pull of ansible-rpi-k8s-project of 11/7/18.

Since both issues described here (static routing issue) and CPU spike kube-apiserver might be related keeping issues together in one report for now.

Problem 1: Static Routing issue - SSH Kali host
Cannot ssh from Ansible Control Machine (192.168.80.135) to rpi-k8s-1 (192.168.1.100, statically assigned). ssh to WIFI (DHCP) address (15.15.15.147) works fine

Expected results:
ssh from 192.168.80.135 to 192.168.1.100 to work (Similar as to 15.15.15.147)

Problem 2: kube-apiserver process consumes CPU and freezes rpi-k8s-1 within minutes
After successful execution of ansible-playbook -i inventory playbooks/deploy.yml, kube-apiserver
(by resolving issue 1 & 2 listed below) process runs out of memory and freezes rpi-k8s-1 within minutes
Workaround: manually kill kube-apiserver process each few minutes

Expected results:
Expect rpi-k8s-1 to continue to function (cap memory usage of of kube-apiserver process)

Resolved Issue 1:
ssh to 15.15.15.147 (WIFI rpi-k8s-1) fails.
SOLVED: Updated ansible.cfg: ssh_args = -o IPQos=throughput

Resolved Issue 2:
ansible-playbook -i inventory playbooks/deploy.yml fails to contact slave nodes

Snippet error in output

After resolving issue 1 & 2 : ansible-playbook -i inventory playbooks/deploy.yml completes successfully

Continued/existing problems:

Problem 1: Cannot ssh to rpi-k8s-1 (192.168.1.100, statically assigned)
Ssh to rpi-k8s-1 (15.15.15.147, wifi, dhcp) works fine

Problem 2: Kube-apiserver consumes 100%cpu every few minutes and freezes rpi-k8s-1
