ansible-playbook with ansible.yaml fails when python-netaddr is missing

[digitalgopnik]

Hello @fnkr!

Thanks for this helpful repository :) I came across this repository, because i was searching for a well documented and working example, which provides a kubernetes cluster with terraform (and ansible) on hetzner-cloud-servers.

Did you face the following issue during ansible-playbook ansible.yaml?

TASK [k8s : Template kubelet service overrides] *************************************************************************************************************
fatal: [testkube-control-001]: FAILED! => {"msg": "The ipaddr filter requires python's netaddr be installed on the ansible controller"}

Anyway, if not, i think you should add a hint to the README, so that other users will know, they have to install python3-netaddr, python-netaddr or simply pip3 install netaddr(for virtualenv) as described in here: ansible/workshops#115

Please install dependencies from requirements.txt first, e.g.

python3 -m venv venv
venv/bin/pip install -r requirements.txt
. venv/bin/activate

Instructions are now in the README too.
