Most of the setup of the OS was already done for us by the bootstrap file, before we had to set up manually on Ubuntu following:
- Removing snap
- Update OS
- Edit to cmdline.txt
- Remove ipv6
- Disable green led
Pretty much everything is done for us by the bootstrap file. So much time saved ! And super easy and quick way to bring up new node.
We need iptables, k3s / Kubernetes needs it. As
root run following to install them to every node:
ansible cube -m apt -a "name=iptables state=present" --become
Then reboot the worker nodes for good measure.
ansible workers -b -m shell -a "reboot"
That should really be all, Lets move on to the next step.
