This is my homelab. Ansible setup for my homelab. Still a work in progress.

Download this repo to the control machine. Then run the following commands:

git clone https://github.com/davidccunliffe/homelab.git

Add the kube configs to the user account

rm -rf $HOME/.kube
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config

systemctl stop kubelet
systemctl stop containerd
iptables --flush
iptables -tnat --flush
