### Deploying k3s on a rpi4o
Enable legacy IP tables. [Rancher Docs](https://rancher.com/docs/k3s/latest/en/advanced/#enabling-legacy-iptables-on-raspberry-pi-os
)
```bash
sudo iptables -F
sudo update-alternatives --set iptables /usr/sbin/iptables-legacy
sudo update-alternatives --set ip6tables /usr/sbin/ip6tables-legacy
sudo reboot
```
```bash
#Change the hostname of the node to something unique
vi /etc/hostname
#Kubectl
curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/arm64/kubectl"
install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl
sudo mkdir -p /etc/rancher/k3s && \
cat <> ~/.bash_profile
#Retrieve the node-token (You'll need this to add more nodes to your cluster)
cat /var/lib/rancher/k3s/server/node-token
```
Add more nodes to the cluster with:
```bash
#Enable legacy iptables with the commands above before running this command
curl -sfL https://get.k3s.io | K3S_URL=https://:6443 K3S_TOKEN= sh -
```
### Nothing works. HELP
I understand that this repo is not really documented (sorry). You can get a lot of valuable information and assistance online. k3s + raspberry pi is a very popular combo with multiple communities.
The website [rpi4cluster.com](https://rpi4cluster.com/) is an awesome source of information to get a better understanding of the whole setup.
Feel free to open an issue if you get stuck though, i'll do my best to help.
### TODO
- Add action to update manifest versions.
Example:
```bash
latest=$(curl -s https://api.github.com/repos/cert-manager/cert-manager/releases/latest | jq -r .tarball_url | cut -d/ -f8 | sed "s/v//g")
echo $latest
```
