# k3p4
K3P4 - 4 node Raspberry Pi Cluster using k3s
Goal of this project:
I want to learn k8s deployments and hosting various apps on it, and I want to mess around with raspberry pis.
K3s will work on a pi cluster, and it's easy to get started.
## Deployment idea #1
Put my Deno Fresh Blog in to k3s.
[How to Dockerize Fresh app](https://fresh.deno.dev/docs/concepts/deployment)
[Github docker build job](https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-container-registry) ?
How do ingress? Do I need an nginx ingress thingy pointed to fresh site?
## Setting up Raspberry Pis
All pis in my build are 'Raspberry Pi 4 Model B 8gb arm64' boards, with 32gb sandisk cards.
OS: Raspberry Pi OS Bookworm (~Debian 12)
I'm still figuring out k3s and networking and everything else.
### Needed software
`sudo apt update && sudo apt install curl vim python3-pip -y && sudo apt full-upgrade -y && sudo reboot`
### Patch Configs for k3s
```sh
# Add cgroups
sudo vim /boot/firmware/cmdline.txt
# Add this to the existing oneliner
cgroup_memory=1 cgroup_enable=memory
# close file
# Turn off / remove bluetooth
sudo vim /boot/firmware/config.txt`
# Disable bluetooth
dtoverlay=disable-bt
# Disable wifi
#dtoverlay=disable-wifi
# close file
sudo systemctl disable hciuart.service
sudo systemctl disable bluetooth.service
sudo apt purge bluez
sudo apt autoremove
sudo reboot
```
### Setting Static IPs
`ip r | grep default` for dns server ip
`ifconfig` to see device interaces
For Raspberry Pi OS Bulleyes or lower, change dhcpcd settings
```sh
sudo vim /etc/dhcpcd.conf
interface eth0
metric 300
static ip_address=/24
static routers=
static domain_name_servers=
interface wlan0
metric 200
static ip_address=/24
static routers=
static domain_name_servers=
# close file
sudo reboot
```
Raspberry Pi OS Bookworm uses Network Manager instead of dhcpcd.service, use `sudo nmtui` to set static ip's.
Or this
```sh
# for static wifi ip with imager configed wifi
sudo vim /etc/NetworkManager/system-connections/preconfigured.nmconnection
[ipv4]
address1=/24,
dns=;1.1.1.1;8.8.8.8;
dns-search=ht.home;
may-fail=false
method=manual
# close file
# for static ethernet
sudo vim /etc/NetworkManager/system-connections/Wired\ connection\ 1.nmconnection
[ipv4]
address1=/24,
dns=;1.1.1.1;8.8.8.8;
dns-search=ht.home;
may-fail=false
method=manual
# close file
sudo reboot
```
### Install k3s on master node
`curl -sfl https://get.k3s.io | K3S_KUBECONFIG_MODE="644" sh -s`
get your k3s token `sudo cat /var/lib/rancher/k3s/server/node-token`
### Install k3s on worker / agent nodes
`curl -sfL https://get.k3s.io | K3S_URL=https://:6443 K3S_TOKEN= sh -`
### ssh key
Copy the ssh key you want to use with ansible
```sh
# this should be on your main machine
ssh-copy-id -i ~/.ssh/id_rsa.pub pi@
```
