logging so i don’t forget what i did; to eventually try to automate this

flash usb drive with linux mint cinnamon 22.1 using balena etcher

brew install --cask balenaetcher

alt + power button on macbook pro 2015 to show boot drives, select correct drive
start linux mint, then install from the desktop – this let me skip needing a ethernet connection to install the wifi drivers; was also prompted to install codecs so i can actually view youtube videos. it’s quite performant, amazing
install ssh

  sudo apt update && sudo apt upgrade
  sudo systemctl status ssh

  sudo systemctl enable ssh
  sudo systemctl start ssh

once installed, go to power management and change default “suspend” when in clamshell mode
dhcp reservation - this can be done thru asus gui. handy commands ip addr to check success and device mac.

  1: lo
  loopback interface, virtual network device used by your system to communicate with itself (localhost, 127.0.0.1), every linux system has it.
  2: wlp3s0
  wireless network interface; the name wlp3s0 follows the modern "predictable network interface naming" scheme:
  wl = wireless LAN
  p3 = PCI bus 3
  s0 = slot 0
  3. eth0 
  ethernet

note asus router fixes the first 3 bits, server is @ 200.

batteries are completely dead, so server needs to be moved otherwise the cat tends to disconnect the cable

ssh keygen

  # on the mac, also name your key otherwise you kena
  ssh-keygen -t ed25519 -C "macbook-to-mint-master"

  # note filename: <users>/.ssh/ansible_key

  ssh-copy-id <user@xx.xx.xx.200>

subsequent logins are just ssh user@xx.xx.xx.200, i can make an alias but i’d probably forget if i did

you can always sudo whoami to check if account is root lol. linux mint comes with python3 installed by default on cinnamon

little ansible playbook for k3s (i could just write the install script, but there’s nothing like fooling around to learn)

there’s https://github.com/k3s-io/k3s-ansible for reference

key terms:

control node: where ansible is installed, where i run commands from. this is my mac.
inventory: describe the things you wanna manage so ansible can use them ig?
managed node: in this case, where i want to put k3s

set up inventory.ini similar to the tutorial, then

ansible-playbook -i inventory.ini install-k3s.yaml -K
BECOME password:

use kubectl’s built in merge to uh, merge configs so you can kubectl from outside

# check your external k3s config is pointing to its ip, this probably needs to be reworked eventually....

# run this within the repo directory

cp ~/.kube/config ~/.kube/config.backup

KUBECONFIG=k3s-config.yaml kubectl config view --flatten > ~/.kube/config.new

mv ~/.kube/config.new ~/.kube/config

it would be MUCH better if i’d renamed the k3s env to something else, instead of like “default”, but another time

modify mac’s etc/hosts file to point to pihole.local for dashboard >__> i need to uh… do this better
try to update local device’s dns servers first

16:52:14 in ~ using ☁️ terraform using ☁️  default/
➜ scutil --dns | grep nameserver
  nameserver[0] : 192.168.50.200
  nameserver[0] : 192.168.50.200

write manifests to deploy stuff - pihole vs adguard home
