Getting started¶
- Boot to rescue
- Run
installimageand edit the storage to use ~80/100etc gb for root (/) and the remainder for /home. In this case giving ~28tb of storage for /home. - Let it run
First boot¶
Make sure the storage is correct.

Check the status of the raid build:

Next, setup user.
useradd bl
passwd bl {passwd}
usermod -aG wheel bl
pacman -S sudo vi vim git curl
visudo {edit wheel to have permisisions}
pacman -Syu (probably not needed, but good to make sure the image wasn't old.)
reboot
SSH with your new user. Test permissions -> sudo df -h /
Now install system tools and docker. - pip3: for python3 modules - docker: read more here - docker-compose: read more here - nload: watch network traffic - vnstat: log the network traffic (throughput and data over time) - fail2ban: block repeated ssh login attempts (helps to stop bots) - htop: monitor cpu and memory usage
sudo pacman -S zsh python-pip docker docker-compose vnstat nload htop fail2ban
Now start services and add user to docker group.
sudo systemctl enable docker
sudo systemctl start docker
sudo systemctl enable fail2ban
sudo systemctl start fail2ban
sudo systemctl start vnstat
sudo systemctl enable vnstat
sudo usermod -aG docker bl
Reboot.
Login again. Test docker running -> docker run hello-world
Expected output:
$ docker run hello-world
Unable to find image 'hello-world:latest' locally

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash

Now build folder structure. I use the following:
/home
|--/docker
|--/docker/imageName/
|--/docker/imageName/docker-compose.yml
/home
|--/dev
|--/dev/Homelab-Setup/
/home
