From Scratch to Self-Hosting

September 14, 2025

Here I post a step-by-step guide to have a home server from a newly bought minipc.

Let’s install Ubuntu

First of all, prepare a USB device for Ubuntu OS installation. Thanks to Ventoy, we can download Ubuntu and create a bootable USB drive for it. Then, just install Ubuntu, alongside Windows if your minipc has it already installed or just erase the disk. I prefer the later to have more usable memory for my stuff.

Things to install in Ubuntu

ℹ️

To update all packages, run:

sudo apt update
ℹ️

if you ever need to uninstall any package, run:

sudo apt purge whatever_package -y
sudo apt autoremove

Here I have listed all commands needed to install all my stuff in my minipc to have it working as a home server:

Curl 

sudo apt-get install curl

Tailscale 

curl -fsSL https://tailscale.com/install.sh | sh
sudo tailscale up

Then, to make sure you can connect to your server, run:

sudo systemctl status ssh

If inactive (dead), then run:

sudo systemctl enable --now ssh

This will start the service immediately and ensure it starts on boot. After all, you will be able to connect to you server terminal by running in cmd or Powershell:

ssh username@100.x.y.z

Podman 

apt install podman
podman --version # just to make sure it is correctly installed

Docker 

curl -fsSL https://get.docker.com -o get-docker.sh
sh get-docker.sh
docker version

After installation, check if Docker gets started at system boot:

sudo systemctl is-enabled docker

It should prompt as output enabled. If not, run:

sudo systemctl enable docker

Test your installation by running:

docker run hello-world

Then, install Docker Compose 2:

DOCKER_CONFIG=${DOCKER_CONFIG:-$HOME/.docker}
mkdir -p $DOCKER_CONFIG/cli-plugins
curl -SL https://github.com/docker/compose/releases/download/v2.27.0/docker-compose-linux-x86_64 -o $DOCKER_CONFIG/cli-plugins/docker-compose
sudo chmod +x $DOCKER_CONFIG/cli-plugins/docker-compose

If the last command line returns “No such file or directory”, then you have to add to your system’s PATH where to find docker-compose:

nano ~/.bashrc

Then, add at the end of the file:

export PATH=$PATH:~/.docker/cli-plugins

Save the file (Ctrl+O), exit the editor (Ctrl+X) and apply the changes to your current session by sourcing the file:

source ~/.bashrc

Finally, start and run Portainer, a graphical user interface (GUI) that sits on top of your Docker setup. By running this command, you’re essentially installing a user-friendly control panel:

docker run -d -p 8000:8000 -p 9000:9000 --name=portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce
docker restart portainer

Now, navigate to server_IP:9000 and you can create your admin user.

htop 

sudo apt install htop

Git

Git should have been installed by now, but if not:

sudo apt update
sudo apt install git

To clone your repositories:

git clone git@github.com:your_username/your_repo_ssh_url.git

Now, it’s time to configure your Git user information:

git config --global user.name "Your Name"
git config --global user.email "youremail@example.com"

Replace “Your Name” and “youremail@example.com” with your GitHub name and email.

Once you have configured your Git information, choose an authentication method; I have chosen SSH key:

ssh-keygen -t ed25519 -C "youremail@example.com"

Then, copy the output of the following command line:

cat ~/.ssh/id_ed25519.pub

and go to Github > Settings > SSH and GPG Keys > New SSH Key > Key field. Paste the output there and give it a title. After all, test the connection:

ssh -T git@github.com

To sync all your projects without having to be logged in, just create the pull script and timer, then run the timer with systemd. Follow these steps:

Create the script:

sudo nano /usr/local/bin/git-pull-all

Paste the following code:

#!/bin/bash

# Path to your projects directory
PROJECTS_DIR="/home/jlleongarcia/projects"

# Check if the directory exists
if [ ! -d "$PROJECTS_DIR" ]; then
  echo "Projects directory not found at $PROJECTS_DIR"
  exit 1
fi

# Change to the projects directory
cd "$PROJECTS_DIR" || exit

# Loop through each directory and pull the latest changes
for repo in */; do
  if [ -d "$repo/.git" ]; then
    echo "Syncing $repo..."
    cd "$repo"
    git pull
    cd ..
  fi
done

Make the script executable:

sudo chmod +x /usr/local/bin/git-pull-all

Create a systemd Service:

sudo nano /etc/systemd/system/git-sync.service

Add the service configuration:

[Unit]
Description=Git synchronization service
After=network.target

[Service]
ExecStart=/usr/local/bin/git-pull-all
User=jlleongarcia
Group=jlleongarcia

[Install]
WantedBy=multi-user.target

Create a systemd Timer:

sudo nano /etc/systemd/system/git-sync.timer

Add the timer configuration:

[Unit]
Description=Runs git-sync.service every day at 8am

[Timer]
OnCalendar=*-*-* 08:00:00
RandomizedDelaySec=15m
Persistent=true

[Install]
WantedBy=timers.target

Finally, enable and start the Timer:

sudo systemctl daemon-reload
sudo systemctl start git-sync.timer # Start the Timer
sudo systemctl enable git-sync.timer # Enable the timer to run on boot

To check the status of your timer, run:

sudo systemctl status git-sync.timer

uv 

curl -LsSf https://astral.sh/uv/install.sh | sh

Then, restart your terminal or run:

source $HOME/.local/bin/env

Develop your projects using VSCode Remote - SSH

If you are familiar to VSCode, you can use it to develop your projects directly on your home server, save it to the server’s project directory, and then run it directly in a terminal within VS Code that is connected to the server.

To do so, you will need to install the “Remote - SSH” extension in VSCode. Once installed, you can connect to your server by clicking on the green “Remote Explorer” icon in the activity bar on the left, then selecting “SSH Targets” and clicking the “+” icon to add a new SSH host.

You will be prompted to enter the SSH connection command, which will be similar to ssh username@100.x.y.z. After successfully connecting, VSCode will open a new window connected to your server, allowing you to browse files, edit code, and run terminals as if you were working locally on the server.

Other apps to be included as optional

Umami + Cloudflare to get web analytics

The process involves two main phases: setting up the Umami server and connecting it via the Cloudflare Tunnel. Most people use Docker for the Umami server setup as it simplifies deployment.

  1. Create the Umami Setup Files: Create a directory for Umami and inside it paste:
openssl rand 30 | openssl base64 -A
  1. Create a .env file:
nano .env

and paste the generated code:

# Umami Application Secret
UMAMI_SECRET=<PASTE_YOUR_GENERATED_SECRET_HERE>

# Database Configuration (Using PostgreSQL for simplicity)
DATABASE_URL=postgresql://umami:umami@umami-db:5432/umami
  1. Create the docker-compose.yml file:
nano docker-compose.yml
version: '3.8'

services:
  umami:
    image: ghcr.io/umami-software/umami:postgresql-latest
    container_name: umami
    restart: unless-stopped
    ports:
      - "127.0.0.1:3000:3000"
    depends_on:
      - umami-db
    environment:
      - DATABASE_URL=${DATABASE_URL}
      - HASH_SALT=${UMAMI_SECRET}
      - APP_SECRET=${UMAMI_SECRET}
    # Important: Umami runs on port 3000 inside the container. 
    # We will use this internal port with the Cloudflare Tunnel.

  umami-db:
    image: postgres:15-alpine
    container_name: umami-db
    restart: unless-stopped
    environment:
      POSTGRES_USER: umami
      POSTGRES_PASSWORD: umami
      POSTGRES_DB: umami
    volumes:
      - ./umami_data:/var/lib/postgresql/data

After creating all these files, run the following command to start the Umami Containers:

docker-compose up -d

Then, install the cloudflared Daemon:

wget https://github.com/cloudflare/cloudflared/releases/latest/download/cloudflared-linux-amd64.deb && sudo dpkg -i cloudflared-linux-amd64.deb

Run the command:

cloudflared tunnel login

The command will output a URL. Copy this URL and paste it into a web browser on your computer. The browser will prompt you to log in to your Cloudflare account. Once logged in, select the domain you want to use for the Tunnel and click Authorize.

Next, create the Tunnel in the Cloudflare Dashboard and define the Umami Service.

Finally, run the tunnel by:

cloudflared tunnel run <YOUR-TUNNEL-NAME>

and paste the following command just before the closingtag:

<script 
    async 
    src="https://<YOUR_UMAMI_DOMAIN>/script.js" 
    data-website-id="<YOUR_WEBSITE_ID>">
</script>

In order to test if your containers are up, run:

docker ps -a --format "table {{.Names}}\t{{.Status}}\t{{.Ports}}"

Installing an external SSD

After the physical installation of the external disk, you need to tell Linux how to use this new bunch of space.

  1. Identify the Drive

    Open your terminal and run:

    lsblk

    Look for a new disk that is approximately the size of the disk you bought. It will likely be labeled something like /dev/sdb.

  2. Format the Drive

    We will use ext4, the most stable and standard filesystem for Linux servers.

    # Replace 'sdb' with your actual drive letter found in the previous step
sudo mkfs.ext4 /dev/sdb

  3. Create a Mount Point

    We don’t want to manually mount the drive every time the minipc restarts. Choose a location where your data will live.

    sudo mkdir -p /mnt/nextcloud_data

  4. Get the UUID

    Linux identifies drives best by their UUID (Unique ID), which doesn’t change even if you swap cable ports.

    sudo blkid /dev/sdb

    Copy the long alphanumeric string inside the quotes (e.g., UUID=“550e8400-e29b-…”).

  5. Edit the File System Table

    sudo nano /etc/fstab

    Add this line to the bottom of the file (replace the UUID with yours):

    UUID=your-uuid-here /mnt/nextcloud_data ext4 defaults 0 2

    Save and exit (Ctrl+O, Enter, Ctrl+X).

  6. Test the Mount

    sudo mount -a

    If no errors appear, your SSD is now active at /mnt/nextcloud_data. However, if it returns “mount: (hint) your fstab has been modified but systemd still uses the old version; use ‘systemctl daemon-reload’ to reload”, no stress—this is a perfectly normal informational message on modern Linux systems. Just reload the systemd manager configuration:

    sudo systemctl daemon-reload

    and mount the drive again.

    sudo mount -a

Git notes

When working with branches, if one branch isn’t up to date any more with main, there are two options:

  • Option A — Merge main into your branch (simpler, safer):

    git checkout your-other-branch
git fetch origin
git merge origin/main

    Creates a merge commit, but no risk of rewriting history.

  • Option B — Rebase your branch on top of main (cleaner history):

    git checkout your-other-branch
git fetch origin
git rebase origin/main

    Replays your commits on top of the updated main — linear history, no merge commit. Since files don’t overlap, no conflicts expected.
