🚀 Docker Setup

Docker is like that friend who shows up at every party, but instead of eating all your snacks, it brings neat little containers of apps to run anywhere. 🎁

🛠️ Prerequisites

Section titled “🛠️ Prerequisites”
  • Internet access (no, your neighbor’s Wi-Fi doesn’t count)
  • A user with sudo privileges (aka, your inner superuser unleashed)

📦 Install Docker

Section titled “📦 Install Docker”

  1. Update your packages

    sudo nala update && sudo nala upgrade -y

    Because outdated packages are like expired milk. You could use them, but you’d regret it.

  2. Install dependencies

    sudo nala install ca-certificates curl gnupg lsb-release -y

  3. Add Docker’s GPG key

    sudo mkdir -m 0755 -p /etc/apt/keyrings
    curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

  4. Set up Docker repository

    echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

  5. Install Docker Engine

    sudo nala install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin -y

  6. Enable and start Docker

    sudo systemctl enable docker
    sudo systemctl start docker

✅ Test Docker

Section titled “✅ Test Docker”

Run the classic “Hello World” container to make sure you didn’t accidentally summon a digital demon. 👻

docker run hello-world

If you see “Hello from Docker!”, congrats! You now have a mini shipyard running in your server, and you’re officially cooler than 99% of people who think containers only exist in shipping yards. ⚓🚢
