If you're just getting into Docker (maybe for hosting your own game servers, dev work, or modding tools), here's a simple guide to get Docker installed on your system.

Download Docker Desktop
➡️ Docker Desktop: The #1 Containerization Tool for Developers | Docker​

  1. Run the installer
    Follow the prompts. Docker will ask you to enable WSL 2 if it isn’t already.
  2. Restart your computer if asked
  3. Open CMD or PowerShell, type:

Code: 
docker --version
You should see something like:
Code: 
Docker version 24.x.x, build abc123

Download Docker Desktop for Mac
➡️ Docker Desktop: The #1 Containerization Tool for Developers | Docker​

  1. Open the .dmg, drag Docker into Applications
  2. Launch Docker Desktop, allow permissions if prompted
  3. Open Terminal, type:
Code: 
docker --version

How to Install Docker on Linux (Ubuntu/Debian)​

Paste these into your terminal:
Code: 
sudo apt update
sudo apt install apt-transport-https ca-certificates curl software-properties-common -y

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker.gpg

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

sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io -y
Then:
Code: 
sudo systemctl enable docker
sudo systemctl start docker
docker --version
Optional: Run Docker without sudo:
Code: 
sudo usermod -aG docker $USER
Then log out and back in, or reboot.

Test it works:
code]
docker run hello-world
[/code]

You should get a success message!
