Install Docker

Windows

1. Download Docker Desktop:

   • Go to: https://www.docker.com/products/docker-desktop/

   • Click "Download for Windows"

   • Run the installer

2. Install:

   • Follow the installation wizard

   • When it asks about WSL 2, say Yes (it will install it if needed)

   • Restart your computer when asked

3. Start Docker Desktop:

   • Look for Docker Desktop in your Start menu

   • Open it

   • Wait for it to start (you'll see a whale icon in your system tray)

   • The whale icon should be steady (not animated) when it's ready

4. Verify it works:

   • Press Windows key, type powershell, press Enter

   • Type: docker --version

   • Press Enter

   • You should see something like: Docker version 24.x.x

   • If you see an error, Docker isn't installed correctly

Linux

Install Docker:

*Ubuntu/Debian*

sudo apt update

sudo apt install docker.io docker-compose

sudo systemctl start docker

sudo systemctl enable docker

Add your user to docker group (so you don't need sudo)

sudo usermod -aG docker $USER

Log out and log back in for the group change to take effect

Verify it works:

docker --version

You should see a version number. If not, Docker isn't installed correctly.
