Fast Way: How To Install Docker and Docker Compose on Linux

-- update packages: 
sudo apt update

-- install prerequisite packages:
sudo apt install apt-transport-https ca-certificates curl software-properties-common

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

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

-- Update packages again:
sudo apt update

-- Check Docker repo:
apt-cache policy docker-ce

-- install Docker
sudo apt install docker-ce

-- Check that it’s running:
sudo systemctl status docker

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin

-- Download docker compose v2.11.0
mkdir -p ~/.docker/cli-plugins/
curl -SL https://github.com/docker/compose/releases/download/v2.11.0/docker-compose-linux-x86_64 -o ~/.docker/cli-plugins/docker-compose

-- Permissions to docker compose:
chmod +x ~/.docker/cli-plugins/docker-compose

-- Verify the installation
docker compose version

sudo apt-get install docker-compose-plugin

-- If you prefer the old style, create an alias: 
alias docker-compose='docker compose'
