The Compose Native To Docker: Why You Should Care About Docker Compose V2

Docker Compose has long been the secret sauce behind orchestrating multi-container Docker applications, especially in development or single server systems where swarm might be an overkill. With Compose V2, the experience just got smoother. Unlike the standalone docker-compose binary of the past, Compose V2 is now natively integrated into the Docker CLI — making it faster, more consistent, and easier to maintain.

No more juggling between two command-line tools. Now, everything is neatly under the docker umbrella:

docker compose up

Yes — no hyphen. Just power.

Here’s how to install it if you are on older Ubuntu desktops.

Step 1: Remove Old Docker Versions (Clean Slate)

To avoid conflicts and ensure you’re using the freshest stack, let’s purge the old Docker setup:

sudo systemctl stop docker docker.socket
sudo apt-get purge -y docker-ce docker-ce-cli containerd.io docker-compose-plugin docker-compose
sudo rm -rf /var/lib/docker /var/lib/containerd /etc/docker
sudo apt-get autoremove -y

Step 2: Install the Latest Docker + Compose V2

Here’s how to set up the newest Docker Engine and Compose plugin from the official Docker repositories:

# Setup repository
sudo apt-get update
sudo apt-get install -y ca-certificates curl gnupg lsb-release

sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/$(. /etc/os-release && echo "$ID")/gpg | \
  sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

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

# Install the full stack
sudo apt-get update
sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

✅ Step 3: Confirm It’s Working

Make sure Docker and Compose are installed and functional:

docker version
docker compose version

💡 Why Compose V2 is a Big Deal

  • Unified CLI – No need to install and manage a separate binary.
  • Better performance – Tighter integration with Docker internals.
  • Improved support for new Docker features – BuildKit, GPU support, secrets, and more.
  • Plugin architecture – Clean, modular upgrades in future versions.
  • Cross-platform – Works out of the box with Docker Desktop on macOS/Windows, and with CLI on Linux.
