How to Install Docker and Docker Compose on a Linux Dedicated Server (Ubuntu 24.04)

Running containerized applications on a Linux dedicated server is one of the smartest infrastructure decisions you can make today. Docker gives you lightweight, portable containers and Docker Compose adds the orchestration layer that lets you manage multi-container environments with a single configuration file.

This step-by-step guide walks you through installing Docker Engine and Docker Compose on Ubuntu 24.04 LTS (Noble Numbat) on a dedicated server, from a clean system to a fully working container runtime, with security, performance, and production readiness in mind.

Whether you are running a bare-metal dedicated server, a private cloud instance, or a high-performance VPS, the process is consistent and repeatable.

Why Docker on a Dedicated Server?

Dedicated servers are physical machines allocated entirely to your workloads, no noisy neighbors, no shared CPU or RAM. When you combine that raw performance with Docker's containerization model, you get a powerful foundation for modern DevOps pipelines, self-hosted applications, and scalable microservices.

Here is why running Docker on a dedicated Linux server is the preferred approach for teams serious about infrastructure:

  • Resource isolation without virtualization overhead: containers share the host kernel, so they use far less CPU and memory than full virtual machines.

  • Repeatable deployments: Docker images are portable. What runs on your local dev machine runs identically on your Ubuntu dedicated server.

  • Fast horizontal scaling: spin up multiple containers in seconds when demand spikes.

  • Simplified dependency management: each container bundles its own libraries, eliminating conflicts between services on the same machine.

  • Production-grade orchestration with Compose: Docker Compose lets you define your entire application stack, web server, database, cache, and queue in a single docker-compose.yml file.

If you are managing a dedicated server at COLO BIRD or any other hosting environment, Docker is the container runtime that most workloads depend on today.

Prerequisites

Before proceeding, make sure you have:

  • A dedicated server running Ubuntu 24.04 LTS (fresh install recommended)

  • Root or sudo privileges on the server

  • SSH access to the machine

  • A reliable internet connection from the server (to pull packages from Docker's repository)

  • Basic familiarity with the Linux command line

Note: This guide installs Docker Engine from Docker's official APT repository, not the older docker.io package available in Ubuntu's default repos. The official source gives you the latest stable release with full feature support.

Step 1 - Update Your Ubuntu System

Before installing any software on a dedicated server, always synchronize your package index and upgrade existing packages. This ensures a clean, consistent base and prevents dependency conflicts during installation.

sudo apt update && sudo apt upgrade -y

Once complete, you may want to reboot if a kernel update was applied:

sudo reboot

Reconnect via SSH after the reboot before continuing.

Step 2 - Install Required Dependencies

Docker's APT repository requires a few packages to fetch and verify packages over HTTPS. Install them now:

sudo apt install -y \
  ca-certificates \
  curl \
  gnupg \
  lsb-release \
  apt-transport-https

These tools handle certificate validation, HTTPS transport, and GPG key management, all needed for securely adding Docker's third-party repository.

Step 3 - Add Docker's Official GPG Key and Repository

Using packages directly from Docker's official repository, rather than Ubuntu's bundled version, guarantees you always install the latest stable Docker Engine. This is the correct and recommended approach for any production-grade dedicated server setup.

Create the keyring directory:

sudo install -m 0755 -d /etc/apt/keyrings

Download and add Docker's GPG key:

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | \
  sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

sudo chmod a+r /etc/apt/keyrings/docker.gpg

Add the Docker APT repository for Ubuntu 24.04:

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

Update the package index again to include Docker's repository:

sudo apt update

Step 4 - Install Docker Engine on Ubuntu 24.04

With the official repository in place, install Docker Engine, the CLI client, and the containerd runtime, the full container stack:

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

Here is what each component does:

Package Role
docker-ce Docker Engine, the core daemon
docker-ce-cli Command-line client (docker commands)
containerd.io Low-level container runtime
docker-buildx-plugin Advanced multi-platform image builds
docker-compose-plugin Integrated Compose support (docker compose)

Step 5 - Verify the Docker Installation

Confirm Docker Engine is running correctly on your Ubuntu dedicated server:

sudo docker run hello-world

A successful installation returns output similar to:

Hello from Docker! This message shows that your installation appears to be working correctly.

You can also check the installed version:

docker --version

Expected output:

Docker version 27.x.x, build xxxxxxx

And check the service status:

sudo systemctl status docker

You should see Active: active (running) in green.

Step 6 - Enable Docker to Start on Boot

On a dedicated server, you need Docker to automatically restart after any reboot or power cycle. Enable it as a systemd service:

sudo systemctl enable docker
sudo systemctl enable containerd

This ensures your containers and Docker daemon come back online automatically, critical for uptime on production dedicated infrastructure.

Step 7 - Run Docker Without sudo (Non-Root User)

By default, running Docker commands requires sudo. On a dedicated server where multiple developers or scripts interact with the daemon, it is best to add your user to the docker group:

sudo usermod -aG docker $USER

Apply the group change by logging out and back in, or run:

newgrp docker

Verify it works without sudo:

docker ps

Security Note: Users in the docker group effectively have root-level access to the host system via Docker. Only add trusted users to this group. Avoid running Docker as root in production; use dedicated service accounts.

Step 8 - Install Docker Compose on Ubuntu 24.04

If you installed the docker-compose-plugin in Step 4 (which you should have), Docker Compose is already available as a Docker CLI plugin. Confirm this:

docker compose version

Expected output:

Docker Compose version v2.x.x

Note on the old standalone binary: The legacy docker-compose (with a hyphen) binary has been deprecated. The current version is accessed as docker compose (space, no hyphen) and is integrated directly into the Docker CLI. For any new dedicated server setup, use the plugin version.

If for any reason you need to install it separately:

sudo apt install docker-compose-plugin

Step 9 - Verify Docker Compose Installation

Run a quick sanity check on Docker Compose:

docker compose version

Then confirm both Docker and Compose are talking to the same runtime:

docker info | grep -i server
docker compose ls

At this point, your Ubuntu 24.04 dedicated server has a complete, production-ready Docker environment installed and verified.

Step 10 - Deploy a Test Stack with Docker Compose

Let's validate your full setup by deploying a simple multi-container stack — a classic Nginx + Compose test.

Create a project directory:

mkdir ~/docker-test && cd ~/docker-test

Create the docker-compose.yml file:

nano docker-compose.yml

Paste the following:

version: "3.9"

services:
  web:
    image: nginx:latest
    ports:
      - "8080:80"
    restart: unless-stopped

Start the stack:

docker compose up -d

Verify the container is running:

docker compose ps

Test the response from Nginx:

curl http://localhost:8080

You should see the default Nginx HTML welcome page in your terminal — confirmation that Docker Compose is correctly orchestrating containers on your dedicated server.

Stop and clean up the test stack:

docker compose down

Docker Post-Installation Best Practices for Dedicated Servers

Getting Docker installed is only the beginning. Running containers reliably in production on a dedicated server requires a few additional steps that separate a solid setup from a fragile one.

Configure Docker Daemon Logging

Uncontrolled container logs can fill up your disk on a dedicated server faster than you might expect. Set log rotation in the Docker daemon config:

sudo nano /etc/docker/daemon.json

Add the following:

{
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "10m",
    "max-file": "3"
  }
}

Restart Docker to apply:

sudo systemctl restart docker

Set Up a Private Container Registry

For teams running multiple dedicated servers, a private registry (like Docker Registry or Harbor) lets you push and pull internal images without relying on Docker Hub rate limits.

Monitor Container Resource Usage

Use docker stats to get a live view of CPU, memory, and network consumption across all running containers:

docker stats

For more advanced monitoring on dedicated infrastructure, tools like Prometheus + cAdvisor + Grafana provide full container observability.

Keep Docker Updated

Regularly update Docker Engine on your dedicated server to get the latest security patches and features:

sudo apt update && sudo apt upgrade docker-ce docker-ce-cli containerd.io -y

Use Restart Policies

Always define restart policies in your Compose files so containers come back up after crashes or reboots:

restart: unless-stopped   # or "always" for critical services

Secure the Docker Socket

The Docker socket (/var/run/docker.sock) is a root-equivalent access point. Never expose it to untrusted processes or external networks without protection layers like Docker Socket Proxy.

Common Errors and How to Fix Them

Troubleshoot standard issues that may arise during installation or maintenance:

  • Error: Cannot connect to the Docker daemon

    Cause: The Docker service is not running.

    Fix:

    sudo systemctl start docker
    sudo systemctl status docker

  • Error: Permission denied when running docker commands

    Cause: Your user is not in the docker group.

    Fix:

    sudo usermod -aG docker $USER
    newgrp docker

  • Error: E: Package 'docker-ce' has no installation candidate

    Cause: Docker's official repository was not added correctly.

    Fix: Redo Step 3. Confirm the repository file was created:

    cat /etc/apt/sources.list.d/docker.list

    Then run sudo apt update again before installing.

  • Error: docker compose: command not found

    Cause: The docker-compose-plugin was not installed.

    Fix:

    sudo apt install docker-compose-plugin

  • Error: Got permission denied while trying to connect to the Docker daemon socket

    Cause: Group membership change has not taken effect in the current session.

    Fix: Log out and log back in, or run newgrp docker.

Frequently Asked Questions About Dedicated Server Security

Does Docker work on Ubuntu 24.04 LTS?

Yes. Docker Engine has full official support for Ubuntu 24.04 LTS (Noble Numbat). Always use Docker's official APT repository rather than the docker.io package in Ubuntu's default repos, as the latter may lag several versions behind.

What is the difference between Docker CE and Docker EE?

Docker CE (Community Edition) is the open-source version, fully functional for dedicated server deployments. Docker EE (Enterprise Edition) was a commercial product that has since been replaced by Docker Business/Desktop tiers. For self-hosted dedicated server use, Docker CE is the right choice.

Should I use Docker Compose v1 or v2?

Always use Docker Compose v2 (the docker compose plugin). The standalone v1 binary (docker-compose) is deprecated and no longer receives updates. The v2 plugin is faster, more feature-complete, and is the version installed in this guide.

Can I run Docker on a shared server or VPS?

Yes, but the advantages of Docker are most pronounced on a dedicated server where you control the entire hardware stack, kernel configuration, and resource allocation. Dedicated hosting eliminates the noisy-neighbor problem and gives your containers predictable performance.

How much RAM and CPU does Docker require?

Docker itself is extremely lightweight, the daemon typically uses under 100MB of RAM. Resource requirements depend entirely on the containers you run. A dedicated server with 8GB+ RAM and 4+ CPU cores is comfortable for most production workloads.

Is Docker secure on a dedicated server?

Docker has a strong security model, but it requires deliberate configuration. Key practices include running containers as non-root users, using read-only filesystems where possible, limiting capabilities, keeping images updated, and restricting access to the Docker socket. Docker's default settings are a starting point, not a finish line.

How do I uninstall Docker from Ubuntu 24.04?

sudo apt purge docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
sudo rm -rf /var/lib/docker
sudo rm -rf /var/lib/containerd
