Docker Engine on Ubuntu 24.04 – Modern Containerization on a Stable LTS Platform
Docker Engine is the industry-standard runtime for developing, shipping, and running containers. On Ubuntu 24.04 LTS, Docker runs efficiently, leveraging the latest Linux kernel features, modern system libraries, and Canonical’s long-term support strategy—making it ideal for developers, DevOps teams, and enterprise container workloads.
Why Ubuntu 24.04 Is Ideal for Docker
Ubuntu 24.04 brings a host of under-the-hood improvements tailored to cloud-native environments:
- Linux Kernel 6.8+: Enhanced cgroup v2 support, io_uring optimizations, and better memory control
- systemd 253+: Reliable container process management and logging via
journald - AppArmor & Seccomp profiles: Default Mandatory Access Control and syscall filtering for containers
- Updated glibc and coreutils: For broader binary compatibility in custom container images
- Canonical’s LTS support cycle: Security updates through 2029, with ESM available until 2034
Ubuntu’s developer-focused design and large package ecosystem make it one of the most compatible base OSes for Docker workloads.
Docker Engine Overview
Docker Engine provides a lightweight, consistent way to build and run containerized applications. Key features include:
| Feature | Description |
|---|---|
| Image-based architecture | Use layers to build and reuse container images efficiently |
| Docker CLI/API | Unified command-line and REST interface for container management |
| OCI-compliance | Compatible with other container runtimes (e.g., containerd, CRI-O) |
| Volume and network support | Native tools to manage persistent storage and multi-host networks |
| Container orchestration | Compatible with Swarm Mode, and integrates with Kubernetes |
Docker is widely used for developing microservices, packaging legacy applications, and automating CI/CD pipelines.
Integration with Ubuntu 24.04 Ecosystem
Docker works seamlessly with Ubuntu-native technologies:
- ✅ Podman optionality: Docker and Podman can coexist (but not in parallel for the same containers)
- ✅ Snap and APT compatibility: Ubuntu’s packaging tools can be used alongside containerized apps
- ✅ Cloud-init: Automate Docker container deployment in cloud environments
- ✅ Systemd Units: Manage containers as services with native integration
- ✅ LXD compatibility: Ubuntu’s LXD container hypervisor can run alongside Docker
Use Cases on Ubuntu 24.04
Docker Engine is used across development and production environments for:
- Local dev environments: Quickly spin up services with no install conflicts
- Web application hosting: Node.js, Django, Flask, Laravel inside isolated containers
- CI/CD automation: GitHub Actions, GitLab CI, Jenkins pipelines
- Service-oriented architecture: Run microservices with independent scaling
- Legacy app packaging: Run older apps without touching host dependencies
- Hybrid cloud deployment: Seamless integration with AWS, Azure, GCP, and Shape.Host
Performance and Resource Control
Docker leverages Linux kernel features available in Ubuntu 24.04 for optimized runtime behavior:
| Feature | Docker Benefit |
|---|---|
| Cgroups v2 | Fine-grained control over CPU, memory, I/O per container |
| Seccomp filtering | Reduces syscall exposure for security |
| Namespaces | Complete process, user, and network isolation |
| OverlayFS | Efficient file system layer stacking |
| User namespaces | Optionally run containers with non-root mappings |
These features help ensure containers are both resource-efficient and secure—critical for multi-tenant or edge deployments.
Docker vs Other Container Runtimes on Ubuntu 24.04
| Runtime | Docker Engine | Podman | containerd |
|---|---|---|---|
| CLI Interface | Docker CLI | Docker-compatible | Requires custom tooling |
| Daemon | Runs as dockerd | Daemonless | Requires supervision |
| Rootless Mode | Available (needs config) | Native support | Limited |
| Kubernetes | Via Docker -> containerd | Compatible via CRI-O | Primary K8s runtime |
| Ecosystem | Huge, rich Docker Hub | Smaller | Focused on backend use |
Docker remains the most developer-friendly and mature solution, especially when targeting Docker Hub, Compose, or Docker Swarm ecosystems.
Security and Compliance
Ubuntu 24.04 enhances Docker’s security posture:
- AppArmor profiles: Limit container access to system resources
- Seccomp default profiles: Drop dangerous syscalls in containers
- Rootless Docker: Optional mode to run containers without root privileges
- Auditd integration: System-wide activity logging
- Immutable infrastructure: Treat containers as disposable, reproducible units
These features are essential for regulated industries, zero-trust infrastructure, and secure CI/CD pipelines.
Docker Engine on Ubuntu 24.04 combines the maturity and simplicity of Docker with the stability and modern toolchain of Ubuntu’s latest LTS release. It enables efficient container-based workflows for developers, sysadmins, and DevOps teams across all infrastructure types—from local dev machines to edge clusters and public clouds.
With excellent security defaults, OCI compliance, and seamless orchestration integration, Docker on Ubuntu 24.04 remains a first-class choice for container-native application delivery in 2025 and beyond.
Step 1: Create a Shape.Host Instance
Go to https://shape.host and log in to your account.
Click on “Create”, then select “Instance” from the menu.
Choose your preferred server location.
From the OS list, select Ubuntu 24.04 (64-bit).
Pick a plan with at least 2 CPUs, 4 GB RAM, and 20 GB SSD to ensure a smooth Docker experience.
Click “Create Instance”.
Once deployed, copy the IP address of your instance from the Resources section.
Step 2: Connect to Your Instance
If you’re using Linux or macOS:
Open a terminal and connect to your VPS:
ssh root@your-server-ip
Replace your-server-ip with the actual IP address of your Shape.Host instance.
If you’re using Windows:
You can either use the built-in Windows Terminal or PowerShell:
ssh root@your-server-ip
Or install PuTTY:
- Launch PuTTY.
- In the “Host Name” field, enter the IP of your instance.
- Port: 22, Connection Type: SSH.
- Click Open, accept the SSH key, and log in as
root.
Step 3: Update Your Package Index
apt update
This ensures all packages are up to date.
Step 4: Install Required Dependencies
apt install ca-certificates curl gnupg lsb-release
These are required for adding Docker’s GPG key and repository.
Step 5: Create the Keyrings Directory
install -m 0755 -d /etc/apt/keyrings
This is where the Docker GPG key will be stored.
Step 6: Add Docker’s Official GPG Key
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg
Step 7: Set Proper Permissions for the GPG Key
chmod a+r /etc/apt/keyrings/docker.gpg
This allows the APT system to read the key.
Step 8: Add Docker’s Repository
echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] \
https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | \
tee /etc/apt/sources.list.d/docker.list > /dev/null
This step enables Docker package installation from the official Docker repository.
Step 9: Update the Package Index Again
apt update
APT will now recognize Docker’s packages.
Step 10: Install Docker Engine and Required Tools
apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
This installs Docker Engine, the CLI, and support tools.
Step 11: Verify Docker Installation
docker --version
You should see Docker’s version output confirming a successful install.
Step 12: Run a Test Container
docker run hello-world
This pulls a test image and confirms Docker is functioning properly.
Step 13: (Optional) Remove Docker
If you need to uninstall Docker:
apt purge docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
Then delete Docker’s data:
rm -rf /var/lib/docker /var/lib/containerd
