Docker on Ubuntu 24.04

Docker is a powerful platform that enables developers to build, deploy, and manage containerized applications with ease. Running Docker on Ubuntu, a stable and popular Linux distribution, provides a reliable environment for developers to deploy, scale, and maintain applications seamlessly.

The Docker CLI uses the Docker REST API to control or interact with the Docker daemon through scripting or direct CLI commands. Many other Docker applications use the underlying API and CLI.

The Docker daemon (dockerd) listens for Docker API requests and manages Docker objects such as images, containers, networks, and volumes. A daemon can also communicate with other daemons to manage Docker services.

Dockers portability and lightweight nature also make it easy to dynamically manage workloads, scaling up or tearing down applications and services as business needs dictate, in near real time.

Docker Features

• Lightweight Containers: Docker containers isolate applications with minimal resource usage, ensuring efficiency and speed.
• Consistent Environment: Allows consistent environments across development, testing, and production, reducing compatibility issues.
• Efficient Resource Utilization: Unlike traditional virtual machines, Docker containers share the OS kernel, making them lightweight and fast.
• Simple Versioning and Rollback: Docker supports versioning for containers, making it easy to roll back to previous versions if needed.
• Easy Scalability: Docker Swarm and Kubernetes integration enables easy scaling of applications to handle increased traffic or workload.
• Broad Community and Library Support: Access a wide range of pre-configured Docker images on Docker Hub, reducing setup time.
• Continuous Integration and Continuous Deployment (CI/CD) Compatibility: Supports CI/CD pipelines for automated testing and deployment.
• Security and Isolation: Docker containers provide a secure, isolated environment, reducing risks associated with multi-tenant applications.
• Multi-Platform Support: Run containers across various platforms, including cloud, desktop, and server environments.
• Docker daemon (dockerd) manages Docker objects such as images, containers, networks, and volumes
• Docker registry to store Docker images
• REST API which specifies interfaces that programs can use to talk to the daemon and instruct it what to do
• Command line interface (CLI) client (the docker command)
• Namespaces provide a layer of isolation
• Control groups to limit applications to a set of resources
• Union file systems (UnionFS)
• Container format (libcontainer)
• Access to Docker hub public images

Docker on Ubuntu offers a practical alternative to traditional virtual machine deployments, competing with other container solutions like Podman, LXC/LXD, and rkt.
