What is ubuntu image?

The ubuntu image contains the popular Debian-based Linux distribution tailored for containers. It provides a stable and secure foundation for building custom application images, offering a balance between usability, compatibility, and size. Ubuntu is one of the most widely used Linux bases for Docker and Kubernetes workloads because of its familiarity, extensive package ecosystem, and strong security update cadence.

This image is commonly used to build and run software in production, development, or CI/CD environments that depend on Ubuntu’s package repositories (apt) or kernel compatibility. It’s also used for debugging, testing, and as a base for language runtimes (like Python, Node, or Go). Its reliability, consistent updates, and large community support make it a standard choice for both developers and enterprises.

How to use this image

The ubuntu image can be used interactively to explore a Linux shell, as a base for custom builds, or in automation pipelines.

Run interactively:

docker run -it ubuntu bash

Run a single command:

docker run ubuntu echo "Hello, world"

Use as a base image in a Dockerfile:

FROM ubuntu:24.04
RUN apt-get update && apt-get install -y curl vim
COPY . /app
CMD ["bash"]

Logs are output directly to stdout and stderr. The container will exit automatically when the command completes unless run interactively.
