Docker

Docker provides a platform for building, sharing, and running containerized applications, handling environment setup so developers can focus on code. It offers a set of open‑source, Apache‑2.0‑licensed hardened images that include complete SBOMs and SLSA Level 3 provenance, aiming for near‑zero known vulnerabilities. The catalog contains minimal, distroless Debian and Alpine images that reduce footprint and attack surface, and it supports extended lifecycle security for images that have reached end‑of‑life.

The system is targeted at developers and teams that need a reliable, secure container ecosystem for a wide range of workloads, from standard applications to AI agents and machine‑learning pipelines. It includes features such as signed builds, customizable images, and built‑in isolation, with optional enterprise options for service‑level agreements, compliance, and long‑term CVE remediation.

Docker is an open‑source, free‑tier tool positioned as a stable, developer‑focused solution for container application development, offering a growing collection of verified images and a streamlined workflow for creating and deploying software across environments.
