Docker, Inc. Adds More Than A Thousand Free Hardened Container Images
Cloud Native Now, Wednesday, December 17th, 2025
Docker, Inc. today revealed it is making more than 1,000 hardened container images available under an open source Apache 2.0 license to enable application developers to build more secure cloud-native applications.
Available via Docker Hub, the Docker Hardened Images (DHI) being made available for free are built on Linux distributions of Debian and Alpine to provide a complete set of images that can be readily deployed.
Additionally, Docker has extended its generative artificial intelligence (AI) tool, dubbed Docker AI Assistant, to now be able to scan existing containers and recommend and apply equivalent hardened images. Docker is also extending its hardening methodology to Model Context Protocol (MCP) servers, starting with hardened versions of more than ten servers, including implementations from Grafana, MongoDB and GitHub.
