How-tos

Table of contents

This section provides practical, task-based guidance for working with Docker Hardened Images (DHIs). Whether you're evaluating DHIs for the first time or integrating them into a production CI/CD pipeline, these topics cover the key tasks across the adoption journey, from discovery to debugging.

The topics are organized around the typical lifecycle of working with DHIs, but you can use them as needed based on your specific workflow.

Explore the topics below that match your current needs.
