Chainguard: Building Secure Container Images

Download MP3
Bret and Nirmal are joined by Dan Lorenc from Chainguard to walk them through Chainguard's approach to building secure, minimal container images for popular open source software.

They discuss why it is important to have secure and minimal container images. Dan explains how Chainguard helps remove the pain of CVEs, laggy software updates and patches and much more. Chainguard is now available also on Docker Hub.

They spend the first part of the show talking about the week's big news: the XZ supply chain attack, and Dan was the best man to explain it. They also touch on CVEs, things you can do to reduce the attack surface, SLSA, and more during this jam-packed show.

Be sure to check out the live recording of the complete show from April 4, 2024 on YouTube (Ep. 261).
