This video is a recording of a Chainguard Learning Labs livestream that happened on Thursday, August 28.
Legacy Dockerfiles often expose organizations to unnecessary security risks, inefficiency, and compliance gaps – issues that especially impact DevOps teams tasked with building and maintaining reliable CI/CD workflows. As supply chain attacks surge and regulatory demands tighten, transforming vulnerable containers is now mission critical. This lab shows how Chainguard’s DFC CLI streamlines the process of converting legacy Dockerfiles to secure, minimal containers, empowering DevOps to proactively safeguard software delivery without time-consuming manual rewrites.
