Michael Irwin of Docker joins me to run through Gordon AI improvements, Docker Hardened Images and what's now free, Docker Sandboxes for running agents in proper isolation, Model Runner updates including MLX support on Mac, MCP Toolkit dynamic discovery, and the newly renamed Docker Agent with its GitHub Action for automating PR reviews and docs checks.

😇 My new GitHub Security workshop has launched! A free 2-hour workshop with hands-on labs to harden your repos and your workflows from common supply chain attacks. I'll cover how attackers are getting in, and then we'll lock down a sample repo so you know what needs to be done to protect your code. You'll leave with a deep understanding of risks and mitigations as well as a list of helpful tools to keep your repos safe, including my new "gasa" tool for scanning your repos and orgs.
