Newsletter Title

Docker Sandboxes Put CI Agents Behind a Smaller Boundary

Intro

Docker’s GitHub Agentic Workflows integration gives coding agents a microVM sandbox with a private Docker daemon, making CI automation more useful without handing it the whole runner.

Takeaways

  • GitHub Agentic Workflows, the gh-aw GitHub CLI extension, added Docker Sandboxes as a supported agent runtime in July 2026.
  • Useful coding agents need more than read-only repository access.
  • GitHub Agentic Workflows starts from a Markdown workflow file.
  • The next useful evolution is policy portability.
