Docker just released: https://github.com/docker/sbx-kits-contrib

If you’re using Docker Sandbox, this is pretty handy. It gives you pre-built “kits” (basically reusable env configs) so you don’t have to set up your agent environment every time.

Think:

• install tools (pip/npm/etc.)
• env vars + configs
• restricted network access
• credentials via proxy

All defined once and reusable across sandboxes.

Why this matters?

• no repeated setup for every agent run
• shareable + versioned environments
• better security (controlled access instead of full open env)

Early, but useful if you’re building anything serious with coding agents and running with Docker Sandbox
