Project mention: Docker Sandboxes – Disposable, isolated sandboxes for AI agents | news.ycombinator.com | 2026-08-09
I'm very glad this now exists - fwiw almost a decade ago I worked on https://github.com/takeoff-env/takeoff as a solution for making it easier for hot reloading your stack which is thankfully redundant today, and funnily enough the list of problems you identify is also something I've been working on.
Recently I've also been working on a VM stack for an agentic platform using pre-build images with some cloud injection scripts that simplifies the deployment of a private agentic cluster - in the end I went with full VM with a 4vCpu/8gb for the main agent and 2vCPU/4Gb - only the main agent had docker-in-docker, the rest rootless docker but I agree it's still an elevated risk.
I'll definitely have to give this a spin and see if I can simplify it to one larger box with this solution.
