Ask HN: MicroVM setup for VS Code Dev Container-like experience?

My current setup is just doing my entire development in a dev container that is running locally.

I open VS Code, I open the local folder in a dev container. The local folder gets mounted into container for persistent changes. The container dockerfile is my setup of dev dependencies. Within the container I can do whatever global installs I want that persist between sessions, and the project edits persist on host machine.

That works and I like the setup. I can run CLI codent agent in the terminal of VS Code, while still having good dev experience.

Now, I would like to have basically this flow but be MicroVM based, where the main thing I solve is allowing me to run docker inside that microvm, as docker-in-docker does not work well. Additionally if I could use secrets without them being exposed in the microvm itself, that would be amazing.

But I've spent a good amount of time checking different microvm's, and there's a few issues:

- A lot of them are designed for short ephemeral tasks, not a long running dev environment that easily persists and has separation of container persistence and host persistence

- I don't think they integrate with VS Code or other dev tools? Are you supposed to install vs code into the microVM itself, instead of having host VS Code interact with it?

- Docker released sandboxes which kinda does what I need, but it is JUST ai agents. And only the ones they support. You can't have your own custom environment where you do what you want.

So I am confused. There's tons of different solutions and none of them seem to work, all I want is to have Dev-Container like experience that is a bit more secure and can allow me to do Docker inside of it.
