slim - Build micro-vms from Dockerfiles

In plain words

Slim is a tool that creates lightweight virtual machines directly from Dockerfiles. It enables developers to build micro-VMs with minimal overhead by converting Docker container specifications into optimized VM images. The tool is designed for those who need the isolation and efficiency of virtual machines while leveraging existing Docker configuration files. It simplifies the VM creation process by eliminating the need to write separate VM provisioning scripts.

  I've built a nice home server OSApr 2026 · lightwhale.asklandd.dk · ▲194

  ohai! I've released Lightwhale 3, which is possibly the easiest way to self-host Docker containers. It's a free, immutable Linux system purpose-built to live-boot straight into a working Docker Engine, thereby shortcutting the need for installation, configuration, and maintenance. Its simple design makes it easy to learn, and its low memory footprint should make it especially attractive during these times of RAMageddon. If this has piqued your interest, do check it out, along with its easy-to-follow Getting Started guide. In any event, have a nice day! =)

  Layerfiles, Dockerfiles that build VMs2022 · ▲10

  Hey HN, I’m excited to show you Layerfiles, an OSS project which gives you a single binary to build microvms using a syntax that looks like a Dockerfile. The project is currently in alpha, but it’s already able to build a VM on Linux hosts. MicroVMs are like containers, but have several upsides: - They can run on any OS, so you don’t need to run a wrapper VM like Docker Desktop does. - They also let you keep processes running during a build (RUN BACKGROUND), so you can run a webserver or build server in the background. - You can generally run them rootless without any extra configuration.…

  I've built this to make it easy to host your own infra for lightweight VMs at large scale. Intended for exec of AI-generated code, for CICD runners, or for off-chain AI DApps. Mainly to avoid Docker-in-Docker dangers and mess. Super easy to use with CLI / Python SDK, friendly to AI engs who usually don't like to mess with VM orchestration and networking too much. Defense-in-depth philosophy. Would love to get feedback (and contributors: clear & exciting roadmap!), thx
