24 alternatives to Docker-boot – Run a system from RAM without LiveCD

How often do you screw up the system so much you have to reformat the disk (without losing data) to fix it? Well, sometimes I do, and sometimes I can't be bothered to burn a live ISO onto a USB stick. There's initramfs, but it's hardly a pleasant environment, with network configuration and all. My go-to solution has typically been to create a chroot with busybox and a few utilities in /tmp, chroot into it, and then kill services that use the solid drive so that I can unmount it. That's an error-prone process, and sometimes systemd itself uses disk, so you can't unmount the drive despite…

Docker-boot enables users to run a complete system environment from RAM without needing to create a LiveCD or USB stick. It uses Docker images as a base to create a customizable chroot environment, automatically… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Docker-boot – Run a system from RAM without LiveCD launched in 2024; newer entries below may have overtaken it.

    I got tired of the push-to-registry/pull-from-registry dance every time I needed to deploy a Docker image. In certain cases, using a full-fledged external (or even local) registry is annoying overhead. And if you think about it, there's already a form of registry present on any of your Docker-enabled hosts — the Docker's own image storage. So I built Unregistry [1] that exposes Docker's (containerd) image storage through a standard registry API. It adds a `docker pussh` command that pushes images directly to remote Docker daemons over SSH. It transfers only the missing layers, making it…

    It is fairly simple, but useful for non-power users: a statically-linked Qt app that gracefully edits Windows Boot Manager to do a reboot-once into GRUB, which in turn launches ZorinOS live/installer from disk loopback. I needed to make a custom initramfs with dislocker in it, and to squeeze it a little (default Windows EFI partition is not so big). Currently my biggest issue is that systemd is unable to shut down gracefully when rootfs is mounted from such a deep loop stack. The other is that installing to full disk crashes right after it successfully damages the partition table. I…

    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! =)

    Dockerized is like npx for unix tools: Run popular cli tools without installation. Example: dockerized npm init dockerized python2 somescript.py Run an older version of a tool: NODE_VERSION=15.0 dockerized node Use cases: - Maintaining multiple versions of an app - Installing without polluting host machine - Quickly run some commands you may not have installed Features: - intuitive use. Just the original command, but with 'dockerized' in front. - dockerized apps can access the current directory and read/modify files, just like native apps. - no need to know which docker image this…

    This project addresses the inefficiencies of traditional Dockerfile-based container builds where each customization layer creates storage bloat through duplicate dependencies from repeated apt-get install commands, network inefficiency from redundant package downloads across different images, and slow iteration cycles requiring full rebuilds of all previous steps. Our solution enables building minimal base images from scratch using debootstrap that precisely include only required components in the initial build, while allowing creation of specialized variants (Java, Kafka, etc.) from these…

    Hey HN! I just released go-nbd, a lightweight Go library for effortlessly creating NBD servers and clients. Its a neat tool for creating custom Linux block devices with arbitrary backends, such as a file, byte slice or what I'm planning to use it for, a tape drive. While there are a few partially abandoned projects like this out there already, this library tries to be as maintainable as possible by only implementing the most recent handshake revision and baseline functionality for both the client and the server, while still having enough support to be useful. I'd love to get your feedback :)

    I built GRSH because I wanted a modern, memory-safe shell that feels native to FreeBSD but works seamlessly on macOS. While there are many shells out there, GRSH is my take on a minimal, fast, and secure command interpreter written entirely in Rust. It's designed for users who want the safety guarantees of Rust without the overhead of more bloated alternatives. I'm currently working on the official FreeBSD port. I’d love to get feedback on the shell's behavior and performance from the community. Github: https://github.com/antoniomalara301289/grsh

    This project contains no code from Linux, BSD, Minix, or any other OS. Everything up until this point is written entirely from scratch, including a pure microkernel (that only implements multiprocessor priority scheduling, memory management, and interprocess communication), a work-in-progress implementation of the standard C library, and a variety of servers that provide drivers and other essential OS functionality. At the time of writing this post, the servers provide drivers for the keyboard, NVMe SSDs (that works on real hardware), a Unix-like virtual file system (with a single root…
