Rootless Containers/Pods that run systemd, Docker, and even Kubernetes

Hi HN, this is Cesar and Rodny, developers of an open-source container runtime called Sysbox, and co-founders of a startup called Nestybox (YC S20). We launched on HN almost a year ago and got excellent feedback then (https://news.ycombinator.com/item?id=24084758). Happy to say that over the past year, Sysbox has continued to gain traction, particularly for securing containers in production, CI/CD, and containerized dev environments. We wanted to announce an important new feature: integration between Sysbox and Kubernetes. As a quick refresher, Sysbox is a "runc" that…

Rootless Containers/Pods that run systemd, Docker, and even Kubernetes launched on July 27, 2021 with 10 votes, #1,371 of 3,502 launches that month and more than 75% of that year's launches.

In plain words

Sysbox is an open-source container runtime that enables rootless containers to run system software like systemd, Docker, and Kubernetes alongside traditional microservices. It enhances container isolation through Linux user-namespacing and filesystem virtualization, and integrates with Kubernetes for production deployments. Designed for developers and operators, it strengthens security in containerized environments, CI/CD pipelines, and development setups.

    Devbox is a command-line tool that lets you easily create isolated shells and containers. You start by defining the list of packages required by your development environment, and devbox uses that definition to create an isolated environment just for your application. In practice, Devbox works similar to a package manager like yarn – except the packages it manages are at the operating-system level (the sort of thing you would normally install with brew or apt-get).

  • 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! =)

    Devbox – Containers for better dev environments2025 · devbox.ar0.eu · ▲116

    I've been frustrated with dependency hell and clutter on my VPS from dev, so I built Devbox: a lightweight, open-source CLI tool that spins up isolated development environments using Docker. Each project runs in its own container, but your code stays in simple flat folders on the host machine—no messing with volumes or sync issues. Environments are disposable, so you can nuke and recreate them without losing your work. Key features: - Instant setup: `devbox init my-project` and you're in a fresh env with `devbox shell`. - Configurable via JSON: Define packages, services, and more in a…

    Hi again HN, we’re Arjun and Anirudh, founders of Signadot (YC W20). Signadot helps teams developing microservices test their changes using lightweight environments called “Sandboxes”. We use a relatively new approach, using traffic labeling (using OpenTelemetry) and request routing (using a Service Mesh) to isolate environments in a shared Kubernetes cluster. Today, we’re launching a new feature to help developers with local testing of microservices during the iterative development process. When we initially launched in September last year…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
