A lightweight tool for building and running layered root filesystems as semi-isolated processes.
Plash is a lightweight containerization tool that builds and runs layered root filesystems as semi-isolated Linux processes. It solves the problem of over-engineered container solutions by providing a minimalist, integrated alternative that shares host resources like network and home directories. Unlike traditional containers, Plash containers behave like normal processes, making them simpler and more resource-efficient.
Developers and system administrators who need a lightweight, minimalist container tool for building and running layered filesystems without the overhead of full container isolation. It's ideal for those who prioritize simplicity, host integration, and long-term maintainability.
Developers choose Plash over alternatives like Docker because it offers a significantly simpler, less bloated interface and avoids vendor lock-in and overengineering. Its process-like containers provide better integration with the host system, sharing resources naturally, while its minimalist design ensures it remains maintainable and timeless.
Build and run layered root filesystems.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Requires only make, cc, and Linux kernel >=5.11, with no complex daemons or setuid helpers, making it lightweight and easy to deploy.
Containers run as normal Linux processes, sharing host resources like network access, home directories, and /tmp, enabling seamless interaction with the system.
Supports importing images from Docker, LXC, URLs, and tar files, and exporting to directories or tar archives, offering flexible image management.
Embraces minimalism with a focus on being a timeless, finished product that requires no maintenance, as outlined in the development guidelines.
README explicitly states there is no security-relevant isolation; containers have the same access rights as the caller, making it unsafe for untrusted code.
Lacks advanced container engine capabilities like orchestration, networking controls, and resource management, which are standard in tools like Docker.
Requires Linux kernel >=5.11 and has known issues running inside Docker containers unless privileged, reducing compatibility and flexibility.
