RancherOS: Minimalist Linux Distribution for Docker Containers
A secure, scalable, and simplified way to run Docker containers, RancherOS optimizes the OS for seamless configuration through Docker Compose files, running entire OS as containers.
What is RancherOS?
RancherOS is a Linux distribution purpose-built for running Docker containers. It runs the entire OS as Docker containers and simplifies system configuration through Docker Compose files. Key features of RancherOS include:
- Minimalist OS: Removes unnecessary libraries and services, reducing attack surfaces and optimization for container workloads.
- Everything runs as containers: The kernel, system services and user processes all run as containers managed by Docker.
- Simple configuration: Docker Compose files configure the entire system's services.
- Latest stable Docker version: Ships with the latest Docker engine and container networking built-in.
- Designed for security: Runs containers as non-root users and supports Docker Seccomp security profiles.
- Lightweight: Consumes minimal system resources leaving room for container workloads. Image is only 55MB.
RancherOS is ideal for running containerized workloads in development and production. It simplifies configuration and management of infrastructure running Docker. The minimalist design also improves security and reduces resource utilization.
