CoreOS: Lightweight Linux Distribution for Clustered Deployments
CoreOS is a lightweight Linux distribution optimized for clustered deployments, security, and automation. It uses containers rather than packages and allows automated updates via continuous integration and delivery.
What is CoreOS?
CoreOS is an open-source lightweight operating system based on the Linux kernel and designed for providing infrastructure to clustered deployments. It focuses on security, consistency, and reliability.
Some key features of CoreOS include:
- Uses container-based application deployment and system componentization rather than a traditional Linux package-based approach. This allows for modular and flexible deployments.
- Automated updates via continuous integration and delivery with rollback capabilities if issues arise.
- A focus on security with signed images, secure boot capability, whitelisting of executables, and kernel hardening.
- Scaling and cluster management support via integration with cluster managers like Kubernetes.
- Consistent operating system instances across nodes in a cluster since applications run in containers.
CoreOS aims to be a minimal and optimized OS for running highly scalable deployments like large websites and cloud services. Its unique approach of using containers rather than packages and focus on automation makes it well-suited for building robust clustered infrastructure.
