CoreOS

Key components to secure, simplify and automate your container infrastructure

CoreOS

The container optimized OS

We are building minimal Operating Systems (RHEL CoreOS, Fedora CoreOS) focused on running containerized workflows, with a focus on security, scalability and automatic updates.

We are using OCI containers as a transport and delivery mechanism for operating system content.

Our goal is to build a community interested in minimal, secure and scalable operating systems.

Check the website for more information.
