EL AtomicOS 10

Enterprise Linux Atomic Operating System for RHEL 10 and all compatible distributions.

EL AtomicOS 10 is an immutable, container-focused operating system designed for modern cloud, edge, and enterprise workloads. It features:

• Atomic, transactional updates using OSTree and rpm-ostree
• Full compatibility with RHEL 10, AlmaLinux 10, Rocky Linux 10, Oracle Linux 10, CentOS Stream 10, and other Enterprise Linux 10 derivatives
• Out-of-the-box support for Podman, Docker, and Kubernetes workloads
• Web-based management via Cockpit (with Podman, Docker, and Kubernetes modules)
• Secure defaults with SELinux enforcing
• Persistent journald logging and robust systemd service management
• Minimal, cloud-ready, and edge-optimized footprint

Key Features

• Immutable base system with atomic updates and rollback
• Container-first design: Podman, Docker, and Kubernetes supported side-by-side
• Web management: Cockpit with Podman, Docker, and Kubernetes integration
• Kubernetes node/cluster support (kubelet, kubeadm, kubectl included)
• Docker CLI, daemon, Compose, and Buildx support
• Enhanced security: SELinux enforcing, minimal attack surface
• Automated installation and configuration via Kickstart
• Fedora CoreOS-style partitioning (no LVM, XFS root, ext4 /boot, EFI, swap)

Documentation

• Installation and User Manual
• Kickstart Example
• Project Wiki

Quick Start

1. Download the Kickstart file and boot your system with the appropriate installation media.
2. Use the Cockpit web interface at https://<hostname>:9090 for system and container management.
3. Manage containers with Podman, Docker, or Kubernetes from the CLI or Cockpit.

Security Notes

• Default user: atomic (password: atomic) — change immediately after install
• SELinux is enforcing by default
• Cockpit and container ports are open in the firewall for remote management
