This OSTree training is designed to help participants understand and implement OSTree for managing immutable, versioned Linux operating system deployments. The course covers OSTree architecture, content-addressed storage, atomic upgrades, rollback mechanisms, repository management, and integration with modern Linux platforms and embedded systems. Participants will gain practical insight into building reliable, upgrade-safe, and reproducible Linux operating system environments using OSTree.

• Understand the architecture, components, and versioned filesystem capabilities of OSTree for Linux system management.
• Install, configure, and manage OSTree environments for immutable and atomic system deployments.
• Create, manage, and deploy versioned system trees, repositories, and software updates effectively.
• Implement system rollback, upgrades, branch management, and deployment automation workflows.
• Monitor, troubleshoot, and optimize OSTree-based systems for reliability, consistency, and security.
• Build scalable, secure, and production-ready immutable infrastructure solutions using OSTree best practices.
