How image mode changes system management

When containers first arrived, many sysadmins had to rethink everything they knew about managing Linux systems. Instead of making changes directly, you defined them in a container file, pushed them to a registry, and pulled them into production. Image mode applies that same approach to servers. In this episode, we break down how image mode works, what makes it different from virtual machines, and why its immutable file system design creates more reliable Linux environments. We also cover where configurations and variable data live, and the key practices to keep in mind when running image mode in production.
