Convert containers to bootable ISO images with BootC

In recent years, i container they have become a foundational technology in the world of software development and application management. By incorporating code, libraries, and dependencies, containers allow developers to deploy applications quickly, reliably, and consistently across different platforms and environments.

Containerization technologies have revolutionized the way applications are developed, deployed and managed, delivering advantages such as portability, isolation, lightness and scalability. With containers, professionals and businesses can reduce development time, simplify IT operations, and ensure the consistency and stability of their applications, regardless of the environment in which they run.

What is Podman Desktop in brief and how does it facilitate container management

Podman Desktop is an application that offers a graphical user interface for Podman, an open source engine for container management software. In another article we saw in detail what Podman Desktop is and how it allows users to easily manage containers on Windows, macOS and Linux platforms.

Using thegraphic interface of Podman Desktop, users can create, run, stop and manage containers directly. Cross-platform support makes it even easier to use containers with any operating system.

The idea behind Podman Desktop is to provide a lightweight and secure alternative to Docker. The platform uses the same technologies and container management tools as Podman, offering the possibility of applying a wide range of modifications and customizations.

Converting containers to images and bootable media: how to do it with BootC

A container is effectively a “container” that hosts a work environment specifically configured to work with specific operating systems and applications.

The BootC (Bootable Container) extension for Podman Desktop allows users to create bootable images starting from containers. Users, after installing BootC within Podman Desktop, they can transform the content of a container in a operating system complete, ready to be booted into a virtual machine, USB device, or as a RAW disk image.

Thanks to BootC, in short, it is possible convert a container into a complete operating system, along with the various applications, development tools and other software present.

At the moment, the extension supports Linux distributions such as CentOS, Fedora and RHEL. It allows you to use specific container files for these distributions and generate the corresponding bootable images.

Another significant advantage is that after creating a virtual machine or disk image from the container, it is possible apply updates. This means that you can, for example, update the operating system without having to create a new image.

Bootable container images created with BootC can be used on different platforms. The developers cite, for example, formats QEMU Disk Images (qcow2), Amazon Machine Images (ami), VMware vSphere (vmdk), the ability to create RAW disk images and ISO files.

The possible use cases of the BootC extension for Podman Desktop

Referring you to the GitHub repository for instructions onBootC installationthe extension for Podman Desktop finds several possible use cases.

It allows developers to create quickly and easily development environments e test isolated, where they can run and test their own applications. Furthermore, the use of bootable container images allows you to exploit already “ready to use” environments on servers, public clouds and on-premises.

Using BootC, they can be created minimized operating systems and optimized for running specific applications (or a single application…). These lightweight production environments reduce hardware requirements, improve application performance, and facilitate more efficient and scalable deployment.

What is created with BootC can be used to test and validate infrastructures and system configurations in a controlled and reproducible environment. This helps identify and resolve potential configuration issues before implementing changes into production environments.

Finally, bootable images created from containers can be leveraged for staging educational environments e di trainingwhere students can explore and experiment without worrying about damaging or compromising the production environment.
