Building DreamOS Images via Podman

Container on Modern Linux Distributions

ubuntu/debian

==================================================

Podman Container :

An open-source tool for managing containers without the need for a background service (daemon), considered a safer and lighter-weight alternative to Docker. It allows us to:

• Build Container Images
• Run containers with complete isolation
• Manage networking and Volumes
• Run without root privileges (rootless mode) → Higher security.

In the Script :

Podman is used for:

• Isolating the build environment: (OpenEmbedded + BitBake + Git) within a dedicated container.
• Compatibility with modern distributions: (e.g., Ubuntu 24.04/25.10) without conflict — because the base environment (Ubuntu 16.04/18.04) is internally emulated/simulated via the image.
• Repeatability and portability: Build the image once → run it on any system that supports Podman.
• Secure integration with SSH: By binding the SSH_AUTH_SOCK inside the container — without manually copying keys.

Compatible Linux Distributions :

The script is designed to run on Linux distributions based on (Ubuntu/Debian) such as:

ubuntu - zorin os - deepin - linux mint - AnduinOS - Pop!_OS - MX linux

Lubuntu - Elementary OS - Ubuntu Budgie - Kali Linux - Ubuntu Unity.....etc

Workflow / Steps :

• A GitHub account is available / required
• Download the opendreambox.sh script from the attachments
• Execute the script using the following commands in the Terminal:

chmod +x opendreambox.sh
./opendreambox.sh

• The build folder is located at the path: home/opendreambox-krogoth or home/opendreambox-pyro

• After completion, you will find the image at the path: home/opendreambox-xxxx/build/dmxxx/tmp-glibc/deploy/images/dmxxx

• To directly access the device image build (after building the container image) via the terminal, use : krogoth-build or pyro-build

• To access the build folder via the terminal, use: pyro-shell or ( the equivalent for krogoth-shell)
