FUEL

This git repository contains Fuel ISO build scripts.

Directory structure:

• bootstrap Scripts for building CentOS based bootstrap ramdisk. The Fuel discovery agent (nailgun-agent) and Fuel operating system provisioning agent (fuel-agent) are installed into this ramdisk.
• docker Scripts for building Docker containers are located. The Fuel master node is deployed using Docker. Every Fuel major component like Nailgun, Astute, Cobbler, Mcollective, etc. is installed as a separate Docker container.
• fuel-bootstrap-image Scripts which allow us to build Ubuntu based bootstrap ramdisk on the Fuel master node in runtime. The status of this ramdisk is experimental.
• image Scripts to build CentOS based target operating system image. We install this image on the Fuel slave nodes. This image being installed on a node provides fully functional standalone operating system. (being deprecated)
• iso Scripts that are used for building Fuel ISO.
• mirror Scripts to build local mirrors that are used for building chroot environments, bootstrap and target images, etc.
• packages Scripts that are used for building Fuel RPM and DEB packages.
• specs RPM spec for fuel and fuel-release packages.
• utils Auxiliary scripts. (being deprecated)
• virtualbox Scripts that allow a user to try Fuel easily. Being run they start several virtual box VMs. One of them is used for the Fuel master node and others are used as slave nodes where Fuel installs an operating system and deploys OpenStack.
• Makefile It is the main GNU Make file which includes all other necessary GNU Make files.
• config.mk The file where the whole build process is parametrized.
• prepare-build-env.sh The script installs all necessary packages that are needed for the build process. Currently only Ubuntu 14.04 is supported.
• repos.mk The script which downloads git repositories that are needed for the build process.
• requirements-rpm.txt This file is used when building local RPM mirror. All RPM packages that are needed for Fuel are listed here.
• sandbox.mk The script that is used for building chroot environments.
• virtualbox.mk The script that is used for preparing tarball archive with virtualbox scripts.
