GitHub - chuyd/linuxbuilder: Create a Linux image based on multiple OS flavors (Centos,ClearLinux,Fedora,LFS)

Linuxbuilder helps you to create a Linux image based on multiple OS flavors (Centos,ClearLinux,Fedora,LFS,debian). This project is intented for anyone that wants to build a Linux Image (img/iso/kvm/cloud) based on RPMs and DEBs.

We create this project to avoid the nightmare of create your own tools/scripts for the creation of your customized distribution, this project provide the tools to do that with a simple command line (Make).

Inputs

The input are either:

  • remote_repository.conf: Point where the tool will consume all the necessary RPMs/DEBs needed to generate a basic image

  • ister_image.conf: Index of partitions for the image

  • packages_list.conf : List of packages and versions (if not specified it will take the latest from repository) to install in the image

  • localrepo/ : repo data with local deb/rpms

Output

  • linux.img : Image with everything installed and ready to just create a user and password
  • linux.iso file : Image to install on VMs or baremetal systems

Prerequisites

At least have the following development bundles and packages installed

Or use the following container:

How to build an standard image

  • Ubuntu base image:
    $ make image OS_KIND=ubuntu
    $ ls image_ubuntu.iso
    $ ls image_ubuntu.img
  • Centos base image:
    $ make image OS_KIND=centos
    $ ls image_centos.iso
    $ ls image_centos.img
  • CLR base image:
    $ make image OS_KIND=clr
    $ ls image_clr.iso
    $ ls image_clr.img

How to build a package

Imagine that you have the following repository:

libvirt/
├── deb_base
│   └── ubuntu
│       ├── patches
│       │   └── cve_fix.patch
│       └── rules
└── rpm_base
    ├── centos
    │   ├── cve_fix.patch
    │   ├── improve_perf.patch
    │   └── libvrit.spec
    ├── clr
    │   └── cve_fix.patch
    └── fedora
        └── cve_fix.patch

The developer needs to copy the src/Makefile.pkg as Makefile in libvirt/rpm_base/centos:

    $ cp src/Makefile.pkg pkgs/libvirt/rpm_base/centos
    $ cd pkgs/libvirt/rpm_base/centos
    $ make OS_KIND=centos

This will generate a RPMs under:

    libvirt/rpm_base/centos/rpms 

and log files under:

    libvirt/rpm_base/centos/logs

Same thing for debian base, developer can just run

    $ cd libvirt/rpm_base/ubuntu
    $ make OS_KIND=ubuntu

This will generate DEBs under:

    libvirt/deb_base/ubuntu/debs

and log files under:

    libvirt/deb_base/ubuntu/logs

How to build a custome image:

Lets take the example of a Centos base image that we create before and libvirt:

    $ cd pkgs/libvirt/rpm_base/centos
    $ make repoadd REPO_PATH=~/repo <if not specified it will use ./repo>
    $ cat packages_list.conf | grep <libvirt> (make sure that your package is
    on the list , the tool will install the runtime dependencies)
    $ make image OS_KIND=centos REPO_PATH=~/repo <if not specified it will use
    ./repo>
    $ ls image_clr.iso
    $ ls image_clr.img
