Empanadas

This page goes over empanadas, which is part of the SIG/Core toolkit. Empanadas assists SIG/Core is composing repositories, creating ISO's, creating images, and various other activities in Rocky Linux. It is also used for general testing and debugging of repositories and its metadata.

General Information

empanadas is a python project using poetry, containing various built-in modules with the goal to try to emulate the Fedora Project's pungi to an extent. While it is not perfect, it achieves the very basic goals of creating repositories, images and ISO's for consumption by the end user. It also has interactions with peridot, the build system used by the RESF to build the Rocky Linux distribution.

For performing syncs, it relies on the use of podman to perform syncing in a parallel fashion. This was done because it is not possible to run multiple dnf transactions at once on a single system and looping one repository at a time is not sustainable (nor fast).

Requirements

  • Poetry must be installed on the system
  • Podman must be installed on the system
  • fpart must be installed on the system (available in EPEL on EL systems)
  • Enough storage should be available if repositories are being synced
  • mock must be installed if building live images
  • System must be an Enterprise Linux system or Fedora with the %rhel macro set

Features

As of this writing, empanadas has the following abilities:

  • Repository syncing via dnf from a peridot instance or applicable repos
  • Per profile dnf repoclosure checking for all applicable repos
  • Per profile dnf repoclosure checking for peridot instance repositories
  • Basic ISO Building via lorax
  • Extra ISO Building via xorriso for DVD and minimal images
  • Live ISO Building using livemedia-creator and mock
  • Anaconda treeinfo builder
  • Cloud Image builder

Installing Empanadas

The below is how to install empanadas from the development branch on a Fedora system.

% dnf install git podman fpart poetry mock -y
% git clone https://git.resf.org/sig_core/toolkit.git -b devel
% cd toolkit/iso/empanadas
% poetry install

Configuring Empanadas

Depending on how you are using empanadas will depend on how your configurations will be setup.

  • empanadas/common.py
  • empanadas/config/*.yaml
  • empanadas/sig/*.yaml

These configuration files are delicate and can control a wide variety of the moving parts of empanadas. As these configurations are fairly massive, we recommend checking the reference guides for deeper details into configuring for base distribution or "SIG" content.

Using Empanadas

The most common way to use empanadas is to sync repositories from a peridot instance. This is performed upon each release or on each set of updates as they come from upstream. Below lists how to use empanadas, as well as the common options.

Note that for each of these commands, it is fully expected you are running poetry run in the root of empanadas.
