|
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](./references/) 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.
|
|
|
|
```
|
|
# Syncs all repositoryes for the "9" release
|
|
% poetry run sync_from_peridot --release 9 --clean-old-packages
|
|
|
|
# Syncs only the BaseOS repository without syncing sources
|
|
% poetry run sync_from_peridot --release 9 --clean-old-packages --repo BaseOS --ignore-source
|
|
|
|
# Syncs only AppStream for ppc64le
|
|
% poetry run sync_from_peridot --release 9 --clean-old-packages --repo AppStream --arch ppc64le
|
|
```
