fedflare

Python-based CLI app for cache invalidation and warm up for a Cloudflare mirror of Fedora repositories.

The fedflare CLI program:

• invalidates changed repomd.xml files, ensuring that Cloudflare mirror is always fresh
• warms up Cloudflare's repomd.xml copy (currently limited feature, because it warms up from a single location only)

Use epel.cloud

Install epel-release with CDN base URLs in lieu of standard releases packages.

CentOS/RHEL 7

sudo yum -y install https://epel.cloud/pub/epel/epel-release-latest-7.noarch.rpm

CentOS/RHEL 8

sudo dnf -y install https://epel.cloud/pub/epel/epel-release-latest-8.noarch.rpm

fedflare at its core

fedflare is what makes this simple yet fast CDN possible. It ensures that the Cloudflare CDN is in sync with actual Fedora repositories.

How this works

This script requests every repo's repomd.xml from Fedora servers, and then caches it locally. Changes in cache state for a repomd.xml will mean that the repomd.xml needs to be invalidated.

As such, we have a highly-cacheable CDN of Fedora repositories, hosted on Cloudflare, with virtually no stale data whatsoever.

Running

fedflare domain.com

By default, it will work (and currently only supports) EPEL repositories by Fedora.

Live implementation can be found, and is much recommended for use: epel.cloud.

Example installation

First, git clone the project to home directory of a user, and set up Python 3.6 virtual environment in venv subdirectory of the cloned repository, and run pip install -r requirements.txt.

Then, replace <username> with your username in the following commands and configs.

cp /home/<username>/fedflare/fedflare.service /etc/systemd/system/fedflare.service
systemctl daemon-reload
systemctl enable --now fedflare
systemctl status fedflare
