RHEL 9 and PyPI RPMs
My colleague, @FrostyX, recently shared a Red Hat Developer article, Thousands of PyPI and RubyGems RPMs now available for RHEL 9, with us.
TL;DR access thousands of RPMs automatically generated from PyPI and RubyGems on RHEL 9.
Sounds intriguing, I wanted to give it a shot.
Task
Build our python library ogr with those RPMs.
Do
Let’s launch a UBI9 container:
$ podman run --rm -ti registry.access.redhat.com/ubi9/ubi bash

Well, hello!
Let’s enable the Copr project with the PyPI RPMs:
[root@56cfdd79ba1e /]# dnf copr enable @copr/PyPI epel-9-x86_64

Neat.
Ogr doesn’t need anything from EPEL, so we should be good here.
Create SRPM
On my host system, I’ll create an SRPM from upstream ogr repo using Packit.
$ cd ogr
$ packit srpm
...
2022-06-14 08:47:27.188 srpm.py INFO SRPM: /home/tt/g/packit/ogr/python-ogr-0.34.1.dev82+g83ca4c8-1.20220614084726571994.main.82.g83ca4c8.fc36.src.rpm
We can now copy it inside the UBI9 container:
$ podman cp ./python-ogr-0.34.1.dev82+g83ca4c8-1.20220614084726571994.main.82.g83ca4c8.fc36.src.rpm crazy_beaver:/root
Create RPM
Back to the container env. We need rpmbuild program so we can build binary RPMs:
[root@56cfdd79ba1e /]# dnf install -y rpm-build
...
Installed:
...
rpm-build-4.16.1.3-12.el9_0.x86_64
Complete!
And we also need build dependencies for ogr. This is the time where the repo will shine:
[root@56cfdd79ba1e /]# cd /root
[root@56cfdd79ba1e ~]# dnf builddep -y ./python-ogr-0.34.1.dev82+g83ca4c8-1.20220614084726571994.main.82.g83ca4c8.fc36.src.rpm
