dnf install docker docker-compose podman
/usr/sbin/usermod -a -G docker sergiomb
cat /etc/group | grep sergiomb
systemctl start docker

user:
 git clone https://pagure.io/copr/copr.git
 cd copr/
 docker-compose up -d


after we need init database and add create the chroots
docker exec -it copr_frontend_1  bash
cat /usr/bin/init-database.sh
#!/bin/bash

cd /usr/share/copr/coprs_frontend/ && copr-frontend create-db --alembic alembic.ini
copr-frontend create-chroot
$(ls /etc/mock/{fedora--{i386,x86_64}.cfg,epel--x86_64.cfg} |xargs -I{} -n1 basename {} .cfg)

and the problems start here
the components of corp use corp rpms on https://copr.fedorainfracloud.org/coprs/g/copr/copr/ and not the git source , so the fix on git aren't there

@copr/copr Copr

and we need this commit https://pagure.io/copr/copr/c/15726fc653461d8e0309602b70c4ad23984c0fff?branch=main to builder sign the packages (this one is docker configuration should be transparent)

copr-frontend create-chroot also have issues that I solved manually directly on database , after talk with copr guys , and is running smooth
