Fedora Toolbx images
====================

This document contains information about current workflow used to build and publish Toolbox images.
It also describes changes needed to make it work with `quay.io <https://quay.io>`_.

Current workflow
----------------

The toolbx images are currently built using OSBS. The OSBS submits builds to
`candidate-registry.fedoraproject.org <https://candidate-registry.fedoraproject.org/>`_ using
dockercfg and user can create an update in Bodhi. After testing period is finished or the update
gets enough karma it is moved by bodhi to
`registry.fedoraproject_org <https://registry.fedoraproject.org/>`_.

This will change in F39 where the images will be built by
`koji-flatpak <https://pagure.io/koji-flatpak>`_ plugin. This plugin will submit the builds to
both `registry.fedoraproject_org <https://registry.fedoraproject.org/>`_ and
`quay.io <https://quay.io>`_.

Changes for quay.io
-------------------

This section will describe changes that are needed to make quay.io work with current setup.
It will go through pipeline step by step and describe what needs to be changed in case of
toolbx workflow.

OSBS
^^^^
OSBS is using Openshift local container registry, which is configured by
`dockercfg <https://pagure.io/fedora-infra/ansible/blob/main/f/files/osbs/dockercfg-production-secret.j2>`_
file and pointing to candidate-registry. There is dockercfg for
`production <https://pagure.io/fedora-infra/ansible/blob/main/f/files/osbs/dockercfg-production-secret.j2>`_ and `staging <https://pagure.io/fedora-infra/ansible/blob/main/f/files/osbs/dockercfg-staging-secret.j2>`_.
This dockercfg is used as a secret in OSBS and it's deployed in
`setup-worker-namespace <https://pagure.io/fedora-infra/ansible/blob/main/f/playbooks/groups/osbs/setup-worker-namespace.yml>`_ playbook.
To make this work with quay.io we need to replace the dockercfg with new one pointing to quay.io.

.. note::

   OSBS could have trouble reaching to quay.io, this needs to be solved for this to work.

Koji
^^^^
There is currently a initiative that is trying to remove OSBS from flatpak build pipeline. At
the time of writing this document this is only enabled for F39. But as the F38 flaptak runtime
will be considered EOL the `koji-flatpak <https://pagure.io/koji-flatpak>`_ module will be the only
way.

The koji-flatpak module is much direct, there is just one
`configuration file <https://pagure.io/fedora-infra/ansible/blob/main/f/roles/koji_builder/templates/flatpak.conf>`_
used to specify where the koji builders should push the build container. The `candidate-registry`
variable is set in `tasks/main`.

Currently the builders don't have access to quay.io. The firewall settings needs to be adjusted
so they could push containers.

Bodhi
^^^^^

Bodhi is pushing the container builds from candidate-registry.fedoraproject.org to
registry.fedoraproject.org and this is configured in
`production.ini template <https://pagure.io/fedora-infra/ansible/blob/main/f/roles/bodhi2/base/templates/production.ini.j2>`_
in ansible.

To make it work with quay.io we just need to change `container.destination_registry` and
`container.source_registry` variables.

.. note::

   Bodhi wouldn't be part of the toolbx workflow in Fedora 39 and later. So no need to change
   anything here.

Toolbx
^^^^^^

Toolbx has the `registry.fedoraproject_org <https://registry.fedoraproject.org/>`_ set in code.
This needs to be changed before we completely switch to `quay.io <https://quay.io>`_.
