konflux-ci/paketo

IMPORTANT: This repository has been moved to https://github.com/konflux-ci/paketo-container.git and is now ARCHIVED !

This project contains the information used by cachi2, executed part of the Konflux prefetch-dependencies task (see the prefetch-input parameter of the pipelinerun), to download the go modules needed to build the binary of the different applications.

Such applications are declared as git submodules and listed hereafter

• pack,
• jam,
• create-package,
• toml lib

The commands to build them, to move the binary within the /usr/bin folder, etc. are declared part of the Dockerfile. Such a Dockerfile is build using the konflux pipeline - see task build-container.

The RPMs which should also be installed to build the project or within the final image created top of a fedora image are listed part of the file rpms.in.yaml. The rpm urls are populated using the tool within the lock file: rpms.lock.yaml and their ubi.repo.

The image generated quay.io/redhat-user-workloads/cmoullia-tenant/paketo-container/paketo-container by konflux is pushed on the quay registry: https://quay.io/repository/redhat-user-workloads/cmoullia-tenant/paketo-container/paketo-container?tab=tags&tag=latest

You can check locally the availability of the tools by running this command:

podman run -it quay.io/redhat-user-workloads/cmoullia-tenant/paketo-container/paketo-container:<TAG> pack
podman run -it -v "$(pwd):/source:Z" quay.io/redhat-user-workloads/cmoullia-tenant/paketo-container/paketo-container:$TAG tomljson /source/builder.toml

How to guide

This section details what you should do as developer to design a project able to create an image packaging the executable that you need and that you will next use on konflux to build your own artefacts in a hermetic environment. You will then be able to replace the default buildah image with yours within the task: build-container.

To get the rpms.lock.yaml it is needed to install the following python tool: rpm-lockfile-prototype on a rhel/fedora machine:

sudo dnf install skopeo

python -m venv venv --system-site-packages
. venv/bin/activate
pip install --user https://github.com/konflux-ci/rpm-lockfile-prototype/archive/refs/heads/main.zip
git clone [email protected]:konflux-ci/paketo-container.git && cd paketo-container
rpm-lockfile-prototype rpms.in.yaml
