Metrics : fedmsg plugin for perceval


During the course of the project, you will be closely working with the Fedora Community Operations (CommOps) Team to build a metrics dashboard for the community. For building the dashboard, we will be using Grimoirelab suite of tools to build the backend as well as the frontend.

Perceval is a tool that collects data from a given data source and has a lot of pre-defined plugins. The aim of this project is to add fedmsg support to it so that metrics can be pulled out of it, suitable for the Fedora community.

Final Deliverables

Primary Objectives:

  • A working fedmsg consumer

  • A plugin for perceval to pull metrics from fedmsg directly

  • Documentation for the plugin

Secondary Objectives: - Additional plugins to support Wordpress, Twitter and other data sources

Pagure: A git based source repository

  • Difficulty: Intermediate

  • Technology: Python, git, pygit2

  • Mentors: pingou

Applicants interested in Pagure must contribute by solving easy fix issues before the end of the application period.

Pagure is a git-centered forge, python based using pygit2.

With pagure you can host your project with its documentation, let your users report issues or request enhancements using the ticketing system and build yourcommunity of contributors by allowing them to fork your projects and contributeto it via the now-popular pull-request mechanism.

Projects in Pagure will be selected by the student in concert with the mentor. They will be drawn from the non-easyfix issues in the issue queue. Students are expected to guide the mentor in helping them select areas of interest.

Fedora Packets: Fedora Happiness Packets


Add Fedora user account authentication and fedmsg integration to Happiness Packets to deploy in Fedora’s infrastructure


Happiness Packets is a web application to send positive feedback and thank-you notes to open source contributors. You can send a note with your name or anonymously. The Fedora community plans to have a Fedora Appreciation Week in 2018, where contributors thank each other and celebrate our accomplishments together. Fedora wants to extend Happiness Packets by giving a Fedora Badge to anyone who sends a Happiness Packet to another contributor. To do this, we need to fork Happiness Packets and add support for Fedora’s authentication system and add a fedmsg hook. This lets Fedora contributors log in and receive a badge when they send a Happiness Packet.


The project is split into primary deliverables (required) and secondary deliverables (optional).

Primary deliverables
  • Add back-end support for Ipsilon authentication

    • Push the application upstream

  • Integrate fedmsg publishing

  • Create Fedora Badge rule file to automatically award badge

Secondary deliverables
  • Add support for video messages

  • Add support for emojis

  • Explore major social media APIs (for example, Twitter, Facebook, Reddit) to allow sharing on social networks

    • Twitter

    • Facebook

Atomic IoT (likely useful in numerous other Atomic ideas) host upgrade daemon

  • Skill level: medium

  • Skills required: python3 ans/or C

  • Mentor(s): Peter Robinson

IoT devices need to be almost impossible to brick. When you upgrade a device if it doesn’t work it needs to be able to automatically role back, or at the very least be able to contact the update service for a newer fixed version.

A daemon to manage this state is required. The daemon would need to be able to do the following:

  • Monitor the status of available downloads

  • Apply the Atomic update delta

  • Set a "boot once" flag to boot the new version via grub

  • Set a hardware watchdog

  • initiate a reboot of the system

  • If boot to normal userspace fails the watchdog triggers and it resets to the old version

  • If boot succeeds to the point the daemon starts up it then proceeds to phase two of the upgrade process

  • Unsets watchdog so the OS won’t reset

  • Checks it can see all required network interfaces

  • Checks it can resolve addresses and contact the update server

  • Check it’s connected to all other critical services (eg MQTT or a HTTPS API

  • Checks it can see and all sensors and services are running correctly

There needs to be a means of specifying what components are critical to the successful operation of the device. Some components will be the same across all types of device such as the ability to check network interfaces are operating, to check an update service is available, to check services are available etc but some might be plugins eg to check GPIO is working, specific IIO sensors, cameras or other such things are seen as expected.

  • What are we looking for: An initial daemon with basic functionality with good design that can be extended. Integration with atomic updates etc.

Fedora Dockerfile linter leveraging Container Best Practices

  • Skill level: Intermediate

  • Skills required: Python, containers

  • Mentor(s): Tomas Tomecek, Eliska Slobodova

  • Contacts (IRC & email): ttomecek (ttomecek, eslobodo (eslobodo


Fedora infrastructure for container image delivery is lacking any kind of automated testing of the images or underlying Dockerfiles. The Container Best Practices document is a digest of recommended practices for writing and deploying images.


With Container Best Practices serving as a “cheatsheet”, you will create a tool to perform basic and advanced checks on Dockerfiles and images that can be applicable generally regardless of an image. In cooperation with the Fedora infrastructure team, you will deploy the tool in the container infrastructure so that the tests can be executed automatically upon a new build/commit or locally before the developer pushes the changes remotely.

Advanced test cases for images running in OpenShift using conu

  • Skill level: Intermediate

  • Skills required: Python, containers, OpenShift

  • Mentor(s): Tomas Tomecek, Dominika Hodovska

  • Contacts (IRC & email): ttomecek (ttomecek, dhodovsk (dhodovsk


Conu is a library which provides Python API to interact with a selected container runtime. It simplifies writing of tests for container images. However, the project currently lacks support for OpenShift and Kubernetes.


  • Your primary goal will be to deliver at least 10 new functions that will enable the users to write tests for OpenShift scenarios.

  • Your secondary goal will be to write test for at least 5 images (eg mariadb, mysql, postgresql, golang, rust) using conu’s full capabilities.

Complete support for OpenShift and Kubernetes as a backend in conu

  • Skill level: Intermediate - Expert

  • Skills required: python, containers

  • Mentor(s): Tomas Tomecek

  • Contacts (IRC & email): ttomecek (ttomecek


conu defines a generic API to interact with containers and container engines. To make the project more usable, we would like to add implementation of well known container orchestration systems — Kubernetes and OpenShift.


  • Write a series of pull requests to add support for Kubernetes and OpenShift in conu project.

  • The newly added functionality needs to have integration tests which can run inside CI environment and are passing.

  • And finally, the feature should be demonstrated it works well by at least 3 real examples.

Continuous Integration for Fedora Media Writer + Tests

  • Skill level: Intermediate

  • Skills required: CI, C++, Qt

  • Mentor(s): Martin Bříza

  • Contacts (IRC & email): mbriza@freenode &


Fedora Media Writer is a tool with two build platforms and three deployment platforms. It’s quite challenging to check all the new added code for being able to build properly and as of now, there are no tests.

Your task in this project would be to get a CI platform of your choice to work well with FMW on GitHub. The required environments are Fedora and macOS. Windows builds are done using the MinGW packages in Fedora and FMW can run using Wine - this should be sufficient for testing, however testing the MinGW builds under native Windows is a definite plus.

Qt provides the QTest framework for testing the application - it’s the preferred platform to write tests in this case, however using a bash or Python library is likely okay, too. However, once again, as QTest is easily attachable to the internal structures of FMW, it’s strongly suggested.

Bonus points are if you get automatic binary builds published in the Releases section for tags.


Working CI integration for macOS and Fedora-latest or Rawhide. A set of tests covering at least 5 closed bugs.

ARM uBoot Support in Fedora Media Writer

  • Skill level: Intermediate - Expert

  • Skills required: C++, Qt, ext4, bash/Python (?)

  • Mentor(s): Martin Bříza

  • Contacts (IRC & email): mbriza@freenode &


Fedora Media Writer now supports writing ARM images to portable media. These cards can then boot on devices that support Fedora out of the box, like the Raspberry Pi. However, to support most other boards, one has to do some modifications to the image on the flash drive. The first of them is writing uBoot (open source bootloader) to the start of the drive. Then it’s sometimes necessary to tweak some environment variables or modify a configuration file.

These are the tasks that are possible to be automated. However, it’s necessary to find a way how to do that in a clean fashion. As an example of an approach to this problem, you can take a look at the arm-image-installer. One option would be to cooperate with the ARM SIG to create a solution that uses their know-how or code directly. I have some ideas so please go ahead and talk to me.

Remember, this is pretty trivial to do on Linux, however we need this functionality to work on Windows and macOS. This induces issues - especially with filesystem handling. For your project proposal, I expect you include a rough description of how you’re planning to tackle this problem.


A Fedora Media Writer build that’s able to deliver a Fedora SD card that can boot on a currently unsupported ARM platform (for example, Cubieboard) on Linux, Windows and macOS.
