How to push Fedora Badges

Architecture

The badge-awarding back-end daemon, fedbadges, wakes up when it receives a fedmsg event. It compares that message and the history in datanommer against a series of rules. If a contributor matches the criteria described in one of those rules, then they are awarded a badge.

The front-end is a web application called Tahrir. It mostly is just an interface for users to look at their badges. However, it also has an admin interface for manually adding new badges, awarding badges, and creating "invitations" (QR codes) for badges.

The badge-awarding back-end daemon, fedbadges, runs on the badges-backend01 node. The process is fedmsg-hub and logs are in /var/log/fedmsg/fedmsg-hub.log.

The front-end runs under apache/mod_wsgi on badges-web0{1,2} nodes.

Sysadmin process: How to push a Badge

Pushing badges consists of two operations:

  1. Push badge assets (.png, .svg, .yaml) to fedora-badges repository

  2. Add badge to badges.fedoraproject.org

Anyone with write permissions to fedora-badges can push badges. Pull requests can also be used. Only members of the sysadmin-badges FAS group and admins of the web interface can add badges.

Badge artists and badge developers should push design assets (png and svg art) and rules (yaml) to the fedora-badges repository.

Preparing to create a badge

Once a badge is approved by the Design Team and has the ready to push tag, they are ready to be pushed. Follow this checklist to push a new badge:

  1. Ensure artwork is approved by Design Team

  2. Ensure name and description of badge are clear

  3. Ensure one of these requirements is met:

    • Manually awarded badges: What FAS accounts receive permissions to award badge

    • Awarded via fedmsg rule: YAML file with rules is present

If you are confused or something is missing, comment on the issue and remove the ready to push tag.

Add badge assets to Pagure

  1. Download artwork and rule file (if applicable):

    • Double-check the artwork is actually the final version from ticket

    • Open / view both art files to check they are not corrupt (in the past, corrupt images were accidentally pushed)

  2. Give both art and rule files the same name, place into pngs/, svg/, rules/ directories

  3. On request only: Generate a STL file for 3D-printing a badge:

    • Change directories into bin/ and run export.sh. This creates a STL file for the badge and moves it to the correct place.

    • Check the README file in bin/ for more info about the script.

  4. Commit all files and push to fedora-badges (or make a PR)

Make sure files have a reasonable name (e.g. all-lowercase-dashes-only.png). Some types of badges follow a naming convention, like FAS group membership badges (i.e. fas-badge-name.png) or Koji build badges (i.e. koji-badge-name.png). Follow past precedent where possible. Later, the file name is used for the file on the front-end server (e.g. https://badges.fedoraproject.org/pngs/all-lowercase-dashes-only.png).

Push assets to back-end server via Ansible

Note: All assets must be in the master branch of fedora-badges before proceeding. You must also be a member of sysadmin-badges in FAS for this to work.

Next, you need to move all assets from the Pagure repository to the back-end server. This is done via an Ansible playbook from the batcave server. Follow these steps to push the assets to production.

  1. SSH into batcave01.phx2.fedoraproject.org

  2. Run the playbook: sudo rbac-playbook manual/push-badges.yml

  3. Enter FAS password and 2FA token

  4. Once finished, ensure badge is now publicly visible (i.e. https://badges.fedoraproject.org/pngs/<name>.png)

Add automatically-awarded badges

Note: Pay close attention when following these steps. It is easy to create a badge, but much harder to edit it later. Double-check information is entered correctly in the YAML file on first go, or else you have to write SQL statements to fix it later.

Automatically awarded badges are created by the YAML rule file. Once the Ansible playbook finishes, the badge is created and placed in the badges index. The only part not created automatically are tags (see Badge metadata below for info about tags). To add new tags, find the badge on badges.fedoraproject.org. If you are logged in as an admin, there is a text field to enter in new tags.

Add manually-awarded badges

Note: Pay close attention when following these steps. It is easy to create a badge, but much harder to edit it later. Double-check information is entered correctly on first go, or else you have to write SQL statements to fix it later.

Once the badge assets are pushed to the back-end, add the badge to the front-end, Tahrir. The front-end is hosted at badges.fedoraproject.org. Follow these steps to add the badge in Tahrir.

  1. Open Admin interface on badges.fedoraproject.org

  2. Go to the Add badge section.

  3. Enter in all information as provided in the badge ticket (see Badge metadata below.)

  4. Double-check all entered information is correct and accurate

  5. Click Create badge to create new badge

The badge is now created. You should be able to find in the badges index.

Grant authorizations

Manually-awarded badges require authorized users to issue a badge. You can do this at the bottom of the Admin interface, near Create Authorizations. Add the person to receive awarding privileges into the Person Email field. This must be formatted as their fedoraproject.org email address (e.g. FASuser [at] fedoraproject [dot] org). For badge name, use the slug (or badge name) from the URL of the badge (e.g. for badges.fedoraproject.org/badge/commops-superstar, this is commops-superstar).

To add multiple users, repeat this process for each user.

Badge metadata

  • Name: name of the badge – this determines URL of badge, so triple-check for typos

  • Image: full link to the PNG (e.g. https://badges.fedoraproject.org/pngs/all-lowercase-dashes-only.png)

  • Description: badge description text (ensure there is no hanging whitespace)

  • Criteria: link to the issue in fedora-badges

  • Issuer: keep the default

  • Tags: comma-delimited list of tags:

    • Review other similar badges to ensure tags are correct. Some tags are special and function as categories.

    • Follow past precedent for tags. Avoid creating new tags if at all possible.

    • Removing tags is not easy. Adding them later is easy.

Close out the ticket

After pushing the badge, do some last checks to make sure the badge pushed correctly. Make sure the page is viewable and double-check that it is categorized correctly in the badges index.

Return to the Pagure issue for the badge. Post a link to the pushed badge. If you granted authorizations, list the FAS usernames you granted authorizations to. After commenting, closing the issue as pushed.

Congratulations, you just pushed your very own Fedora Badge!

How to manually award a badge

To perform this, you must be in the sysadmin-badges FAS group.

There is a script installed on badges-backend01 in /usr/local/bin/award-badge. It has help options that you can pull up with award-badge -h. It takes a required --user FAS_USERNAME and a required --badge BADGE_ID option. For example, the following invocation would award the "Associate Editor" badge to "ralph":

sudo /usr/local/bin/award-badge --user ralph --badge associate-editor

The BADGE_ID for a badge can be found by visiting its page on the web UI. That badge can be found at https://badges.fedoraproject.org/badge/associate-editor.

The award-badge script and source code is managed by ansible.git. The source code is in roles/badges/backend/files/award-badge.

Often enough, there is need for a workflow to batch award a badge to a number of people. For instance, the Keepin' Fedora Beautiful badge comes from a member of the Design Team posting a ticket with a list of FAS usernames (i.e. fedora-badges#129).

For cases, like that you can wget the file with the list of FAS usernames on badges-backend01 and run something like:

$ for i in $(cat keepingbeautiful-list ) ; do
    sudo /usr/local/bin/award-badge --user $i --badge keepin-fedora-beautiful-f20;
done

How to manually revoke a badge or authorization

You may revoke badge or badge authorizations in a similar fashion to the award-badges script. You may chain the invocation of the revoke-badge or revoke-authorization script in the same manner as the award-badges script.

Revoking a badge:
sudo /usr/local/bin/revoke-badge --user ralph --badge associate-editor
Revoking an authorization:
sudo /usr/local/bin/revoke-authorization --user ralph --badge associate-editor

How to add admins to Tahrir

It would be nice if we could automatically grant admin access in the web interface to members of the sysadmin-badges FAS group. We currently do not have this feature and must maintain the list of web UI admins separately.

The configuration file for the badges front-end web app is managed by ansible.git. The source code is in roles/badges/frontend/templates/tahrir.ini.

In that file, find the tahrir.admin option. It is a comma-separated list of email addresses that, when logged in, should be granted rights to access the admin panels at badges.fedoraproject.org.

To add a new admin, add their FAS_USERNAME@fedoraproject.org email to that line, commit, and push. Use Ansible to run the groups/badges-web.yml playbook to push the config change out to the web front-end nodes.

How to create an invitation and QR code

This is done through the admin panel of the web interface (although we can probably write a script for it to be used on the back-end node).

Invitations / QR codes are typically created for Fedora events. For instance at the Flock 2013 Fedora Contributors conference, we created a badge to award attendees. We followed the procedure below to generate an invitation and a QR code. Next, the QR code was distributed to conference organizers. They added the QR code to the program brochure that each attendee was given. Then, any attendee that scanned the code was redirected on their phone to the badges app, where they were awarded the badge.

Create an invitation

  1. Make sure you are an admin in the web interface and logged into badges.fedoraproject.org

  2. Click the Admin link in the UI

  3. Under the Invitations section, add this information:

    • Creation Date: Optional. It defaults to the current date.

    • Expiration Date: Optional, but you probably want to specify one. It defaults to 2 hours from the current time. For instance, at the Flock 2013 conference, we set the expiration date at the end of the conference. Anyone who tried to claim the badge with the QR code after that time would be denied, with the message this invitation is expired.

    • Badge ID: "ID" of the badge you want to award. See the section above for how to find a badge ID.

    • Person email: Email of a person in the badges database. In our case, use their Fedora email (e.g. FAS_USERNAME@fedoraproject.org).

Now, the user you specified will have a link to the QR code and invite link on their profile page. They can take initiative to distribute and share the badge as they wish.

Useful scripts for manual work

See ansible/roles/badges/backend/files/ for the motherload. These all get deployed to /usr/local/bin/ on badges-backend01 where you can login to execute them.

edit-badge

Update the description and the criteria link for a badge. Useful in the event you created it incorrectly, or if feedback from other stakeholders requires us to change something.

award-badge

Award a badge to a specific user.

revoke-badge

Removes a badge from a user to whom it has been awarded erroneously. Remember! If you revoke a badge award from a user, you should also give them the consolation-prize badge as a token of apology.

grant-authorization

Grant authorization rights on a badge to a privileged user. They can then create invitation links and QR codes for that badge as well as award it directly to other users from the web interface.

revoke-authorization

Revoke those authorization rights for a user on a given badge.
