Onboarding Guide

Onboarding Guide #

Agenda #

We have split the on-boarding process into multiple stages:

  1. Have packit tooling installed locally.
  2. RPM builds pass on your laptop.
  3. You are approved to use packit-service.
  4. The project has successful builds inside the service.
  5. Packit service handles Fedora Rawhide updates for you.

We welcome all kinds of suggestions to this guide, feel free to open a new issue here.

Have packit tooling installed locally #

In order to start using packit, we suggest you install the tooling locally. All the logic is baked inside the packit command - so once packit srpm (the command to create a source RPM locally from the current snapshot of the project) starts passing for you, it should work inside packit service as well.

Fedora Linux #

$ sudo dnf install packit

Red Hat Enterprise Linux or CentOS Stream 8 #

On RHEL/CentOS 8 you can install RPM from EPEL repository. On CentOS, some dependencies are in PowerTools repository, so you have to enable it:

$ sudo dnf install dnf-plugins-core epel-release
$ sudo dnf config-manager --set-enabled powertools
$ sudo dnf install packit

Via Fedora COPR #

You can also help us test the latest development snapshot by installing packit built from the master branch in Copr:

$ sudo dnf copr enable packit/packit-master
$ sudo dnf install packit
$ # OR in case you have packit already installed from the Fedora repositories:
$ sudo dnf upgrade packit

From PyPI #

We publish packit to PyPI and it’s available as packitos project — packit at PyPI is something different.

$ pip install --user packitos

From Source #

… or installing it directly from GitHub:

$ pip install --user git+https://github.com/packit/packit

In a container #

If none of the above work for you, try running it in a container from our Fedora based image. It contains packit installed from main branch, i.e. the same you’d get by pip installing from Github.

$ podman run -ti --rm -v $PWD:/src --security-opt label=disable quay.io/packit/packit bash
$ packit
Usage: packit [OPTIONS] COMMAND [ARGS]...

RPM builds pass on your laptop. #

Once you install packit locally, it’s time to fill .packit.yaml — the configuration file packit is using. Packit can help to fill the initial template by running the init command:

$ packit init
$ cat .packit.yaml
# See the documentation for more information:
# https://packit.dev/docs/configuration/

specfile_path: packit.dev.spec

# add or remove files that should be synced
    - packit.dev.spec
    - .packit.yaml

# name in upstream package repository/registry (e.g. in PyPI)
upstream_package_name: packit.dev
# downstream (Fedora) RPM package name
downstream_package_name: packit.dev

Head on to page configuration to learn more about the config file.

Packit supports actions and hooks: you can define your own commands which would replace packit’s implementation (e.g. get version, or create a tarball) or run specific commands after the upstream repo is cloned. Please read more about actions here: actions.

Packit needs an RPM spec file to build your package. The spec file does not need to be included in the upstream repo and can be generated on the fly or downloaded (e.g. from Fedora dist-git). Please check out our FAQ to read about some other common questions.

You can also read more about the SRPM process in the document dedicated to the srpm command.

Is your packit srpm finally passing? If not, feel free to reach out to us. If yes, let’s proceed to the next level.

Running from the dist-git repository #

When you are not allowed or do not want to run packit command from the upstream git repository, you can run commands from the cloned dist-git repository in the same way as you do from upstream. Make sure, that you specify the upstream_project_url in your configuration.

You are approved to use packit-service. #

In order to start using packit service, our GitHub app, you need to install it in your GitHub projects. Then we need to approve you (usually takes only a few hours).

The project has successful builds inside the service. #

If a SRPM can be created locally, all should be good in the service as well. That’s the theory. In practice, your laptop and packit service sandbox environment are vastly different. One thing which can happen easily is that a command is not available in the sandbox. Also, all the commands are run using an unprivileged user - you can’t install anything or perform any privileged operation. In any case, feel free to reach out to us if you are having troubles and we’d be glad to help.

In order to get RPM builds for every change in your project, you need add a section jobs inside your .packit.yaml and set up a job to do RPM builds for every change in a PR:

- job: copr_build
  trigger: pull_request
    - fedora-all

fedora-all stands for all currently available Fedora releases.

Jobs are nicely described over here.

If you are looking for an inspiration for your .packit.yaml, check packit’s config file since we try to use all the latest features.

Packit service handles Fedora Rawhide updates for you. #

So you already have a jobs section in your config. Let’s extend it with another job to push new upstream releases to Fedora rawhide.

- job: propose_downstream
  trigger: release
    dist-git-branch: master

Pretty clear I’d say: when a new upstream release happens, propose it to dist-git master branch: Fedora Rawhide. Packit enables you to decide whether you want to do a direct push or create a pull request. If you want direct pushes, you need to set a global config option create_pr to false:

create_pr: false
- job: propose_downstream
  trigger: release
    dist-git-branch: master

Packit user in Fedora is not a proven packager, so you need to grant packit user the ability to push.

Creating pull requests is easy. create_pr defaults to true so the config starting this section is good enough.
