Make debian or rpm packages out of any app, including init script, crons, logrotate, etc. Excellent way to distribute apps or command line tools without complicated installation instructions.
Hosted service available at https://packager.io/. Free for OpenSource apps.
Officially supported languages
You can also point to other buildpacks (doc). They may just work.
Supported distributions (64bits only)
- Ubuntu 14.04 ("trusty")
- Ubuntu 12.04 ("precise")
- Debian 8 ("jessie")
- Debian 7 ("wheezy")
- RHEL/CentOS 7
- RHEL/CentOS 6
- Suse Linux Enterprise Server 12
- Fedora 20
- Amazon Linux AMI 2014
See https://packager.io/ for examples of apps packaged with
pkgr (Gitlab, OpenProject, Discourse, etc.).
On a debian based build machine:
sudo apt-get update sudo apt-get install -y build-essential ruby1.9.1-full rubygems1.9.1 sudo gem install pkgr
To package your app, you can either execute
pkgr locally if your app repository is on the same machine:
pkgr package path/to/app/repo
The resulting .deb package will be in your current working directory.
Full command line options are given below:

Tools such as Capistrano are great for deploying applications, but the deployment recipe can quickly become a mess, and scaling the deployment to more than a few servers can prove to be difficult. Plus, if you're already using automation tools such as Puppet to configure your servers, you have to run two different processes to configure your infrastructure.
pkgr builds on top of the Heroku tools to provide you with an easy way to package you app as a debian package. The great advantage is that once you've built it and you tested that it
works once, you can deploy on any number of servers at any time and you're
sure that it will just work. Then, you can upgrade/downgrade or uninstall the whole application in one command.
Finally, it's a great way to share your open source software with your users and clients. Much easier than asking them to install all the dependencies manually! I'm in the process of making sure
pkgr is feature complete by trying to package as many successful open-source projects as I can. Don't hesitate to test it on your app and report your findings!
What this does
Uses Heroku buildpacks to embed all the dependencies related to your application runtime within the debian package. For a Rails app for instance, this means that
pkgrwill embed the specific ruby runtime you asked for, along with all the gems specified in your Gemfile. However, all other dependencies you may need must be specified as additional system dependencies (see Usage). This avoids the 'packaging-the-world' approach used by other tools such as omnibus (with the pros and cons that come with it), but it still allows you to use the latest and greatest libraries for your language of choice. See this blog post for more background.
Gives you a nice executable, which closely replicates the Heroku toolbelt utility. For instance, assuming you're packaging an app called
my-app, you can do the following:
my-app config:set VAR=value my-app config:get VAR my-app run [procfile process] # e.g. my-app run rake db:migrate; my-app run console; etc. my-app run [arbitrary process] # e.g. my-app run ruby -v; my-app run bundle install; etc. my-app scale web=1 worker=1 my-app logs [--tail] ...
Your app will reside in
You'll also get upstart (or sysvinit) initialization scripts that you can use directly:
service my-app start/stop/restart/status
Logs will be stored in
/var/log/app-name/, with a proper logrotate config automatically added.
Config files can be added in
You must have a Procfile.
Your application should be Heroku compatible, meaning you should be able to set your main app's configuration via environment variables.
If you're on older versions of Debian, you may need to append
/var/lib/gems/1.9.1/bin to your PATH to "see" the
If you get the following error
ERROR: While executing gem ... (ArgumentError) invalid byte sequence in US-ASCII while trying to install
pkgr, try setting a proper locale, and then retry:
sudo locale-gen en_US.UTF-8 export LANG=en_US.UTF-8 export LC_ALL=en_US.UTF-8 sudo gem install pkgr
Looking for the init script? It is created the first time you run this command
sudo my-app scale web=1 worker=1
Issue getting nokogiri to compile? Try the following based on this comment:
