Capistrano::Procfile

This gem helps exporting [Procfile][https://devcenter.heroku.com/articles/procfile] to system init daemon (e.g. systemd, upstart) configurations.

Notice: This gem calls foreman export to do the things. Therefore the supported format by foreman should be supported as well. However I use only systemd, so others formats are not tested. PRs are welcome! :)

Currently we supports systemd only.

Add this line to your application's Gemfile:

gem 'capistrano-procfile'

And then execute:

$ bundle

Or install it yourself as:

$ gem install capistrano-procfile

The following options are available. You can set these options in config/deploy.rb.

set :procfile_roles, %w(app)
set :procfile_use_sudo, false
set :procfile_options, {
	export_format: :systemd,
	export_path: "/etc/systemd/system",
	working_dir: release_path,
	log_dir: File.join(release_path, "log"),
	base_port: 5000,
	app_name: fetch(:application),
	user: nil,
	formation: "all=1"
}

Run cap production procfile:export to export on the target machine.

Host property is also available for options. Check the following example.

# config/deploy/production.rb

server 'production1', user: 'app', roles: %w{app}, procfile_options: { formation: "web=1,worker=1" }
server 'production2', user: 'app', roles: %w{app}, procfile_options: { formation: "worker=4" }

After checking out the repo, run bin/setup to install dependencies. Then, run rake false to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
