Prepper

Prepper is a simple server provisioning tool, built on top of SSHKit. You can use it to script your server build process. It is heavily inspired by (Sprinkle)[https://github.com/sprinkle-tool/sprinkle], but Sprinkle doesn't seem to be maintained anymore, that's why Prepper was born.

Installation

$ gem install prepper

Usage

Prepper works with "packages". You define a package with a name and pass it a block. Within that block you can execute commands on the target host. There are built in helpers to install apt packages, manage directories and upload files to the server, etc.

A simple example:

server_host "YOUR_SERVER_IP"
server_port 22
server_user "root"

# let's install the necessary packages to run a Rails app with Postgresql
package :apt do
  apt_update
  apt_install %w(git-core build-essential libcurl4 libcurl4-openssl-dev libjemalloc-dev postgresql-client libpq-dev postgresql-contrib)
end

# now we will add a deploy user
package :add_deploy_user do
  add_user 'deploy', shell: '/bin/bash', flags: '--disabled-password'

  directory '/home/deploy/.ssh', owner: 'deploy:deploy'
  file '/home/deploy/.ssh/authorized_keys', owner: 'deploy:deploy', mode: '655', content: 'ssh-rsa YOUR PUBLIC SSH KEY'
  file '/etc/sudoers.d/deploy', owner: 'root:root', template: 'sudoers'
end

# install rbenv and Ruby 3.1.2
package :install_ruby do
  install_rbenv 'deploy'
  install_ruby 'deploy', '3.1.2', '--with-jemalloc'
end

You can see a full example in examples/config.rb. You would run that file with bundle exec prepper config.rb to provision the server.

The API documentation can be found on rubydoc: https://rubydoc.info/github/gregmolnar/prepper.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test 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.
