ruby-builder

Ansible Playbook to deploy ruby to Debian or RHEL Based systems via the ruby-build tool.

If you are like me and have to manage multiple linux distributions across Production, Staging, and Development and find default packages for ruby installs a nightmare to work with then this may be for you.

This approach was spawned out of mostly a hatred for RVM, Rbenv and all the other ruby version managers etc. and the attempt to simplify the overall server installs in a clean, streamline, and replicable way.

This uses the ruby-build tool (https://github.com/sstephenson/ruby-build) to handle the source intsalls and will be updated automatically every time this playbook is run to ensure it has the latest ruby definitions.

Abridged Version of what this does

1. Installs packages required for ruby to be installed
2. Installs the ruby-build tool
3. Installs Ruby From Source to /usr/local/ruby-$VERSION
4. Links the source ruby install to /usr/local/ruby for easy reference
5. Updates the /etc/environments to ensure the ruby path is exported
6. Updates /etc/sudoers to let the ruby binares be accessible w/ sudo

The play is smart enough to see if ruby is already installed it will skip the source installation.

Role Variables

This play inclues variables for RHEL / Deb required packages as well as two default variables.

All variables are prefixed with the name of the play "ruby_builder"

Default Variables

---
ruby_builder_ruby_version: 2.1.0
ruby_builder_environment_path: "/usr/local/ruby/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

ruby_builder_version = The version of ruby to be installed

ruby_builder_environment_path = The path to set in /etc/environment used by templates/environment.j2

Variables in vars/main.yml

I would advise against changing these as they shouldn't need modified.

I am more fluent with RHEL based systems so its more minimalistic than the Debian based systems.
