What is rvm1-ansible? Build Status

It is an Ansible role to install and manage ruby versions using rvm.

Why should you use rvm?

In production it's useful because compiling a new version of ruby can easily take upwards of 10 minutes. That's 10 minutes of your CPU being pegged at 100%.

rvm has pre-compiled binaries for a lot of operating systems. That means you can install ruby in about 1 minute, even on a slow micro instance.

This role even adds the ruby binaries to your system path when doing a system wide install. This allows you to access them as if they were installed without using a version manager while still benefiting from what rvm has to offer.

Installation

$ ansible-galaxy install rvm_io.ruby

Role variables

Below is a list of default values that you can configure:

---

# Install 1 or more versions of ruby
# The last ruby listed will be set as the default ruby
rvm1_rubies:
  - 'ruby-2.3.1'

# Install the bundler gem
rvm1_bundler_install: True

# Delete a specific version of ruby (ie. ruby-2.1.0)
rvm1_delete_ruby:

# Install path for rvm (defaults to single user)
# NOTE: If you are doing a ROOT BASED INSTALL then make sure you
#       set the install path to something like '/usr/local/rvm'
rvm1_install_path: '~/.rvm'

# Add or remove any install flags
# NOTE: If you are doing a ROOT BASED INSTALL then
#       make sure you REMOVE the --user-install flag below
rvm1_install_flags: '--auto-dotfiles  --user-install'

# Add additional ruby install flags
rvm1_ruby_install_flags:

# Set the owner for the rvm directory
# NOTE: If you are doing a ROOT BASED INSTALL then
#       make sure you set rvm1_user to 'root'
rvm1_user: 'ubuntu'

# URL for the latest installer script
rvm1_rvm_latest_installer: 'https://raw.githubusercontent.com/wayneeseguin/rvm/master/binscripts/rvm-installer'

# rvm version to use
rvm1_rvm_version: 'stable'

# Check and update rvm, disabling this will force rvm to never update
rvm1_rvm_check_for_updates: True

# GPG key verification, use an empty string if you want to skip this
# Note: Unless you know what you're doing, just keep it as is
#           Identity proof: https://keybase.io/mpapis
#           PGP message: https://rvm.io/mpapis.asc
rvm1_gpg_keys: '409B6B1796C275462A1703113804BB82D39DC0E3'

# The GPG key server
rvm1_gpg_key_server: 'hkp://keys.gnupg.net'

# autolib mode, see https://rvm.io/rvm/autolibs
rvm1_autolib_mode: 3

Example playbooks

---

- name: Configure servers with ruby support for single user
  hosts: all

  roles:
    - { role: rvm_io.ruby,
        tags: ruby,
        rvm1_rubies: ['ruby-2.3.1'],
        rvm1_user: 'ubuntu'
      }

If you need to pass a list of ruby versions, pass it in an array like so.

---
- name: Configure servers with ruby support system wide
  hosts: all
  roles:
    - { role: rvm_io.ruby,
        tags: ruby,
        become: yes

        rvm1_rubies: ['ruby-2.2.5','ruby-2.3.1'],
        rvm1_install_flags: '--auto-dotfiles'     # Remove --user-install from defaults
        rvm1_install_path: /usr/local/rvm         # Set to system location
        rvm1_user: root                           # Need root account to access system location
      }

rvm_rubies must be specified via ruby-x.x.x so that if you want ruby 2.2.5, you will need to pass in an array rvm_rubies: ['ruby-2.2.5']

System wide installation

The above example would setup ruby system wide. It's very important that you run the play as root because it will need to write to a system location specified by rvm1_install_path

To the same user as ansible_user

In this case, just overwrite rvm_install_path and by default is set the --user-install flag:

rvm1_install_flags: '--auto-dotfiles --user-install'
rvm1_install_path: '/home/{{ ansible_user }}/.rvm'

To a user that is not ansible_user

You will need root access here because you will be writing outside the ansible user's home directory. Other than that it's the same as above, except you will supply a different user account:

rvm1_install_flags: '--auto-dotfiles --user-install'
rvm1_install_path: '/home/someuser/.rvm'

A quick note about rvm1_user

In some cases you may want the rvm folder and its files to be owned by a specific user instead of root. Simply set rvm1_user: 'foo' and when ruby gets installed it will ensure that foo owns the rvm directory.

Upgrading and removing old versions of ruby

A common work flow for upgrading your ruby version would be:

  1. Install the new version
  2. Run your application role so that bundle install re-installs your gems
  3. Delete the previous version of ruby

Leverage ansible's --extra-vars

Just add --extra-vars 'rvm1_delete_ruby=ruby-2.1.0' to the end of your play book command and that version will be removed.

Requirements

  • Tested on ubuntu 12.04 LTS but it should work on other versions that are similar.
  • Tested on RHEL6.5 and CentOS [6.5, 6.6, 6.7]
