Install RVM with ansible

Question

I am attempting to install rvm with ansible on a centos-based vagrant box.

The command I am running is:

vars:
  user: "foo"

- name: install rvm
  action: command sudo -u $user bash /home/$user/rvm-install.sh stable creates=$home/.rvm

It pretty much works BUT Ansible thinks it has failed.

Ansible output is:

failed: [127.0.0.1] => {"changed": true, "cmd": ["sudo", "-u", "foo", "bash", "/home/foo/rvm-install.sh", "stable"], "delta": "0:00:21.102322", "end": "2012-10-09 12:33:19.917874", "rc": 1, "start": "2012-10-09 12:32:58.815552"}

# In case of any issues read output of 'rvm requirements' and/or 'rvm notes'

Installation of RVM in /home/foo/.rvm/ is almost complete:

  * To start using RVM you need to run `source /home/foo/.rvm/scripts/rvm`
    in all your open shell windows, in rare cases you need to reopen all shell windows.

# root,

#   Thank you for using RVM!
#   I sincerely hope that RVM helps to make your life easier and more enjoyable!!!

RVM & Ruby Installation Playbook

Here's an idempotent playbook that will install RVM, a specific version of Ruby (set the version with the ruby_version var) and set that version of Ruby to be the default:

---

- hosts: all
  sudo: yes
  vars:
    ruby_version: "2.1.3"
    rvm_path: "/usr/local/rvm/gems/ruby-{{ ruby_version }}/bin:/usr/local/rvm/gems/ruby-{{ ruby_version }}@global/bin:/usr/local/rvm/rubies/ruby-{{ ruby_version }}/bin:/usr/local/rvm/bin"

  tasks:

  - name: append rvm path to environment
    lineinfile: dest=/etc/environment state=present backrefs=yes regexp='PATH=(["]*)((?!.*?{{rvm_path}}).*?)(["]*)$' line="PATH=\1\2:{{rvm_path}}\3"


  - name: ensure necessary packages are installed
    yum:
      name: "{{ item }}"
      state: present
    with_items:
      - curl
      - gnupg2

  - name: ensure that GPG key for RVM is installed
    command: gpg2 --keyserver hkp://keys.gnupg.net --recv-keys D39DC0E3
    args:
      creates: /root/.gnupg/secring.gpg

  - name: ensure that RVM is installed
    shell: curl -L get.rvm.io | bash -s stable
    args:
      creates: /usr/local/rvm

  - name: ensure that ruby is installed
    command: "rvm install {{ ruby_version }}"
    args:
      creates: "/usr/local/rvm/gems/ruby-{{ ruby_version }}"
    environment:
      PATH: "{{ rvm_path }}:{{ ansible_env.PATH }}"

  - name: set default version of ruby with rvm
    command: "rvm alias create default ruby-{{ ruby_version }}"
    args:
      creates: /usr/local/rvm/config/alias
    environment:
      PATH: "{{ rvm_path }}:{{ ansible_env.PATH }}"

Solution 2

This worked for me (Ubuntu):

    tasks:
      - name: Install RVM
        shell: "curl -sSL https://get.rvm.io | bash"

Using a regular (non-root) user.

Solution 3

These days, I believe the recommended way is with RVM's ansible role. There are instructions in that project's README.

Solution 4

Building on @dynex's answer, here's a way to do it a bit more idempotently, by checking for a folder it would normally create.

- stat: path=/etc/profile.d/rvm.sh
  register: rvm_folder

- name: install rvm
  shell: "curl -sSL https://get.rvm.io | bash"
  when: rvm_folder.stat.isdir is not defined

Solution 5

I also tried installing RVM with Ansible. Unfortunately RVM doesn't play nicely with non-interactive shells, because it is a shell script function. I ended up installing rbenv instead (https://github.com/sstephenson/rbenv).

Yeah took me a while, but got it to work (non-global, single user). Here's the gist and the blog: gist.github.com/ihassin/7968406. Blog at ihassin.wordpress.com/2013/12/15/…

that gist and blog post don't use this and don't use RVM. It says that's intended for a later post.

[dynex]

I'm sorry, you'r right - I changed the blog not to use RVM and wanted to do a separate write up for RVM. When I was testing with RVM, the above worked, but not "system-wide" for which you need "shell: "curl -sSL get.rvm.io | sudo bash". Sorry for the confusion and I will remove the link to the gist.

Nice :) Ansible is full of hidden gems. Pun intended...

[anquegi]

Thanks for this solution, it works for me, but I cannot install gems from the ansible playbook, it always give me an error. How can I install gems to a gemset from ansible playbook
