Working With Language-Specific Version Managers
===============================================
Some language-specific version managers (such as rbenv and nvm) require environment variables be set while these tools are in use. When using these tools manually, they usually require sourcing some environment variables via a script or lines added to your shell configuration file. In Ansible, you can instead use the environment directive::
---
### A playbook demonstrating a common npm workflow:
# - Check for package.json in the application directory
# - If package.json exists:
# * Run npm prune
# * Run npm install
- hosts: application
become: false
vars:
node_app_dir: /var/local/my_node_app
environment:
NVM_DIR: /var/local/nvm
PATH: /var/local/nvm/versions/node/v4.2.1/bin:{{ ansible_env.PATH }}
tasks:
- name: check for package.json
stat:
path: '{{ node_app_dir }}/package.json'
register: packagejson
- name: npm prune
command: npm prune
args:
chdir: '{{ node_app_dir }}'
when: packagejson.stat.exists
- name: npm install
npm:
path: '{{ node_app_dir }}'
when: packagejson.stat.exists
You might also want to simply specify the environment for a single task::
---
- name: install ruby 2.3.1
command: rbenv install {{ rbenv_ruby_version }}
args:
creates: '{{ rbenv_root }}/versions/{{ rbenv_ruby_version }}/bin/ruby'
vars:
rbenv_root: /usr/local/rbenv
rbenv_ruby_version: 2.3.1
environment:
CONFIGURE_OPTS: '--disable-install-doc'
RBENV_ROOT: '{{ rbenv_root }}'
PATH: '{{ rbenv_root }}/bin:{{ rbenv_root }}/shims:{{ rbenv_plugins }}/ruby-build/bin:{{ ansible_env.PATH }}'
