Is it possible to create python virtual environment with ansible playbook?
<p>I have tried to create virtual environment in vagrant VM using ansible-local, but failed.</p>

<p>This is my Vagrant file:</p>

<pre><code>Vagrant.configure(2) do |config|
  config.vm.provider "virtualbox" do |v|
    v.memory = 4096
    v.cpus = 2
  end

  config.vm.define "shortener" do |shortener|
    shortener.vm.box = "ubuntu/trusty64"
    # database 
    shortener.vm.network :forwarded_port, host: 3307, guest: 3306
    # browser
    shortener.vm.network :forwarded_port, host: 4568, guest: 4568
    shortener.vm.provision :ansible_local do |ansible|
        ansible.playbook = "playbook.yml"
    end
  end

  config.ssh.forward_agent = true

end
</code></pre>

<p>This is "playbook.yml":</p>

<pre><code>- name: Deploy shortener
  hosts: all
  become: true
  become_method: sudo

  tasks:
    - name: Install packages
      apt: update_cache=yes name={{ item }} state=present
      with_items:
    - git
    - python-pip
    - nginx-full
    - vim
    - python-virtualenv
    - virtualenvwrapper
    - python3.4
    - python3.4-doc
    - python3.4-dev
    - software-properties-common
    - python-software-properties
    - postgresql
    - postgresql-client

- name: Load virtualenvwrapper
  shell: source /etc/bash_completion.d/virtualenvwrapper

- name:  Create virtual environment               
  shell: mkvirtualenv shortener --python=/usr/bin/python3

- name: Install requirements
  pip: requirements='/vagrant/configs/requirements.txt'
</code></pre>

<p>And this is the output of 'vagrant up':</p>

Ansible failed to complete successfully. Any error output should be visible above. Please fix these errors and try again.
</code></pre>

<p>Also I tried to use '<code>command</code>' instead of '<code>shell</code>' with the same result.</p>

<p>I think I could use a shell script that creates virtualenvironment, but is it possible to fix that error with ansible means ?</p>

<p>I have found a solution. This is my "playbook.yml" file:</p>

<pre><code>- name: Deploy shortener
  hosts: all
  remote_user: vagrant

 tasks:
    - name: Install packages
      become: true
      become_method: sudo        
      apt: update_cache=yes name={{ item }} state=present
      with_items:
        - git
        - python-pip
        - nginx-full
        - vim
        - python-virtualenv
        - virtualenvwrapper
        - python3.4
        - python3.4-doc
        - python3.4-dev
        - software-properties-common
        - python-software-properties
        - postgresql
        - postgresql-client

    - name: Install requirements
      become: true
      become_method: sudo        
      pip: 
        requirements: /vagrant/configs/requirements.txt
        virtualenv: /home/vagrant/.virtualenvs/shortener
        virtualenv_python: python3.4
</code></pre>

<p>I have used standard pip module for that. Thanks for helpful comments!</p>

python vagrant ansible virtualenv ansible-local
