Ansible command from inside virtualenv?

Question

This seems like it should be really simple:

tasks: - name: install python packages   pip: name=${item} virtualenv=~/buildbot-env   with_items: [ buildbot ] - name: create buildbot master   command: buildbot create-master ~/buildbot creates=~/buildbot/buildbot.tac 

However, the command will not succeed unless the virtualenv's activate script is sourced first, and there doesn't seem to be provision to do that in the Ansible command module.

I've experimented with sourcing the activate script in various of .profile, .bashrc, .bash_login, etc, with no luck. Alternatively, there's the shell command, but it seems like kind of an awkward hack:

- name: create buildbot master   shell: source ~/buildbot-env/bin/activate && \          buildbot create-master ~/buildbot \          creates=~/buildbot/buildbot.tac executable=/bin/bash 

Is there a better way?

The better way is to use the full path to installed script - it will run in its virtualenv automatically:

tasks: - name: install python packages   pip: name={{ item }} virtualenv={{ venv }}   with_items: [ buildbot ] - name: create buildbot master   command: "{{ venv }}/bin/buildbot create-master ~/buildbot             creates=~/buildbot/buildbot.tac"
