Ubuntu 14.04 and Default Variable not Set

[Ray Hooker]

I am trying to debug a problem with installing OpenEdX on Ubuntu 14.04.  The same set of playbooks work find on Ubuntu 12.04 BTW.  A task was failing apparently because the environment variables were not set.  The task is using rbenv.  The environment is set as follows:

edxapp_environment:

  LANG: $EDXAPP_LANG

  NO_PREREQ_INSTALL: $EDXAPP_NO_PREREQ_INSTALL

  SKIP_WS_MIGRATIONS: 1

  RBENV_ROOT: $edxapp_rbenv_root

  GEM_HOME: $edxapp_gem_root

  GEM_PATH: $edxapp_gem_root

  PATH: $edxapp_deploy_path

I did a debug as the first step of the main.yml tasks file for the edxapp role.  The output was:

First the debug:

- name: Display edxapp_env

  debug: msg="The EDXAPP Env is {{edxapp_environment}}!"

then the output...

TASK: [edxapp | Display edxapp_env] *******************************************

ok: [localhost] => {

    "item": "",

    "msg": "The EDXAPP Env is {'LANG': '$EDXAPP_LANG', 'SKIP_WS_MIGRATIONS': 1, 'GEM_PATH': '$edxapp_gem_root', 'NO_PREREQ_INSTALL': '$EDXAPP_NO_PREREQ_INSTALL', 'PATH': '$edxapp_deploy_path', 'GEM_HOME': '$edxapp_gem_root', 'RBENV_ROOT': '$edxapp_rbenv_root'}!"

}

What is funny is that debug statement for $edxapp_rbenv_root shows that it is properly set even though for some reason it does not create the edxapp_environment variable correctly.    **** BTW I did a debug of complex variables before and after edxapp_environment and they are set correctly.

Any help or suggestions on how to debug this problem would be appreciated.

$foo variables have not been used in Ansible for some time.

This is an out of date playbook.
