Lookups

py_pkgs

The py_pkgs lookup crawls a given list of directories to parse variables and generate lists of Python packages, git repo information and Ansible group memberships which is used within OpenStack-Ansible's repo_build role to build wheels and virtual environments.

Files and paths containing the following strings are evaluated:

• test-requirements.txt
• dev-requirements.txt
• requirements.txt
• global-requirements.txt
• global-requirement-pins.txt
• /defaults/
• /vars/
• /user*

Variables parsed within any evaluated files include:

• service_pip_dependencies
• pip_common_packages
• pip_container_packages
• pip_packages

Example

- name: Load local packages
  debug:
    msg: "Loading Packages"
  with_py_pkgs: "{{ pkg_locations }}"
  register: local_packages
  vars:
    pkg_locations:
      - "/etc/ansible/roles/os_nova"
