Iterate over a pip requirements.txt file

pip-iter.yaml

- name: Debug pip with large requirements file
  hosts: 127.0.0.1
  connection: local
  become: yes
  tasks:

    - name: Get the requirements file
      slurp:
        src: /opt/awx/requirements/requirements.txt
      register: reqfile

    - name: Install Python module requirements
      pip:
        name: "{{ item | regex_search('^(?P<mod>\\S*)==(?P<ver>\\S*)','\\g<mod>') | first }}"
        version: "{{ item | regex_search('^(?P<mod>\\S*)==(?P<ver>\\S*)','\\g<ver>') | first }}"
      with_items: "{{ (reqfile.content|b64decode).splitlines()|map('regex_replace', '\\s*#.*$', '')|list }}"
      when:
        - item is defined
        - item != ''

So run this as root with:

ansible-playbook pip-iter.yaml

https://docs.ansible.com/ansible/latest/modules/pip_module.html

Would this work?

- name: Install Python module requirements
  pip:
    requirements: /opt/awx/requirements/requirements.txt
    executable: pip

@gundalow Sorry, no because of ansible/ansible#42546

Will be fixed after pip 10.0.2 pypa/pip#5366 (comment)
