ansible pip：在虚拟环境中递归安装轮子

Question

To install all wheels from a folder /tmp/prod_wheel/ I do this:

$ cat playbook_install.yml
---
- hosts: localhost
  tasks:

    - name: Install all wheels
      pip:
        name: "{{ query('fileglob', '/tmp/prod_wheel/*.whl') }}"
        virtualenv: "~/venv"
        virtualenv_command: /usr/bin/python3 -m venv ~/venv

It's working well.

Now I have a situation where wheels are in folders I don't known the names, eg /tmp/data/*/*.whl the fileglob does not glob folders (only files).

I use find to catch wheels, but what is the more compact way to install them in my virtualenv?

$ echo playbook_catch_wheels.yml
---
- hosts: localhost
  tasks:

    - name: Find to catch recursively all wheels
      find:
        paths: /vagrant/vagrant/*/dist/
        patterns: '*.whl'

You can simply extract the list of paths from your find result with the map filter and pass it to pip , as you previously did with your fileglob lookup.

Taking for granted your actual find task returns what you expect (I still added recurse since you mentioned it) the following two tasks should meet your requirement:

---
- hosts: localhost
  tasks:

    - name: Find to catch recursively all wheels
      find:
        paths: /vagrant/vagrant/*/dist/
        patterns: '*.whl'
        recurse: true
      register: wheel_search

    - name: Install all found wheels
      pip:
        name: "{{ wheel_search.files | map(attribute='path') | list }}"
        virtualenv: "~/venv"
        virtualenv_command: /usr/bin/python3 -m venv ~/venv

Note that the find solution is much more portable than the fileglob lookup, as it will work on a remote host if needed. Lookups are always running locally whereas find runs on the target host.
