**How to install collections that are compatible with the version of ansible-core and python in my EE container**.

IIRC, for a python `requirements.txt` file you can specify a python module version restriction that is compatible with the version of python used to install the module.

I am looking for the same type of functionality (if it exists) to limit the versions of collections installed using the `collections\requirements.yml` file.

I know I can specify limits on a collection version with:

```auto
---
collections:
  - name: foo.bar
    version: ">=2.2.0,<3.0.0"

```

This will install newest version of `foo.bar` that is less than version 3.

Is there a way to have `ansible-galaxy` _also_ limit a collection version to what is compatible with the version of `ansible-core` and `python` that is installed in the container? For instance:

```auto
collections:
  - name: foo.bar
    version: ">=2.2.0,<3.0.0,ansible=2.15,python=3.9"

```

This doesn’t work but should illustrate my point.

Follow-on question. **How do you keep track of what collection versions are compatible with your version of Ansible and Python?**

Thank you!
