You can list the virtual environments on your automation controller instance using the awx-manage command.

Procedure

  1. SSH into your automation controller instance and run: 

    $ awx-manage list_custom_venvs
    Copy to Clipboard Toggle word wrap

A list of discovered virtual environments will appear. 

# Discovered virtual environments:
/var/lib/awx/venv/testing
/var/lib/venv/new_env

To export the contents of a virtual environment, re-run while supplying the path as an argument:
awx-manage export_custom_venv /path/to/venv
Copy to Clipboard Toggle word wrap

    $ awx-manage custom_venv_associations /path/to/venv
    Copy to Clipboard Toggle word wrap

A list of associated objects will appear. 

inventory_sources:
- id: 15

Select the custom virtual environment you wish to export using awx-manage export_custom_venv command.

Procedure

  1. SSH into your automation controller instance and run: 

    $ awx-manage export_custom_venv /path/to/venv
    Copy to Clipboard Toggle word wrap

The output from this command will show a pip freeze of what is in the specified virtual environment. This information can be copied into a requirements.txt file for Ansible Builder to use for creating a new automation execution environments image 

numpy==1.20.2
pandas==1.2.4
python-dateutil==2.8.1
pytz==2021.1
six==1.16.0

To list all available custom virtual environments run:
awx-manage list_custom_venvs
Copy to Clipboard Toggle word wrap
Note

Pass the -q flag when running awx-manage list_custom_venvs to reduce output.

7.2. Migrating between Ansible Core versions
Copiar enlace

Migrating between versions of Ansible Core requires you to update your playbooks, plugins and other parts of your Ansible infrastructure to ensure they work with the latest version. This process requires that changes are validated against the updates made to each successive version of Ansible Core. If you intend to migrate from Ansible 2.9 to Ansible 2.11, you first need to verify that you meet the requirements of Ansible 2.10, and from there make updates to 2.11.

7.2.1. Ansible Porting Guides
Copiar enlace

The Ansible Porting Guide is a series of documents that provide information on the behavioral changes between consecutive Ansible versions. Refer to the guides when migrating from version of Ansible to a newer version.
