[openstack-ansible-ops] cleanup-venv playbook removes wsgi venv

[Gilles Mocellin]

After upgrading from rocky to ussuri, via all intermediates with openstack-ansible, I wanted to clean all the old venvs in /openstack/venvs in every server/container.

I use this playbook from the openstack-asnsible-ops project : cleanup-venvs.yml.

But, what I have not seen until I had to restart a service, it had removed /openstack/venvs/uwsgi-21.1.0-python3.

The task that must be adapted :

- name: Remove older venvs
  hosts: all
  tasks:
  - name: List venvs directories
    find:
      paths: /openstack/venvs
      file_type: directory
      patterns: '.*(?<!{{ venv_tag }})$'
      use_regex: yes
    register: result
  - name: Delete older directories
    file:
      path: "{{ item.path }}"
      state: absent
    with_items: "{{ result.files }}"

The file pattern does not match the wsgi venv because it doesn't ends with the version, but with -python3.

Can i try upgrade two version together ? Ex: From Train to Victoria version directly instead of going step by step upgrade

While it's not officially supported, I've upgraded several of my environments from T to V without serious issues.
The things you should look after is wrong record for rabbitmq which involves localhost in /etc/hosts inside rabbitmq container after setup-hosts.yml is ran, and possible issues with cinder db migrate that should be solved manually by setting cluster (or volume type) name iirc for volumes that were deleted before this row has been introduced in cinder (if you deployed on R or before that).
