When kolla-ansible bootstrap-servers is run, it executes one of the
following two tasks:
- name: Ensure node_config_directory directory exists for user kolla
file:
path: "{{ node_config_directory }}"
state: directory
recurse: true
owner: "{{ kolla_user }}"
group: "{{ kolla_group }}"
mode: "0755"
become: True
when: create_kolla_user | bool
- name: Ensure node_config_directory directory exists
file:
path: "{{ node_config_directory }}"
state: directory
recurse: true
mode: "0755"
become: True
when: not create_kolla_user | bool
On the first run, normally node_config_directory (/etc/kolla/) doesn't
exist, so it is created with kolla:kolla ownership and 0755 permissions.
If we then run 'kolla-ansible deploy', config files are created for
containers in this directory, e.g. /etc/kolla/nova-compute/. Permissions
for those files should be set according to 'config_owner_user' and
'config_owner_group'.
If at some point we again run kolla-ansible bootstrap-servers, it will
recursively set the ownership and permissions of all files in /etc/kolla
to kolla:kolla / 0755.
The solution is to change bootstrap-servers to not set the owner and
permissions recursively. It's also arguable that /etc/kolla should be
owned by 'config_owner_user' and 'config_owner_group', rather than
kolla:kolla, although that's a separate issue.

Kolla-Ansible Overview
The Kolla-Ansible is a deliverable project separated from Kolla project.
Kolla-Ansible deploys OpenStack services and infrastructure components in Docker containers.
Kolla's mission statement is:
To provide production-ready containers and deployment tools for operating
OpenStack clouds.Kolla is highly opinionated out of the box, but allows for complete customization. This permits operators with little experience to deploy OpenStack quickly and as experience grows modify the OpenStack configuration to suit the operator's exact requirements.
Getting Started
Learn about Kolla-Ansible by reading the documentation online Kolla-Ansible.
