hub_namespaces
In this file we prepare the new namespace to load custom collections into.
group_vars/all/hub_namespaces.yml
We create a new namespace to hold the custom collections for our enterprise, you have a choice here to create more if you want.

hub_namespaces_all:
- name: wf_linux
company: WF linux
email: wilco.folkers@homelab
avatar_url: https://static.redhat.com/libs/redhat/brand-assets/latest/corp/logo.svg
description: Namespace for my collections
resources: "# WF linux\nA Namespace for testing collections"
...
But you can already see that the variable name used here has the "_all" extension, so the variable will not be overridden as this is not quite a inventory.
Why we do this, will become clear in a moment.
group_vars/dev/hub_namespaces.yml
As we do not configure extra namespaces for the dev environment, this file is an empty set.
---
hub_namespaces_dev: []
# No extra config exists
...
Here the variable has the "_dev" extension, so the variable will not be overridden.
group_vars/prod/hub_namespaces.yml
As we do not configure extra namespaces for the prod environment, this file is an empty set.
---
hub_namespaces_prod: []
# No extra config exists
...
Here the variable has the "_prod" extension, so the variable will not be overridden.
When we run a pipeline for a certain environment, the inventory structure will provide us with 2 variables:
- hub_namespaces_all
- hub_namespaces_
We will merge these 2 variables into 1: hub_namespaces and feed this to the infra.aap_configuration.hub_namespaces role.
In main.yml the merge of the variables is done by this piece of code:
- name: Set the gateway vars
ansible.builtin.set_fact:
hub_namespaces: >
{{ hub_namespaces_all |
community.general.lists_mergeby(vars['hub_namespaces_' + branch_name],
'name', recursive=true, list_merge='append') }}
This results in the hub_namespaces variable the collection needs.
