Need help installing Role from a collection

[uconn-alf02013]

i was messing around here https://rol.redhat.com/rol/app/courses/rh294-9.0/pages/ch10s05
and took the file redhat-rhel_system_roles-1.19.3.tar.gz  from review-cr3 and tried to use it in review-cr4.
Should what i am doing be possible ??

i was able to run this and see the collection added

ansible-galaxy collection install redhat-rhel_system_roles-1.19.3.tar.gz -p coll

[student@workstation review-cr4]$ ansible-galaxy collection list

# /home/student/review-cr4/coll/ansible_collections
Collection Version
------------------------ -------
redhat.rhel_system_roles 1.19.3

# /usr/share/ansible/collections/ansible_collections
Collection Version
------------------------ -------
redhat.rhel_system_roles 1.16.2

Then i tried to add this file

[student@workstation roles]$ more requirements.yml
- src: redhat-rhel_system_roles-1.19.3.tar.gz
name: postfix
[student@workstation roles]$ pwd
/home/student/review-cr4/roles

Then i crash here

ansible-galaxy role install -r requirements.yml

[student@workstation roles]$ ansible-galaxy role install -r requirements.yml
Starting galaxy role install process
- downloading role 'gz', owned by redhat-rhel_system_roles-1.19.3.tar

ERROR! - you can use --ignore-errors to skip failed roles and finish processing the list.

I just did this hack to get it to work....is this a bad way to do it ?


cp -rf coll/ansible_collections/redhat/rhel_system_roles/roles/postfix/ ./roles/

then i ran this file

[student@workstation review-cr4]$ more site.yml
---
- name: Play to call role
hosts: webdev

roles:
- postfix

Then i ssh to serverb and serverc and ran "ss -ltn" and postfix is installed started enabled and running.

Looks like Ch7. in the RH294 PDF file has a "file" example. I got this to work.

[student@workstation roles]$ more requirements.yml 
- src: file:///home/student/review-cr4/redhat-rhel_system_roles-1.19.3.tar.gz
  name: postfix
