Thank you Brian for your reply.
Based on your suggestions, i created this playbook:
(create two groups and then apply the role to each subset)
- hosts: all
remote_user: root
gather_facts: false
tasks:
- ping:
register: rootlogin
ignore_errors: true
- group_by: key=fedora-user
when: rootlogin|failed
- group_by: key=root-user
when: rootlogin|success
- name: Execute play for CentOS instances
hosts: root-user
remote_user: root
roles:
- { role: path/to_role }
- name: Execute play for Fedora instances
hosts: fedora-user
remote_user: fedora
sudo: yes
sudo_user: root
roles:
- { role: path/to_role }
The problem is that only the root-user group it is created.
created 'group_by' ActionModule: key=stage-root-user
No fedora-user group was created. When it comes the time to execute the rol
for the fedora instances.
skipping: no hosts matched
I did also tried, create the two groups using multi plays(same idea), but
the groups were created with the same elements:
- name: Group CentOS instances
hosts: all
remote_user: root
gather_facts: no
# ignore_errors: true
tasks:
- name: remote_user is root
group_by: key=root_user
ignore_errors: true
- name: Group Fedora instances
hosts: all
gather_facts: no
remote_user: fedora
sudo: yes
sudo_user: root
tasks:
- name: remote_user is fedora
group_by: key=fedora_user
ignore_errors: true
- name: Execute play for CentOS instances
hosts: root_user
remote_user: root
roles:
- { role: path/to_role }
- name: Execute play for Fedora instances
hosts: fedora_user
remote_user: fedora
sudo: yes
sudo_user: root
roles:
- { role: path/to_role }
FATAL: no hosts matched or all hosts have already failed -- aborting
Thank you!
