Now I want to execute that role on host 192.168.0.10 from the command line from Ansible host

Answer 1

Have you tried that? it's super cool. I'm using 'update-os' instead of 'apache' role to give a more meaningful example. I have a role called let's say ./roles/update-os/ in my ./ I add a file called ./role-update-os.yml which looks like:

#!/usr/bin/ansible-playbook
---
- hosts: all
  gather_facts: yes
  become: yes
  roles:
  - update-os

Make this file executable (chmod +x role-update-os.yml). Now you can run and limit to whatever you have in your inventory ./update-os.yml -i inventory-dev --limit 192.168.0.10 the limit you can pass the group names as well.

• --limit web,db > web and db is the group defined in your inventory
• --limit 192.168.0.10,192.168.0.201

$ cat inventory-dev
[web]
192.168.0.10

[db]
192.168.0.201

Note that you can configure ssh-keys and sudoers policy to be able to execute without having to type password - ideal for automation, there are security implications with this. therefore you have to analyze your environment to see whether it's suitable.
