Create a playbook to override the default inventory SSH port by using a special variable at runtime.

# playbook.yml
- name: Test connection with overridden SSH port hosts: web1
tasks:
- ping:
Execution:
ansible-playbook -i inventory.yml playbook.yml -e "ansible_port=2022"
Explanation:
Passing ansible_port as an extra variable ensures runtime overrides without altering the inventory.

Validate the configuration of group_vars for web_servers.

ansible-inventory -i inventory.yml --graph
Explanation:
ansible-inventory --graph displays the host and group hierarchy, confirming the correct application of variables.

Run a command on the control node but store the result in the context of a managed host.

- name: Store control node result hosts: web1
tasks:
- name: Get disk usage on control node
command: df -h
delegate_to: localhost
register: disk_usage
- name: Show disk usage debug:
var: disk_usage
Explanation:
This task demonstrates delegating commands to the control node while retaining results within the managed host's context.

Make a file named config.txt in the cloned repository, add sample configuration details, and commit the file with the message "Add initial config".

cd /home/user/projects/repo
echo "server=127.0.0.1" > config.txt
git add config.txt
git commit -m "Add initial config"
Explanation:
New files must be staged with git add before committing. The git commit command saves the changes with a descriptive message.

Use delegate_to to copy a file from the control node to a managed node.

- name: Copy file using delegation hosts: web1
tasks:
- name: Copy file to db1 copy:
src: /tmp/example.txt
dest: /tmp/example.txt delegate_to: db1
Explanation:
The task uses the copy module to transfer files from the control node to db1, delegating the task regardless of the web1 context.
