I’m not sure about using `latest` for packages, could cause issues.

I hope I remember to use the correct variables in the `index.html.j2` file; I think it was something like `{{ ansible_facts.fqdn }}` for the hostname.

I think we did a similar question where we had to set up a web server, but I can't recall if we used the `firewalld` module or something else.

I think I've got a good handle on this. The key will be to take it step-by-step, test each piece as I go, and make sure the playbook runs without any syntax errors. Can't wait to see the final result!

This looks like a good opportunity to practice using Ansible's import_tasks functionality to keep my main.yml file clean and modular. I'll make sure to create separate task files for each logical component.

Ah, the template file for the index.html is a nice touch. I'll need to make sure I get the variable substitution right for the hostname and IP address. Shouldn't be too difficult, but I'll double-check the Jinja2 syntax.

This looks like a pretty straightforward task. I think I can handle this by creating the role structure, defining the variables, and then building out the tasks to install the packages, configure the services, and generate the index.html file.

Hmm, I'm a bit unsure about the firewall configuration. Do I need to create a separate task for that or can I just include it in the service tasks? I'll need to review the firewall module documentation to make sure I'm doing that correctly.
