11.5 Playbook — Nginx welcome for badge API

By Last updated: 

# playbooks/web_welcome.yml
- name: Configure badge API welcome web
  hosts: badge-api_web
  become: true

  tasks:
    - name: Ensure Nginx package is installed
      ansible.builtin.yum:
        name: nginx
        state: present
      # On Ubuntu use ansible.builtin.apt with update_cache: true

    - name: Deploy welcome index
      ansible.builtin.copy:
        dest: /usr/share/nginx/html/index.html
        mode: "0644"
        content: |
          <!DOCTYPE html>
          <html><body>
          <h1>Instagram-style badge API</h1>
          <p>Lab welcome page for the badge API course lab.</p>
          </body></html>

    - name: Ensure Nginx is started and enabled
      ansible.builtin.service:
        name: nginx
        state: started
        enabled: true

Run:

ansible-playbook -i inventory/hosts.ini playbooks/web_welcome.yml

Steps — first playbook success

  1. Confirm SSH to the target works with the inventory user.
  2. Create inventory/hosts.ini and playbooks/web_welcome.yml.
  3. Match package module to the OS (Amazon Linux family → yum/dnf module as appropriate; Ubuntu → apt).
  4. ansible-playbook … and read the recap: ok / changed / failed.
  5. From your laptop: curl -I http://TARGET:80 (shop counter 80) — expect success if SG allows your IP (AWS course SG skills).
  6. Run the playbook a second time — expect mostly ok, little changed.

What you see: Browser or curl shows the badge API welcome heading. Second run is boring — that is success.

Deep Nginx tuning, TLS, and multi-site hosting stay in the AWS Cloud web chapters — here Nginx is only a configuration target.

Path /usr/share/nginx/html distro-nuusar thoda vegla asu shakto. Fail zala tar nginx -V / distro doc check kara — guess karu nako. Lakshat theva!
