In this step will deploy a placeholder web application to the servers.

deploy a web page to simulate an app

Open each VM IP address in a web browser and confirm you see the standard phpinfo() page. (i.e., http:<IPADDRESS> The following playbook will confirm a page with HTTP status 200 is returned (but not the contents) <file yaml check_fleet.yml> — - hosts: all become: true tasks: - name: Check web server status on port 80 uri: url: http:inventory_hostname:80/ follow_redirects: no register: web_status - name: Assert 200 HTTP status code assert: that: web_status.status == 200 msg: “Expected HTTP 200 status code, but got web_status.status.
