2.9. Copying a HTML file to the Web Host

The HTTP server configuration is now complete. This provides a platform for installing a web-based application, which Puppet can also configure. For this example, however, we will only copy over a simple index webpage to our web host.
Create file named index.html in the files directory. Add the following content to this file: 
<html>
  <head>
    <title>Congratulations</title>
  <head>
  <body>
    <h1>Congratulations</h1>
    <p>Your puppet module has correctly applied your configuration.</p>
  </body>
</html>
Create manifest named app.pp in the manifests directory. Add the following content to this file: 
class mymodule::app {
  file { "/var/www/myserver/index.html":
    ensure => file,
    mode   => 755,
    owner  => root,
    group  => root,
    source => "puppet:///modules/mymodule/index.html",
    require => Class["mymodule::httpd"],
  }
}
This new class contains a single resource declaration. This declaration copies a file from the module's file directory from the Puppet server to the system and sets its permissions. Additionally, the require attribute ensures the mymodule::http class completes configuration successfully before we apply mymodule::app.
Finally, include this new manifest in our main init.pp manifest: 
class mymodule (
  $http_port = 80
) {
  include mymodule::httpd
  include mymodule::app
}
Run the puppet apply command again to test the changes to our module. The output should resemble the following: 
# puppet apply mymodule/tests/init.pp --noop
