Puppet Docker PHP Apache setup - Invalid command 'RewriteRule', perhaps misspelled or defined

Question

I am using puppet docker (https://forge.puppet.com/modules/puppetlabs/docker) and setup PHP-Apache website using PHP docker image (https://hub.docker.com/layers/php/library/php/7.2.34-apache/images/sha256-77e5a326252f951aa557f48829973f67e8efde9c52f81ee4e4a5473a59a217d9?context=explore)

The PHP script works fine but when I added .htaccess file in folder, it is throwing error

I believe I need to RUN a2enmod rewrite as in here (https://stackoverflow.com/a/38064289/376702)

I don't know how can I set up using puppet docker(https://forge.puppet.com/modules/puppetlabs/docker).

Can anyone please guide me? Here is my puppet code.

 docker::image { 'docker.io/php':
    image_tag => '7.2.34-apache'
  }

  docker::run { 'test123.com':
    image            => 'docker.io/php:7.2.34-apache',
    command          => 'apache2-foreground',
    expose           => ['80'],
    ports            => ['8101:80'],
    volumes          => ['/var/www/test123.com:/var/www/html'],
    hostname         => 'test123.com',
    restart_service  => true,
    before_stop      => 'echo "So Long, and Thanks for All the Fish"',
    before_start     => 'echo "Run this on the host before starting the Docker container"',
    after_stop       => 'echo "container has stopped"',
    after_start      => 'echo "container has started"',
    extra_parameters => [ '--restart=always' ],
  }

I am running docker in Linux RedHat

If you need to RUN a2enmod rewrite in the Dockerfile, then that would likely be most achieveable in a multi-stage build, and you can manage the resulting image from the new Dockerfile in Puppet. Modifying the Dockerfile of an image from the official repository is likely not possible in Puppet (or otherwise) without extensive additional coding. — Matt Schuchard

I rebuild PHP apache official image with the following configuration

# Dockerfile

FROM docker.io/php:7.2.34-apache
RUN a2enmod rewrite

puppet code changes in pp puppet class

      docker::image { 'php-apache7234':
        docker_file => '/tmp/Dockerfile',
        subscribe   => File['/tmp/Dockerfile'],
      }
    
      file { '/tmp/Dockerfile':
        ensure => file,
        source => 'puppet:///modules/mydocker/php_apache/Dockerfile',
      }

  docker::run { 'test123.com':
    image            => 'php-apache7234',
    command          => 'apache2-foreground',
    expose           => ['80'],
    ports            => ['8101:80'],
    volumes          => ['/var/www/test123.com:/var/www/html'],
    hostname         => 'test123.com',
    restart_service  => true,
    before_stop      => 'echo "So Long, and Thanks for All the Fish"',
    before_start     => 'echo "Run this on the host before starting the Docker container"',
    after_stop       => 'echo "container has stopped"',
    after_start      => 'echo "container has started"',
    extra_parameters => [ '--restart=always' ],
  }
