Title: dockerized wordpress problem Last modified: January 31, 2024 --- # dockerized wordpress problem * [khrob](https://wordpress.org/support/users/khrob/) * (@khrob) * [2 years, 4 months ago](https://wordpress.org/support/topic/dockerized-wordpress-problem/) * Good morning, I work at a small development company and we would like to start dockerizing our applications. * Among other things, we are trying to dockerize wordpress for a client’s website. * We have used the following docker-compose file: * ```wp-block-code version: '3' services: cosde_wp: image: wordpress:6.4.1 container_name: cosde_wp ports: - 82:80 restart: unless-stopped environment: - WORDPRESS_DB_HOST=ip_db:3306 - WORDPRESS_DB_USER=user - WORDPRESS_DB_PASSWORD=password - WORDPRESS_DB_NAME=db_name volumes: - ./wp-data:/var/www/html:rw ``` * The server running Docker is a Debian 11 Bullseye VM. The database is hosted on a separate server. * Everything is pretty basic; the container starts, we did the initial settings and created the WordPress user for the client’s external designer who will be creating the actual website. * The designer installed the Elementor plugin, and this is where the problems begin. Every time a page is created or modified, the error “The preview cannot be loaded” appears. I have done some tests and I can create pages and upload images, but it seems that the pages have no formatting. Even after downloading and applying a theme, the pages appear to be unformatted. * If it may be helpful, these are the permissions of the wp-data directory: `drwxr- xr-x 5 www-data www-data 4096 Jan 31 10:32 wp-data` * Can someone kindly tell me if there are any specific settings needed to make dockerized WordPress work correctly? Is it necessary to apply specific privileges to the folders inside the container? Or is what happens an error of the Elementor plugin? * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fdockerized-wordpress-problem%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 3 replies - 1 through 3 (of 3 total) * [luk4](https://wordpress.org/support/users/luk4/) * (@luk4) * [2 years, 4 months ago](https://wordpress.org/support/topic/dockerized-wordpress-problem/#post-17388351) * Hi [@michel225](https://wordpress.org/support/users/michel225/) * Be sure WordPress is able to [loopback to itself](https://developer.wordpress.org/advanced-administration/wordpress/loopback/). From my experience, that’s usually the main issue on Docker environements with a reverse proxy. * To check this, go to Tools › [Site Health](https://wordpress.org/documentation/article/site-health-screen/). You might be warned about other relevant issues as well there. * Also, it looks like the [REST API endpoint](https://developer.wordpress.org/rest-api/) of the website is available at `/index.php?rest_route=/` which is unusual since it’s usually `/wp-json/`. See: [https://developer.wordpress.org/rest-api/key-concepts/#routes-endpoints](https://developer.wordpress.org/rest-api/key-concepts/#routes-endpoints) * Maybe Elementor is looking for it at the usual endpoint, idk. Try to go to Settings› Permalinks, choose a pretty permalink structure and hit _Save_.
