wordpress docker compose (56) Recv failure: Connection reset by peer

I have this docker-compose file to set up a WordPress development environment. The challenge is everything runs correctly according to the logs, but the WordPress doesn’t load over the URL: localhost:9000 as specified.

I have tried changing the ports.

I am not sure what the issue could be. I need help.

docker log:

docker logs wordpress-app

    It appears that it may be the image you are using for WordPress.

    For example, I have tried your docker-compose file, switched out to the lastest WordPress, MySQL and phpmyadmin images, and I don’t have any issues with connectivity across them.

    Also make sure to delete the data, WordPress, wp-content directories that are placed in your directory as volumes.

    The problem you’re facing with your configuration is that image you’re using (wordpress:6.2.0-php8.2-fpm) only expose port 9000 as a FastCGI service, not as a HTTP service. You can’t make HTTP requests to it. That’s usual behaviour of PHP FPM images.

    You need to add a webserver ( apache or nginx ) container connected to FPM service to get HTTP responses.

    Try to add this to your configuration:

    nginx:
  image: 'nginx'
  restart: unless-stopped
  container_name: 'nginx'
  ports:
    - 80:80
    - 443:443
  volumes:
    - "./wordpress:/var/www/html"
  networks:
    - wp
