Docker Wordpress 站点中的 URL 问题

Question

I wanted to create a local dev environment for a wordpress site using docker. So I have the following docker-compose file :

version: '3'

services:
  db:
    image: mariadb
    restart: on-failure
    environment:
    - MYSQL_DATABASE=${WP_DB_NAME}
    - MYSQL_USER=${WP_DB_USER}
    - MYSQL_PASSWORD=${WP_DB_USER_PASSWORD}
    volumes:
    #- ./db_data:/var/lib/mysql
    - ./mysql_dump/backup.sql:/docker-entrypoint-initdb.d/backup.sql
    - ./mysql_dump/migrate.sql:/docker-entrypoint-initdb.d/migrate.sql
    networks:
    - local

  wordpress:
    image: wordpress
    depends_on:
    - db
    restart: always
    ports:
      - 8080:80
    environment:
    - WORDPRESS_DB_HOST=db
    - WORDPRESS_DB_USER=${WP_DB_USER}
    - WORDPRESS_DB_PASSWORD=${WP_DB_USER_PASSWORD}
    - WORDPRESS_DB_NAME=${WP_DB_NAME}
    volumes: 
    - ./htdocs:/var/www/html
    networks:
      local:
        ipv4_address: 172.23.0.4

networks:
  local:
    driver: bridge
    ipam:
      config:
      - subnet: 172.23.0.0/24

I use volume to start mariadb with existing database dump.

Website is loading fine, but some URLs are wrong :

• When I try to connect, I am redirected to : http://172.23.0.4/172.23.0.4/wp-admin/ for example
• Some js scripts are also not loaded due to wrong URLs like http://172.23.0.4172.23.0.4/wp-includes/js/tinymce/tinymce.min.js?ver=4920-20181217

I checked the general settings in the admin panel, and the values siteurl and home in the database and they are correct : 172.23.0.4 . The website in production (no docker but classic LAMP install) is working fine by the way…

Do you have any hints ? (I'm not that familiar with web development, especially with wordpress)

Answer 1

Looks like specifying 172.23.0.4 in wordpress settings for home and siteurl is somehow (don't know why though) causing the issue. Instead, setting the value to http://172.23.0.4 fixed the problem.

If someone has some explanation, please tell me.
