Hi :slight_smile:

At the wordpress installer, what do you type in as a database hostname?

also, in your wordpress “networks” attr, you typed in:

networks:
local:

should be:

networks:
- local

also, try and rename/alias your mariadb container to “mysql”, or add the env:

WORDPRESS_DB_HOST: mariadb

to your wordpress container

If I change “local:” to “- local” : ERROR: yaml.parser.ParserError: while parsing a block collection
in “./docker-compose.yml”, line 11, column 7

With “WORDPRESS_DB_HOST: mariadb” problem resolved.

THX :slight_smile:

Hello, i have a really similare issues but a little bit different so i cannot fix it.
I have one container with nginx, one with wordpress and php-fpm and a last one with mariadb.
when i try this command line :./wp-cli.phar config create --dbname=db_wordpress --dbuser=buakaw --dbpass=buakaw --dbhost=mariadb --path=/var/www/html/ --allow-root --force
i have this error :
PHP Warning: mysqli_real_connect(): php_network_getaddresses: getaddrinfo failed: Name or service not known in phar:///var/www/html/wp-cli.phar/vendor/wp-cli/config-command/src/Config_Command.php on line 234

here’s my docker compose file :

services:
  nginx:
    build: ./requirements/nginx/.
    container_name: nginx
    ports:
      - 443:443
    restart: always
    networks:
      - inception
    volumes:
      - ./web:/var/www/html
  wordpress:
    depends_on:
      - mariadb
    build: ./requirements/wordpress/.
    container_name: wordpress
    expose:
      - "9000"
    restart: always
    networks:
      - inception
    volumes:
      - ./web:/var/www/html/
    environment:
      - WP_HOST=mariadb
      - WP_DB_USER=buakaw
      - WP_DB_PASSWORD=buakaw
      - WP_DB_NAME=db_wordpress
  mariadb:
    build: ./requirements/mariadb/.
    container_name: mariadb
    ports:
      - "3306"
    restart: always
    networks:
      - inception
    volumes:
      - ./web:/var/www/html/
    environment:
      - MYSQL_ROOT_PASSWORD=buakaw
      - MYSQL_USER=buakaw
      - MYSQL_PASSWORD=buakaw
      - MYSQL_DATABASE=db_wordpress
networks:
  inception:
    driver: bridge

and here the script i lunch to config the wordpress database:

#!/bin/bash

mkdir -p /var/www/html
cd /var/www/html
curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar -P /var/www/
chmod +x wp-cli.phar
./wp-cli.phar core download --allow-root
./wp-cli.phar config create --dbname=db_wordpress --dbuser=buakaw --dbpass=buakaw --dbhost=mariadb --path=/var/www/html/ --allow-root --force
./wp-cli.phar core install --url=${WP_HOME_URL}--title=${WP_BLOG_TITLE} --admin_user=${WP_ADMIN_USER} --admin_password=${WP_ADMIN_PASS} --admin_email=${WP_ADMIN_EMAIL} --allow-root
