I am new to docker and i have this docker .yml file (below) and i have a local set up of my WordPress site, i have imported a sql dump into a database in the 'container_web'. The problem i am having is that when i try to connect WordPress to the database inside the container i get this error "Error establishing a database connection." For the host i've used localhost, 127.0.0.1, mysql and none of them seems to work.
Do you know or could direct me in the right direction on what i should be checking in order to connect my WordPress install to the database?

I am trying to build up a docker-compose file to run all components I need for my app. The app, mysql (mariadb) and phpmyadmin is running but I can't login to my database.
Following docker-compose.yml:
version: '3.7'
networks:
laravel:
services:
php:
image: php:7.4-fpm
build: .conf/php/
restart: always

When I try to login, I get the following error:
mysqli::real_connect(): (HY000/1045): Access denied for user 'admin'#'172.31.0.6' (using password: YES)
I tried to find a solution.. something like set up the right env vars for mysql or set up a bridge between mysql and phpmyadmin. I did the network bridge and I can't really see the problem with my env vars.
Any clue?
System: Windows 10
Edit:
Found the problem. I just did docker-compose down -v ( -v = Remove named volumes declared in the volumes section of the Compose file and anonymous volumes )
and it worked :)
May be you can set for phpmyadmin by this command:
phpmyadmin:
image: phpmyadmin:latest
container_name: pma
restart: always
environment:
MYSQL_DATABASE: app
PMA_HOST: mariadb
depends_on:
- mariadb
ports:
- '8081:80'

I’m trying to set up a local dev environment for WordPress with MySQL.
After starting the container, the WordPress element works fine and is accessible.
But MySQL throws connection refused despite being able to connect using the same database details in MySQL Workbench.
I have tried changing the host from dB:3306 to 0.0.0.0:3306 but to no avail.
Using Docker for Mac OS.

Does anybody have any ideas what’s going on here?
I'm creating a laravel project in a docker container, along with MySQL and phpmyadmin, when trying to migrate (or access the database from phpmyadmin) I get access denied error.
I've tried several SOF solutions but none of them worked, also tried ones in GitHub issues.
here is my docker-compose.yml
version: "3"
services:
web:
container_name: ${APP_NAME}_web
build:
context: ./docker/web
ports:
- 9000:80
volumes:
- ./:/var/www/app
networks:
- mynet
db:
image: mysql:5.7
container_name: db
command: --default-authentication-plugin=mysql_native_password
restart: always
ports:
- "3306:3306"
environment:
MYSQL_DATABASE: laracocodb
MYSQL_USER: root
MYSQL_PASSWORD: root
MYSQL_ROOT_PASSWORD: root
volumes:
- mysqldata:/var/lib/mysql/
networks:
- mynet
phpmyadmin:
image: phpmyadmin/phpmyadmin
container_name: phpma
links:
- db:db
ports:
- 9191:80
environment:
MYSQL_USERNAME: root
MYSQL_ROOT_PASSWORD: root
PMA_HOST: db
networks:
- mynet
networks:
mynet:
driver: bridge
volumes:
mysqldata:
driver: local
no matter where I access the database (from db container bash, from phpmyadmin index page or from the web service when trying to migrate the database), the error is always access denied
I have also run into this problem many times, by default MySQL allows root to be accessed by localhost user that means even if you have opened the port 3306:3306, you will still need to add the user.
Follow these commands and the error will resolve!

I am using this Docker config: https://github.com/romaricp/kit-starter-symfony-4-docker
I start the environment by using:
docker-compose build
followed by:
docker-compose up -d
Everything is running fine but there is a problem with MySQL service. I get an Symfony error:
"An exception occurred in driver: could not find driver"
as well as PMA error when I try to login to DB:
mysqli_real_connect(): php_network_getaddresses: getaddrinfo failed:
Name does not resolve
Any idea how could I make it work?
docker-compose.yml:

Also I opened the mysql logs and I see this:
2019-04-07T12:00:30.943414Z 0 [System] [MY-010931] [Server] /usr/sbin/mysqld: ready for connections. Version: '8.0.15' socket: '/var/run/mysqld/mysqld.sock' port: 3306 MySQL Community Server - GPL.
Maybe the port is wrong and that's why I can't connect?
For phpmyadmin service, i think you should set the PMA_HOST and PMA_PORT environment variables like this:
phpmyadmin:
image: phpmyadmin/phpmyadmin
container_name: sf4_phpmyadmin
environment:
PMA_HOST: mysql
PMA_PORT: 3306
ports:
- 8080:80
links:
- mysql
Your mysql container should have the command instruction at the start to set the authentication plugin (there is an issue with the connectors with mysql 8), more details here
mysql:
image: mysql
container_name: sf4_mysql
command: "--default-authentication-plugin=mysql_native_password"
volumes:
- .docker/data/db:/var/lib/mysql
environment:
MYSQL_ROOT_PASSWORD: root
MYSQL_DATABASE: sf4
MYSQL_USER: sf4
MYSQL_PASSWORD: sf4
in your Symfony app, the connection string is located in .env file, and it should have the following format :
DATABASE_URL=mysql://mysql_user:mysql_user_password#mysql_host:mysql_port/db_name
mysql_user: your mysql user (ex: root)
mysql_user_password: the user's password (ex: root)
mysql_host: is should contain your mysql container service name
located in your docker-compose.yml file (mysql in this case)
mysql_port: mysql container internal port (3306, in this case)
db_name: the database you want to connect to.
the DATABASE_URL can look like this :
DATABASE_URL=mysql://root:root#mysql:3306/sf4
stop your containers after these changes and start them up again.
Hope this will help.
You have to expose the mysql port 3306:
mysql:
image: mysql
container_name: sf4_mysql
volumes:
- .docker/data/db:/var/lib/mysql
restart: always
ports:
- "3306:3306"
environment:
MYSQL_ROOT_PASSWORD: root
MYSQL_DATABASE: sf4
MYSQL_USER: sf4
MYSQL_PASSWORD: sf4
networks:
- default
I think you're having trouble linking the containers. I suggest that you use a custom network instead of linking. That all containers can see each other
Not sure what I am doing wrong but my wordpress docker just does not connect to the mysql docker. Can someone help me here please?
version: '2'
services:
db:
image: mysql:8.0
container_name: eve_db
volumes:
- ./database/data:/var/lib/mysql
- ./database/initdb.d:/docker-entrypoint-initdb.d
restart: always
environment:
MYSQL_ROOT_PASSWORD: skdjd # any random string will do
MYSQL_DATABASE: djdjd # the name of your mysql database
MYSQL_USER: djdjd # the name of the database user
MYSQL_PASSWORD: djdjd # the password of the mysql user
wordpress:
depends_on:
- db
image: wordpress:php7.2 # we're using the image with php7.1
container_name: eve_de
ports:
- "8080:80"
restart: always
links:
- db:mysql
volumes:
- ./src/wp:/var/www/html
I have also defined
define('DB_HOST', 'db:3306');
in the wp-config.php file. But it did not work.
The main site was having mysql v5.6.38. Changing the same in docker-compose.yml solved the issue.
