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'

environment:

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

depends_on:

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.

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:

build: .conf/php/
restart: always

mariadb-volume:
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:

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'm trying to user docker-compose for mysql and phpmyadmin, but I'm getting an authentication error when trying to log in to phpmyadmin.
I've tried several configurations on the yaml file, but without any success.
version: '3'
services:
db:
image: mysql
command: --default-authentication-plugin=mysql_native_password
restart: always
environment:
MYSQL_DATABASE: mydb
MYSQL_USER: root
MYSQL_PASSWORD: admin
MYSQL_ROOT_PASSWORD: admin
volumes:
- my-db:/var/lib/mysql
phpmyadmin:
image: phpmyadmin/phpmyadmin:latest
links:
- db
ports:
- 8080:80
restart: always
environment:
PMA_USER: root
PMA_PASSWORD: admin
volumes:
my-db: {}
When I try logging in to phpmyadmin i get the following errors:
mysqli_real_connect(): The server requested authentication method unknown to the client [caching_sha2_password]
mysqli_real_connect(): (HY000/2054): The server requested authentication method unknown to the client
I tried to change the yml to:
version: '3'
services:
db:
image: mysql:57
restart: always
environment:
After this, the container no longer starts, and it gives the following message:
docker_db_1 exited with code 1
This works fine:
version: '3'
services:
db:
image: mysql:5.7
command: --default-authentication-plugin=mysql_native_password
restart: always
environment:
MYSQL_DATABASE: mydb
MYSQL_USER: root
MYSQL_PASSWORD: admin
MYSQL_ROOT_PASSWORD: admin
volumes:
- my-db:/var/lib/mysql
phpmyadmin:
image: phpmyadmin/phpmyadmin:latest
links:
- db
ports:
- 8080:80
restart: always
environment:
PMA_USER: root
PMA_PASSWORD: admin
volumes:
my-db: {}
Remember to delete the volume before running (in case you run into issues).
I just copied this code in docker-compose.yml
version: '3'
services:
db:
image: mysql
command: --default-authentication-plugin=mysql_native_password
restart: always
environment:
MYSQL_DATABASE: mydb
MYSQL_USER: root
MYSQL_PASSWORD: admin
MYSQL_ROOT_PASSWORD: admin
volumes:

phpmyadmin:
image: phpmyadmin/phpmyadmin:latest
links:
- db
ports:
- 8080:80
restart: always
environment:
PMA_USER: root
PMA_PASSWORD: admin
volumes:
my-db: {}
and ran the command docker stack deploy -c docker-compose.yml mysqllab
This is the result

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
I'm learning to use docker to make my development easier but I'm still failing access mysql.
Here is my docker-compose.yaml:
version: '3.3'
services:
# Database
db:
image: mysql:latest
ports:
- '3306:3306'
volumes:
- db_data:/var/lib/mysql

MYSQL_DATABASE: dev1
MYSQL_USER: root
MYSQL_PASSWORD: password

Wordpress is running without difficulties which means that mysql must be alright too. I'm on Linux and trying to connect database via mysql workbench. It appears that connection is also ok expect for, there is no schema and so no wordpress tables.
I tried to add also phpmyadmin into docker-compose.yaml:
phpmyadmin:
depends_on:
- db
image: phpmyadmin/phpmyadmin
restart: always
ports:
- '8080:80'
environment:
PMA_HOST: db
MYSQL_ROOT_PASSWORD: password
networks:
- wpsite
but here I get following error after attempt to access db:
What I miss?
EDIT:
here is overview of running containers:
So i modified your docker-compose , with 2 small changes , and i dont have a issue .
I created a user for wordpress ( userdev1 ) in mysql .
The root is already here and can have some restrictions for remote access .
Via phpmyadmin i can login with userdev1 or root
You want a network access with the root account you must set this variable
MYSQL_ROOT_HOST .

** UPDATED **
With the very last version of mysql docker image ( aka mysql 8.0 ),
you must change the default-authentification to mysql_native_password to be comptatible with legacy mysql client
