On Windows 10 Home edition (so using docker-toolbox) I also ran into this problem.
It seems that the wordpress image now required the environment setting:
WORDPRESS_DB_HOST: db:3306.
After adding this, the wordpress container can connect to the database.
Also with Windows 10 Home edition I can't get the port mapping to work for localhost. I need to lookup the ip-adress via docker-machine ip and connect to the port there.
On Linux Mint (based on Ubuntu) this does not seem required.
So I expect this to be an installation problem with docker-toolbox or Windows 10 Home Edition.

My problem Is that when I try to login with phpmyadmin I get the following error:
mysqli::real_connect(): php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution
And also
mysqli::real_connect(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution
Is there something I'm missing?
networks:
- webnet
add webnet network to phpmyadmin service
There are more options to solve the connection.
Add phpmyadmin container to webnet network as Def Soudani suggests. The YML example provided overrides the default network. Since the phpMyAdmin is lacking the network config, it won't be on the webnet docker network by default.
Remove all networks related config from the YML. Since compose already creates a default network (docs) for the containers within one YML file.
Use the PMA_ARBITRARY=1 (docs )which allows you to enter a database server hostname on login form.
Example of my YML setup with custom bridge networking:

As you can see, when i go to phpmyadmin with http://localhost:8001/ i have :

Doctrine Migation is installed in my project, so when i try :
./vendor/bin/doctrine-migrations status
Errors are :

Connexion in my env file is :
BDD = pdo-mysql://root:root#db:3306/playlist_maker_multi
I expose port 3306 on my docker-compose so i don't understand why outside my container i can't access to my Database ?
Thanks everybody, if you have explanations.
Have a nice day.

Could you try running it with this config
I renamed the db service to mysql, explicitly added a network and made your php service depend on mysql, so it will restart untill it establishes a connection, just in case the php container starts running before the mysql container

For applications running on your host machine but outside of your Docker network (i.e. not containerised) that need to connect to a container, you can use localhost instead of db, as the DNS name db is only valid inside the Docker Compose network.
With:
mysql:
image: mysql:5.6
container_name: db
ports:
- "3306:3306"
you are creating a path from locahost:3306 (or MACHINEIP:3306 if on another machine) to the service on mysql:3306 inside the network.
#clarj, do you mean like that ?

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:
version: '3'
services:

build: .docker/apache

maildev:

container_name: sf4_maildev
ports:
- 8001:80
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 have a docker compose file which is basically trying to build a WAMP/LAMP style environment.
Basically, PHPMyAdmin can't seem to connect to MySQL. Looking through answers here, it appeared that it was an issue with legacy auth using MySQL Image 8 so I added:
command: --default-authentication-plugin=mysql_native_password
but that didn't work, so I dropped down to mysql image5.7 and the issue is still present. For some reason, I can't connect to MySQL and I get the error:
mysqli_real_connect(): php_network_getaddresses: getaddrinfo failed: Try again
and
mysqli_real_connect(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: Try again
Here is a copy of my Docker Compose which I don't think is doing anything weird.
Hoping someone can clarify that for me.

I also saw mention of a "depends on" flag which I tried too but that also failed to allow me to connect. I have had the same error throughout.
It's about the container name.
database:
image: mysql:5.7.25
ports:
- "3306:3306"
- **container_name: db-mysql**
and in your phpcontainer:
phpmyadmin:
build:
context: .
dockerfile: PHPMYADMIN.Dockerfile
restart: always
links:
- database:mysql
environment:
**PMA_HOST: mysql**
PMA_PORT: 3306
you define host as mysql, which in docker network will be unrecognizable.
try switching PMA_HOST to db-mysql.
Sorry for bad formatting.
Also use docker ps to see docker container names and to figure out which hosts do you need to connect.

According to your phpmyadmin service configuration, you are trying to reach mysql container by mysql address:
environment:
PMA_HOST: mysql
PMA_PORT: 3306
But container with mysql server is accessible by database or db-mysql addresses.
So, you need to change phpmyadmin service configuration to:
environment:
PMA_HOST: database
PMA_PORT: 3306
I am trying to set up a docker container for WordPress development using docker-compose.yml which looks like this:

I tried clearing my images and containers but no luck. Any idea why this happens?
Try providing links option for both wordpress and phpmyadmin.
links:
- db:mysql
Edit: Check this question. Add mysql to the db. I don't if this solves, I have to try out once I go home later.
