I am trying to containerize my Laravel project. I have the following services in my docker-compose.yml
laravel_app
database
nginx
phpmyadmin
All of them are running okay except PHPMyAdmin. It gets built and does serve the phpMyAdmin login page but I get the following errors when I enter the credentials.
Cannot log in to the MySQL server
mysqli::real_connect(): php_network_getaddresses: getaddrinfo failed: No address associated with hostname
mysqli::real_connect(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: No address associated with hostname
Here is my docker-compose.yml snippet that includes my database service and phpmyadmin service
#The Database
database:
container_name: mysql_database
image: mysql:5.7
volumes:
- dbdata:/var/lib/mysql
environment:
- "MYSQL_DATABASE=dev-db"
- "MYSQL_USER=phpmyadmin"
- "MYSQL_PASSWORD=phpmyadmin"
- "MYSQL_ROOT_PASSWORD=123456"
ports:
- 8991:3306
#PHPMyAdmin Service
phpmyadmin:
container_name: phpmyadmin
image: phpmyadmin/phpmyadmin
ports:
- "8992:80"
depends_on:
- database
environment:
- "PMA_HOST:database"
- "MYSQL_USER:phpmyadmin"
- "MYSQL_PASSWORD:phpmyadmin"
- "MYSQL_ROOT_PASSWORD:123456"
- "UPLOAD_LIMIT:3000000000"
# redis
cache:
image: redis:3.0-alpine
volumes:
dbdata:
For that to work, you need to at least create a bridge network and connect phpmyadmin and your db to it.
Something like this should work:
version: "3"
volumes:
dbdata:
networks:
backend:
driver: bridge
services:
database:
container_name: mysql_database
image: mysql:5.7
volumes:
- dbdata:/var/lib/mysql
environment:
- "MYSQL_DATABASE=dev-db"
- "MYSQL_USER=phpmyadmin"
- "MYSQL_PASSWORD=phpmyadmin"
- "MYSQL_ROOT_PASSWORD=123456"
ports:
- 8991:3306
networks:
- backend
phpmyadmin:
container_name: phpmyadmin
image: phpmyadmin/phpmyadmin
ports:
- "8992:80"
depends_on:
- database
environment:
- "PMA_HOST=database"
- "MYSQL_USER=phpmyadmin"
- "MYSQL_PASSWORD=phpmyadmin"
- "MYSQL_ROOT_PASSWORD=123456"
- "UPLOAD_LIMIT=3000000000"
networks:
- backend
Also I do not recommend exposing DB port
EDITED: Fixed docker-compose file
Like Fominykh Maxim mentioned, my error was caused by syntax error while assigning environment value at phpmyadmin service. I had used PMA_HOST:database instead of PMA_HOST=database

Hello :) here is my docker compose :
version: "3.8"
services:
web-server:
build: .
volumes:
- ./:/var/www/html/
ports:

phpmyadmin:

ports:
- "8001:80"
links:
- "db:db"
environment:
MYSQL_USERNAME: root
MYSQL_ROOT_PASSWORD: root
As you can see, when i go to phpmyadmin with http://localhost:8001/ i have :
PhpMyAdmin Dashboard
Doctrine Migation is installed in my project, so when i try :
./vendor/bin/doctrine-migrations status
Errors are :
In AbstractMySQLDriver.php line 112:
An exception occurred in driver: SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: nodename nor servname provided, or not known
In Exception.php line 18:

In PDOConnection.php line 39:
PDO::__construct(): php_network_getaddresses: getaddrinfo failed: nodename nor servname provided, or not known
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
version: "3.8"

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 think this error occurred because MySQL container has a password different from MYSQL_ROOT_PASSWORD which I wrote in the doctor-compose.yml.
But, i think there seems to be no problem with the setup, why is this error happening?
And if i did not set up MYSQL_ROOT_PASSWORD, what is the default password value generated by MySQL container?
I searched for days to find the answer to this problem, but I could not get the answer. please give me some advices. thank you
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.
I've got this working now with the following:

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
According to the docker compose yaml,

it produces an error:

when logging in to phpMyadmin (http://127.0.0.1:8080).
I have tried to fix this problem, but nothing works.
Could you please find a solution?
Any recommendations/comments are welcomed here.
I had a similar problem try this in the links directive - container-name:db as below
links:
- mariadb:db
you should links your phpmyadmin to database services in order to use the db service
pma:
image: phpmyadmin/phpmyadmin
links:
- db
container_name: phpmyadmin
restart: always
ports:
- "8080:80"
environment:
- PMA_HOST: maria_db
here is more about docker compose services links
If you set the following environment variable in docker compose:
pma:
environment:
- PMA_ARBITRARY=1
then you will be given the opportunity to enter the host server manually on the login screen. Enter the name of the database service there. In your case the name of the service is db

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.
