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:
- 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: {}
and ran the command docker stack deploy -c docker-compose.yml mysqllab
This is the result

I have the following docker-compose file.

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:
version: '3.8'
services:
mysql:
image: mysql:5.7
container_name: myapp-mysql-db
restart: unless-stopped
ports:
- "3306:3306"
environment:
MYSQL_DATABASE: ${DB_DATABASE}
MYSQL_ROOT_PASSWORD: ${DB_PASSWORD}
MYSQL_PASSWORD: ${DB_PASSWORD}
MYSQL_USER: ${DB_USERNAME}
volumes:
- ./database/dbdata:/var/lib/mysql
networks:
- myapp-network
phpmyadmin:
image: phpmyadmin:latest
container_name: phpmyadmin
ports:
# 8080 is the host port and 80 is the docker port
- 8080:80
environment:
PMA_HOST: mysql
UPLOAD_LIMIT: 20M
MYSQL_USERNAME: ${DB_USERNAME}
MYSQL_ROOT_PASSWORD: ${DB_PASSWORD}
restart: unless-stopped
networks:
# define your network where all containers are connected to each other

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
ports:

MYSQL_DATABASE: app
PMA_HOST: mariadb
depends_on:

networks:

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:
- '8081:80'
networks:
- laravel
I have setup docker-compose to run phpmyadmin and mysql. Here is my docker-compose.yml
version: "3.9"
networks:
local_web_network:
driver: bridge
volumes:
mysql_data:

PMA_ABSOLUTE_URI: http://db.test
MYSQL_ROOT_PASSWORD: secret
networks:
- local_web_network
extra_hosts:
- 'db.test:127.0.0.1'
I have configured the windows hosts file with the below settings
127.0.0.1 db.test
I have successfully run the docker containers without any errors. I have tried accessing the http://127.0.0.1:8083 or http://db.test:8083 it works and displays the phpmyadmin login page.
But the problem here is, i am unable to access the page without specifying the port i.e http://db.test. How do i get this working without specifying the port?
I'm trying to reproduce a MAMP environment with Docker-Compose, but I can't connect the phpmyadmin service to my mariaDB database!
I have done a lot of testing, and nothing has been conclusive, at best phpmyadmin does not recognize user and password and I get the following message:
mysqli_real_connect(): (HY000/1045): Access denied for user 'root'#'172.25.0.3' (using password: YES)
Here is the docker-compose file:

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:

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:

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
