I run docker-compose up -d and everything works fine, but I can not access to the mariadb server from host, I tried these
# mysql -uroot -p
Enter password:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
# mysql -uroot -p -h mariadb
Enter password:
ERROR 2005 (HY000): Unknown MySQL server host 'mariadb' (-2)
# mysql -uroot -p -h 127.0.0.1
Enter password:
ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1:3306' (111)
Edit:
.env file:
MYSQL_ROOT_PASSWORD=abc1234
MYSQL_DATABASE=my_db
MYSQL_USER=drupal
MYSQL_PASSWORD=cdf1234
From MariaDB Docker Library documentation;
One of MARIADB_ROOT_PASSWORD, MARIADB_ALLOW_EMPTY_ROOT_PASSWORD, or
MARIADB_RANDOM_ROOT_PASSWORD (or equivalents, including *_FILE), is
required. The other environment variables are optional.
This is for the initialization of the db-data volume. Once initialized, these environment variables are optional.

I want to run two docker container, one for phpmyadmin and one for mysql server, so i wrote this docker-compose file to run it on RaspberryPi:
version: '3.1'
services:
db:
image: mysql:latest
container_name: db
volumes:
- dbdata:/var/lib/mysql
restart: always
ports:
- 3306:3306
environment:
MYSQL_ROOT_PASSWORD: test
phpmyadmin:
image: phpmyadmin
container_name: phpmyadmin
restart: always
ports:
- 8080:80
environment:
PMA_HOST: db
PMA_ARBITRARY: 1
volumes:
dbdata:
The volume mount, the containers build up, the phpmyadmin page load but when i try to login with server: machine-ip:3306, user: root, pass: test; got this error:
mysqli::real_connect(): Error while reading greeting packet. PID=34
mysqli::real_connect(): (HY000/2006): MySQL server has gone away
Tried everything and worked only one time, but when i restarted it not worked again
I have been trying to setup docker-compose for my application written in flask and connect it to msql database. Both containers are seems to be working fine and aplication starts properrly, but whenever there is any request to database, I am getting following error from my flask-app comtainer:
sqlalchemy.exc.OperationalError: (MySQLdb.OperationalError) (2002, "Can't connect to local MySQL server through socket '/run/mysqld/mysqld.sock' (2)")
For me it looks like my containers don't see each other. I am new to Docker, but I thought that my current docker-compose should work
version: '3.9'

backend:
volumes:
mysqldb:

flask-app logs
Also I have been trying to connect to mysql-db container from flask-app container with command mysql --host localhost --port 3306 -u user -p but still getting the same error.
My Docker knowledge is very limited but should I have msql server installed also on flask-app?
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)

I'm trying to connect to my mysql database using official adminer and mysql images from docker hub.
Here is my docker-compose.yml file configuration:
version: '3'
services:
mysql:
image: mysql
restart: always
volumes:
- mysql:/var/lib/mysql
environment:
- MYSQL_ALLOW_EMPTY_PASSWORD= 1
- MYSQL_DATABASE= db
ports:
- 3306:3306
- 33060:33060
adminer:
image: adminer
restart: always
ports:
- 8080:8080
depends_on:
- mysql
volumes:
mysql:
Whenever I want to login to the MySQL using Adminer I face with the following problem:
SQLSTATE[HY000] [2054] The server requested authentication method unknown to the client
SQLSTATE[HY000] [2002] No such file or directory
Here is the inputs I've used trying to connect to MySQL from Adminer interface:
#first try
System: MySQL
Server: localhost
Username: root
Database: db
#second try
System: MySQL
Server: mysql #container-name
Username: root
Database: db
You have to add the default authentication plugin in compose file
command: --default-authentication-plugin=mysql_native_password
Here is the complete docker-compose.yml
services:
mysql:
image: mysql
restart: always
command: --default-authentication-plugin=mysql_native_password
volumes:
- mysql:/var/lib/mysql
environment:
- MYSQL_ALLOW_EMPTY_PASSWORD= 1
- MYSQL_DATABASE= db
ports:
- 3306:3306
- 33060:33060
adminer:
image: adminer
restart: always
ports:
- 8080:8080
depends_on:
- mysql
volumes:
mysql:
In adminer
System: MySQL <DB System to connect>
Server: mysql <should match the starting tag before image tag > (in your case mysql but you can change it to any name )
Username: root <username>
Password: <password>
Database: db <database name>
Before, I created named volume and database: 'mysql-db1' using other mysql container.
I can't connect to database from python.
My .yml file :
version: '3.6'
services:
python:
image: python:latest
ports:
- '80:80'
volumes:
- type: bind
source: .
target: /scripts
command: tail -f /dev/null
links:
- 'mysql'
mysql:
image: mysql/mysql-server:latest
ports:
- '3306:3306'
environment:
MYSQL_ROOT_PASSWORD: root
volumes:
- type: volume
source: mysql-db1
target: /var/lib/mysql
volumes:
mysql-db1:
external: true
My simply python code:
import mysql.connector
cnx = mysql.connector.connect(user='root', password='root', host='mysql', database='test1')
cnx.close()
I can enter the database using:
$ docker-compose exec mysql bash
# mysql -uroot -proot -Dtest1
Error:
mysql.connector.errors.DatabaseError: 1130 (HY000): Host '172.18.0.3' is not allowed to connect to this MySQL server
Where is a problem?
root user is not allowed to access the db externally by default. Use image environment variables to create a user and use that:
db:
restart: always
image: mariadb
container_name: myapp_db
environment:
- MYSQL_USER=myuser
- MYSQL_PASSWORD=mypass
- MYSQL_DATABASE=mydb
- MYSQL_ALLOW_EMPTY_PASSWORD=yes
ports:
- 3306:3306
