cannot connect to laradock mysql container via phpmyadmin

I have cloned laradock inside my laravel application. Now, I am trying to set my environment up and running. I have built images for nginx, mysql, mariadb, phpmyadmin and etc. Now, my problem is with mysql (and actuallly mariadb, too).
When I boot up phpmyadmin at localhost:8080 and try to connect to mysql from there I get these two similar error messages:

mysqli_real_connect(): php_network_getaddresses: getaddrinfo failed:
Name or service not known mysqli_real_connect(): (HY000/2002):
php_network_getaddresses: getaddrinfo failed: Name or service not
known

I have tried different configurations to resolve this. Currently my laradock .env file is like

MYSQL_VERSION=5.7
MYSQL_DATABASE=default
MYSQL_USER=default
MYSQL_PASSWORD=secret 
MYSQL_PORT=3306
MYSQL_ROOT_PASSWORD=root
MYSQL_ENTRYPOINT_INITDB=./mysql/docker-entrypoint-initdb.d

And the .env file of my laravel application is like

DB_CONNECTION=mysql
DB_HOST=mysql
DB_PORT=3306
DB_DATABASE=default
DB_USERNAME=default
DB_PASSWORD=secret

My laradock/mysql/Dockerfile is like

ARG MYSQL_VERSION=5.7
FROM mysql:${MYSQL_VERSION}
LABEL maintainer="Mahmoud Zalt <[email protected]>"
ARG TZ=UTC
ENV TZ ${TZ}
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > 
/etc/timezone && chown -R mysql:root /var/lib/mysql/
COPY my.cnf /etc/mysql/conf.d/my.cnf
CMD ["mysqld"]
EXPOSE 3306

My docker-compose.yml is like

 ### MySQL ################################################
    mysql:
      build:
        context: ./mysql
        args:
          - MYSQL_VERSION=${MYSQL_VERSION}
      environment:
        - MYSQL_DATABASE=${MYSQL_DATABASE}
        - MYSQL_USER=${MYSQL_USER}
        - MYSQL_PASSWORD=${MYSQL_PASSWORD}
        - MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD}
        - TZ=${WORKSPACE_TIMEZONE}
      volumes:
        - ${DATA_PATH_HOST}/mysql:/var/lib/mysql
        - ${MYSQL_ENTRYPOINT_INITDB}:/docker-entrypoint-initdb.d
      ports:
        - "${MYSQL_PORT}:3306"
      networks:
        - backend

I am using mysql 5.7 to avoid authentication method problem issue. I have run this to build mysql:

docker-compose build --no-cache mysql

And my mysql container cannot be up and mysql logs is like

    After a lot of struggling I realized that when downgrading from mysql 8 to a lower version, clearing the contents of data folder fixes the mysql container issue.

    cd ~/.laradock/data/mysql
sudo rm -rf *

    Do not try this if you have a database full of important data! Since you will lose all your data.

    In mysql host you have to provide the name of the service you used for your docker compose file:

    For example:
    If your docker-compose file is this:-
    version: “3”

    services:
  example-service-name:
    container_name: dzangohq-api
    image: your/image

    As you can see above the service name is example service name which you have to add in mysql host like this assuming you have exposed 3306 port:

    DB_CONNECTION=mysql
DB_HOST=example-service-name
DB_PORT=3306
DB_DATABASE=default
DB_USERNAME=default
DB_PASSWORD=secret

    In my my.cnf I have:

    # The MySQL  Client configuration file.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html

[mysql]

[mysqld]
sql-mode="STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION"
character-set-server=utf8

    then in my DockerFile i have:

    ARG MYSQL_VERSION=latest
FROM mysql:${MYSQL_VERSION}

LABEL maintainer="Mahmoud Zalt <[email protected]>"

#####################################
# Set Timezone
#####################################

ARG TZ=UTC
ENV TZ ${TZ}
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone && chown -R mysql:root /var/lib/mysql/

COPY my.cnf /etc/mysql/conf.d/my.cnf

CMD ["mysqld"]

EXPOSE 3306

    In docker-compose.yml

    ### MySQL ################################################
    mysql:
      build:
        context: ./mysql
        args:
          - MYSQL_VERSION=${MYSQL_VERSION}
      environment:
        - MYSQL_DATABASE=${MYSQL_DATABASE}
        - MYSQL_USER=${MYSQL_USER}
        - MYSQL_PASSWORD=${MYSQL_PASSWORD}
        - MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD}
        - TZ=${WORKSPACE_TIMEZONE}
      volumes:
        - ${DATA_PATH_HOST}/mysql:/var/lib/mysql
        - ${MYSQL_ENTRYPOINT_INITDB}:/docker-entrypoint-initdb.d
      ports:
        - "${MYSQL_PORT}:3306"
      networks:
        - backend

    And in .env set 5.7 mysql version.

    Try with this configuration, for me it works, if not work try to see this post on github:

    https://github.com/laradock/laradock/issues/1350

    Could be the problem with volume.
