Answer 1

Your connection actually works and you can verify it running the following (service should be running already:):

docker-compose exec db sh -c 'mysql -uroot -p${MYSQL_ROOT_PASSWORD}'

The problem is that you are using the wrong password.

You can see your problem very easily by running docker-compose config . You will see in the output that the double quotes are included as part of the values.

This version should solve your issue:

version: '3.3'

services:
   db:
    image: mysql:5.7.29
    container_name: mysql
    deploy:
      replicas: 1
      restart_policy:
        condition: on-failure
    environment:
      - MYSQL_USER=testpass
      - MYSQL_PASSWORD=testpass
      - MYSQL_ROOT_PASSWORD=testpass
    ports:
      - 33060:3306
    volumes:
      - /Users/hello/Work/Volumes/wavolumes/mysql:/var/lib/mysql

Answer 2

Stumbled upon the same error and tried the accepted solution, along with just using a Dockerfile, trying the "MYSQL_ALLOW_EMPTY_PASSWORD", the "MYSQL_RANDOM_ROOT_PASSWORD" and different mysql image tags (5.6, 5.7 and latest). Root creds are also not working. I'm clearly doing something wrong.

My compose looks like this:

version: '3.3'
services:
  db:
    image: mysql:5.7
    restart: always
    environment:
      MYSQL_USER: usr
      MYSQL_PASSWORD: pass
      MYSQL_ROOT_PASSWORD: root
    ports:
      - "3306:3306"
    volumes:
      - d:/vm/docker-volumes/mysql:/var/lib/mysql

I build it through docker-compose -f "docker-compose.yml" up -d --build command, and then try to connect to it by doing docker exec -it docker_db_1 bash -c 'mysql --protocol=tcp -u usr -p${MYSQL_PASSWORD}' and other variants. Allways get the ERROR 1045 (28000): Access denid for user...

Would you mind clarifying if you've done something else to make it work, apart from the suggested steps in the accepted answer?
