Why does mariadb throw an error: Packets out of order. Expected 0 received 1. Packet size=69?

  mariadb:
    driver: ${VOLUMES_DRIVER}

networks:
  frontend:
    driver: ${NETWORKS_DRIVER}
  backend:
    driver: ${NETWORKS_DRIVER}

I'm running only maridb and phpmyadmin so far. I go to localhost: 8080, enter any user and any password into the mariadb host, I get an error:

Answer 1

In general, the problem was precisely in the absence of root for any host. I went into the container, then entered mysql: mysql -u root -pEnter the password, if any, and then

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password';
