我使用docker compose运行mysql和api服务器。一旦api服务器在上面，就使用connecttomysql，但我总是被拒绝访问。我已经添加了sql来授予权限，但它仍然不起作用。请有人帮帮我。
错误

2018-05-03T05:48:45.868146Z 2 [Note] Access denied for user 'mysql'@'172.18.0.3' (using password: YES)

这是我的 Docker

version: "3.6"
services:
  mysql:
    build:
      context: ..
      dockerfile: docker/Dockerfile-mysql
    image: test_mysql:ci-label

    labels:
      - "CI-TEST=ci-label"

networks:
  ci-network:
    labels:
      - "CI-TEST=ci-label"
    name: ci-network

这是我的dockerfile mysql

FROM mysql:5.7
LABEL CI-TEST="ci-label"
ENV MYSQL_ALLOW_EMPTY_PASSWORD=yes
    MYSQL_USER=mysql \
    MYSQL_PASSWORD=test
COPY init.sql docker-entrypoint-initdb.d/01.sql

这里是init.sql
