GitLab CI: мое тестовое задание не принимает контейнер mysql

У меня есть приложение springboot, которое связано с базой данных mysql. Я хочу использовать.gitlab-ci.yml для обработки конвейера. Я создал следующий файл конфигурации.

before_script:
 - echo "Execute scripts which are required to bootstrap the application. !"

after_script:
 - echo "Clean up activity can be done here !."

services:
 - mysql

stages:
 - build
 - connect
 - test
 - package
 - deploy

variables:
 MAVEN_CLI_OPTS: "--batch-mode"
 MAVEN_OPTS: "-Dmaven.repo.local=.m2/repository"
 MYSQL_DATABASE_NAME: gyyconsortiumdb
 MYSQL_DATABASE_SCHEMA: "$CI_PROJECT_DIR/src/main/resources/static/sql/gyyconsortiumdb.sql"
 MYSQL_ROOT_PASSWORD: mysql

cache:
 paths:
  - .m2/repository/
  - target/

build:
 stage: build
 image: maven:latest
 script:
  - mvn $MAVEN_CLI_OPTS clean compile

connect:
 stage: connect
 image: mysql
 before_script:
  - mysql --version
 script:
  - echo "create database $MYSQL_DATABASE_NAME;" | mysql --user=root --password="$MYSQL_ROOT_PASSWORD" --host=mysql
  - mysql --user=root --password="$MYSQL_ROOT_PASSWORD" --host=mysql $MYSQL_DATABASE_NAME < $MYSQL_DATABASE_SCHEMA
  - mysql --user=root --password="$MYSQL_ROOT_PASSWORD" --host=mysql -e "show databases; use $MYSQL_DATABASE_NAME; show tables;"

test:
 stage: test
 image: maven:latest
 script:
  - mvn $MAVEN_CLI_OPTS test

package:
 stage: package
 image: maven:latest
 script:
  - mvn $MAVEN_CLI_OPTS package
 artifacts:
  paths: [target/basecamp-0.0.1.war]


deploy_test:
 stage: deploy
 script:
 - echo "########   To be defined   ########"
 environment: staging

deploy_prod:
 stage: deploy
 script:
  - echo "########   To be defined   ########"
 only:
  - master
 environment: production

Когда выполняется первое задание, он вытаскивает изображение mysql из узла докеров, и я не знаю почему? Я думал, что mysql должен быть построен только на задании соединения.

Кроме того, после успешного выполнения задания на соединение тестовое задание снова вернет изображение mysql. И мое тестовое задание не распознает мою базу данных, однако служба была успешно создана, и я смог увидеть, что база данных также создана.

Не могли бы вы рассказать мне, почему тестовое задание не правильно подбирает службу mysql?
