无法在位桶管道上连接到MySQL（111“连接被拒绝”）

Question

I try to connect to a database in my bitbucket pipeline and use the service definition as described in the docs , but I get the following error:

+ mysql -h 127.0.0.1 -u root -ptest_user_password -e "SHOW DATABASES"
ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1' (111 "Connection refused")

Here's my bitbucket-pipelines.yaml :

image: debian:stretch

pipelines:
  pull-requests:
    '*':
      - step:
          script:
            - apt-get update && apt-get install -y mysql-client
            - mysql -h 127.0.0.1 -u root -ptest_user_password -e "SHOW DATABASES"
definitions:
  services:
    mysql:
      image: mysql:5.7
      variables:
        MYSQL_DATABASE: 'pipelines'
        MYSQL_ROOT_PASSWORD: 'test_user_password'

Any ideas what I am doing wrong?

You forgot to tell your service to actually use the mysql service. Try that config:

image: debian:stretch

pipelines:
  pull-requests:
    '*':
      - step:
          script:
            - apt-get update && apt-get install -y mysql-client
            - mysql -h 127.0.0.1 -u root -ptest_user_password -e "SHOW DATABASES"
          services:
            - mysql
definitions:
  services:
    mysql:
      image: mysql:5.7
      variables:
        MYSQL_DATABASE: 'pipelines'
        MYSQL_ROOT_PASSWORD: 'test_user_password'
