我已经使用JHipster创建了一个微服务，并且在将数据源设置保留为没有root密码的默认设置时一切正常。服务以docker-compose up -d启动并按预期工作。
但是我想为生产中的不同微服务更改数据库root密码，所以为了做到这一点，我的理解是我必须：
microservice1-mariadb:
image: 'mariadb:10.3.7'
environment:
- MYSQL_USER=root
- MYSQL_ROOT_PASSWORD=secretPassword
- MYSQL_ALLOW_EMPTY_PASSWORD=no
- MYSQL_DATABASE=microservice1
command: mysqld --lower_case_table_names=1 --skip-ssl --character_set_server=utf8mb4 --explicit_defaults_for_timestamp
spring:
...
datasource:
type: com.zaxxer.hikari.HikariDataSource
url: jdbc:mariadb://localhost:3306/microservice1?useLegacyDatetimeCode=false&serverTimezone=UTC
username: root
password: secretPassword
要手动测试与数据库的连接，我连接到microservice1容器并连接
mysql -u root -h microservice1-mariadb -p
并提供secretPassword。这按预期工作。
但是启动'microservice1'容器会抛出异常：

我很难理解我错过了哪一部分？
确实问题与我对码头工作者缺乏了解有关，以及当码头工人更新图像，容器和卷时。重新创建数据库容器后，所有操作都按预期工作。
