Flyway 无法从 Docker-Container 连接到 MySQL

Posted 2023-02-26

【中文标题】Flyway 无法从 Docker-Container 连接到 MySQL

【英文标题】：Flyway cannot connect to MySQL from Docker-Container

【发布时间】：2019-09-28 03:45:59

【问题描述】：

Flyway 尝试连接到 mysql Docker-Container。 Flyway 集成在 Spring Boot 项目中。 Spring Boot Project 和数据库都是从 docker-compose 开始的。

无法将数据库客户端连接到数据库容器。

在Flyway的错误日志中，有消息：

Access denied for user 'root'@'172.19.0.3' (using password: NO)

我尝试使用 *** 的几种解决方案来解决这个问题。 我试图更改 application.properties 文件。 还尝试使用 init.sql 创建一个新用户。 使用 docker-compose，我尝试设置 MySQL-root-password。

docker-compose.yml

version: '3'

services: 
  docker-mysql:
    image: mysql:latest
    container_name: docker-mysql
    command: --init-file /data/application/init.sql

如何连接到 MySQL 容器？ 我的 docker-compose-file 有问题吗？ 还是需要打开3306端口？

【问题讨论】：

从日志spring-boot-jpa-docker-webapp_1 | Message : Access denied for user 'root'@'172.19.0.3' (using password: NO)您的应用程序仍在使用根凭据对数据库进行身份验证，请先检查您的应用程序。

您的数据库是否允许访问该端口？我会将 PORT : 添加到撰写文件的数据库设置中。在你的情况下，也许 EXPOSE 而不是 PORT 就足够了

【参考方案1】：

从 Spring Boot 2.x 开始，flyway configuration keys need to be prefixed 和 spring.：

spring.flyway.user=thelegend27
spring.flyway.password=1234

没有该前缀，您的设置将被忽略，默认为 root 用户和空密码。

设置空的 MYSQL_ROOT_PASSWORD 环境变量会起作用，除非有错字：

- MYSQL_ALLOW_EMPTY_PASSWOR=yes

应该是：

- MYSQL_ALLOW_EMPTY_PASSWORD=yes
