Docker Compose模板(Spring Boot + mysql + redis + rabbitmq)：

注：需要将application.yml中的host替换为容器名称

1. **mysql environment配置失效** 当指定启动项--init-file /tmp/tables.sql时，environment内的配置会部分失效。例如MYSQL_DATABASE: textgen中，textgen数据库无法创建。因此需要在tables.sql中加入建库语句。 2. **mysql public key retrieval is not allowed** mysql 8.0 默认使用 caching_sha2_password 身份验证机制 （即从原来mysql_native_password 更改为 caching_sha2_password。） 需要在tables.sql加入：

USE mysql;
UPDATE user SET host = '%' WHERE user = 'root';
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'gE61dRVX';
FLUSH PRIVILEGES;
