问题描述
设置
- 猕猴桃-最新
- MysqL -latest（v8.0.21）
- 操作系统-mac
我如下更改了docker-compose.yml，它可以启动两个容器。

当我执行docker exec -it kiwi_web /Kiwi/manage.py migrate时，会收到一些错误消息。
我正在尝试将用户密码的加密方法从caching_ sha2_ Password更改为MysqL_native_password，但是它仍然弹出相同的错误消息。
错误的跟踪：

上述异常是以下异常的直接原因：

解决方法
您正尝试将正式的MySQL docker镜像与docker-compose.yml配置用于默认情况下Kiwi TCMS使用的CentOS MariaDB镜像。
在https://hub.docker.com/_/mysql上快速浏览MySQL的容器映像，它告诉我它不支持MariaDB映像中使用的某些环境变量。
我看到的错误是由尝试使用似乎与MySQL不兼容的mariadb客户端库（进行连接）引起的。而且我认为这些天MariaDB和MySQL最新版本之间存在许多不兼容性。
所以您需要做两件事：
-
弄清楚如何根据其文档通过环境变量正确配置MySQL容器
-
弄清楚MariaDB客户端库是否可以与MySQL服务器一起工作。
另请参见https://docs.djangoproject.com/en/3.0/ref/databases/#mariadb-notes。
对于2），您可以在GitHub上打开一个问题，这样我们就不会忘记将其添加到我们的测试套件中。 IDK在我的头顶上，最近mysql / mariadb库的状态是什么，是否可以并行安装和使用它们，或者它们是否会相互冲突。
