在K8S集成seata，官方配置

代码

配置文件主要看中间和最底下的代码

中间：主要看

env:- name: SEATA_CONFIG_NAMEvalue: file:/root/seata-config/registry.conf

这代表指定配置文件，下面则是指定ConfigMap

ConfigMap则是seata的config/application.properties文件里的内容

创建后，在阿里的配置项会有这个配置

如果已经有配置项，创建K8S时可以去掉最底层代码

重要

在K8S创建seata，可能在nacos看不到seata的服务，但实际上，seata已经成功运行，并且系统也把事务托管给了seata，我就是这个样子的，nacos找不到，还以为seata没注册成功

nacos配置文件

改了以后，虽然在nacos的服务列表没有seata，但是看了seata的启动日志，发现它已经把系统的事务进行托管，经测试，分布式事务也能正常回滚
