## Ask your question here
使用 xds 部署在 kubernetes 后，会报 metadata 和 config server 相关的错误：
```plain

```
这是否意味着 dubbo3 部署在 kubernetes 后，并没有利用 kubernetes 的能力作为 metadata server 和 configserver，还是需要我们额外部署这两个组件？

我看实例里不需要部署元数据中心，元数据中心对应的配置项直接指定了20885端口，请问在这个过程中，元数据中心是由谁部署的？20885端口是谁的组件提供的元数据中心能力？

xds不需要EnVoyFilter就能运行了

不需要额外部署了，可能是日志打的有问题
