hi team,

I am trying to setup graylog 3.0.2 in docker containers, for now i am using the default port 9000 inside the container and while running the container i am binding it `-p 8081:9000` with a different port. and when i try to access it on the browser, it is still trying to connect with 9000 for vendor.js/app.js/config.js.

can someone help me on this?

i am creating a cluster, graylog master configuration is also posted here .

you need to set your `http_external_uri` to where your Browser can reach the Graylog API:

[https://docs.graylog.org/en/3.0/pages/configuration/server.conf.html#web-rest-api](https://docs.graylog.org/en/3.0/pages/configuration/server.conf.html#web-rest-api)

so it i will be `http_external_uri` = 0.0.0.0:9000 or 0.0.0.0:8081 ?

UPDATE: i tried both and then i understand 8081 will work for me, now can see graylog default login page and but node page is not showing any information about my cluster and input is also fail to start, this is what i am getting in error

```

please read the `http_publish_uri` default behaviour …

and understand what `0.0.0.0` means and read the docs why that is not possible for `http_external_uri`
