Does GRAYLOG_WEB_ENDPOINT_URI has to be changed before running docker-compose? https://gist.github.com/indigo423/b6f1594e2512fddb0e677435937e8937#file-graylog2-docker-compose-yml-L65
In my test it didn't work to run http://ip:9000 to get the web ui. If I can translate my-graylog-web-server to the servers' IP address it works.

yes it needs to be the endpoint you want to consume your service which is related to your environment.

Contains 2 ulimit and volumes sections.
