RJ Nowling commented on ZEPPELIN-10:
------------------------------------
[~epakhomov] is currently using -p (what you suggested) but wants to use -P
(random port assignment). It's not possible to use -P because Zeppelin uses
two ports and needs to know what the second port is when generating URLs.
The use of two ports makes forwarding or proxying Zeppelin a challenge. It
also causes problems with setting up authentication. I'm wondering if it would
be possible to change the code to use a single port but different paths?
> Zeppelin doesn't compatible with docker.

> Key: ZEPPELIN-10
> URL: https://issues.apache.org/jira/browse/ZEPPELIN-10
> Project: Zeppelin
> Issue Type: Bug
> Components: GUI
> Affects Versions: 0.5.0
> Reporter: Egor Pakhomov
> Priority: Critical
>
> Zeppelin put UI on ZEPPELIN_PORT and web_socket on ZEPPELIN_PORT+1. When you
> run docker with standart -P
> argument(https://docs.docker.com/userguide/usingdocker/) it maps these ports
> to some other ports. For example you set ZEPPELIN_PORT=8080 and export 8080,
> 8081. But in reality it would be some other ports(49159, 49160). And Zeppelin
> don't know anything about them. And UI doesn't work properly.
