I'm glad to see that the PR went through.
I got it to work by setting
-Dspark.ui.reverseProxy=true in SPARK_MASTER_OPTS.
Is this the correct way to proceed?

I'm glad to see that the PR went through.
However I'm not sure how this is supposed to work.
The Master webui gives me this :
worker-20161023152840-172.28.0.8-42846 linking to the internal docker IP.
So I tried to access the worker UI from
http://spark-master-public-ip/worker-20161023152840-172.28.0.8-42846
http://spark-master-public-ip/target/worker-20161023152840-172.28.0.8-42846
http://spark-master-public-ip/target/20161023152840-172.28.0.8-42846
(from what I read in the discussion the last one should have been correct)
However I'm stuck at the master's webui.
I'm running 2.1.0 latest nightly build http://people.apache.org/~pwendell/spark-nightly/spark-master-bin/latest/

> Key: SPARK-15487
> URL: https://issues.apache.org/jira/browse/SPARK-15487
> Project: Spark
> Issue Type: Improvement
> Components: Web UI
> Affects Versions: 1.6.0, 1.6.1
> Reporter: Gurvinder
> Assignee: Gurvinder
> Priority: Minor
> Fix For: 2.1.0
>
>
> Currently when running in Standalone mode, Spark UI's link to workers and application drivers are pointing to internal/protected network endpoints. So to access workers/application UI user's machine has to connect to VPN or need to have access to internal network directly.
> Therefore the proposal is to make Spark master UI reverse proxy this information back to the user. So only Spark master UI needs to be opened up to internet.
> The minimal changes can be done by adding another route e.g. http://spark-master.com/target/<endpoint>/ so when request goes to target, ProxyServlet kicks in and takes the <endpoint> and forwards the request to it and send response back to user.
> More information about discussions for this features can be found on this mailing list thread http://apache-spark-developers-list.1001551.n3.nabble.com/spark-on-kubernetes-tc17599.html
