Gour Saha commented on SLIDER-1008:
-----------------------------------
Have you looked at export groups in metainfo.xml? Here is an example file
https://github.com/apache/incubator-slider/blob/develop/app-packages/hbase/metainfo.xml
where an export group *QuickLinks* is defined. Once the app is running the
information can be retrieved using the cmd - {code}slider registry --name
<app_name> --getconf quicklinks{code}
An even simpler example is *Servers* export group in
https://github.com/apache/incubator-slider/blob/develop/app-packages/memcached/metainfo.xml.
> Expose Endpoint of App Component for users to visit

> Key: SLIDER-1008
> URL: https://issues.apache.org/jira/browse/SLIDER-1008
> Project: Slider
> Issue Type: Task
> Components: appmaster, registry
> Affects Versions: Slider 0.81
> Reporter: fengyongshe
>
> After creating Apps，containers are distributed on arbitrary hosts ,also
> random IPC port。how can user visit the app ? One way is to get endpoint by
> manual (eg:netstat -anp|grep {pid})，the way is awful。
> There is the need to expose useful endpoints of App to zk registry path。
> eg: use slider to start a tomcat App，expose the ipc port:
> [zk: localhost:2181(CONNECTED) 7]
>
> get/registry/users/root/services/org-apache-slider/tomcat/components/container-1448969780678-0005-01-000002
> {
> "type" : "JSONServiceRecord",
> "description" : "TOMCAT",
> "external" : [ {
> "api" : "server-xml.http.port",
> "addressType" : "host/port",
> "protocolType" : "tcp",
> "addresses" : [ {
> "port" : "39063",
> "host" : "{host-name}"
> } ]
> } ],
> "internal" : [ ],
> "yarn:persistence" : "container",
> "yarn:id" : "container-1448969780678-0005-01-000002"
> }
> User can get the host/port through zk.
