When the zipkin host isn't localhost..

[codefromthecrypt]

from @dragontree101

my zipkin-server is 1.16 and change zipkin-ui in 0.0.1 i use new zipkin-ui, but has error, i need change some ui-config?

i use config is

environment=
  KAFKA_ZOOKEEPER="10.215.242.11,10.215.242.12,10.215.242.13:2181/kafka-offline",
  STORAGE_TYPE="elasticsearch",
  SELF_TRACING_ENABLED="true",
  ES_CLUSTER="prod",
  ES_HOSTS="http://10.215.242.15:9200",
  ES_PIPELINE="zipkin",
  KAFKA_STREAMS="4",
  QUERY_PORT="8080"

i think to change localhost to zipkin-server's ip? i am not deploy zipkin-server in my local.

looking at the code, it seems there are some constants relating to the fully-qualified api host. is there a way to use a relative path instead? (forgive me, if I misunderstand them)

I am in the same boat , How can I have the localhost replaced with the relative path

this is just waiting on work to do it. does anyone have time to help?

What's the general idea for configuring this UI?

I see that docker-zipkin uses a nginx to proxy the actual backend onto the same server that hosts the UI, and ZipkinService hardcodes 'localhost' and the port here: https://github.com/openzipkin/zipkin-ui/blob/master/src/app/zipkin/zipkin.ts#L155

Seems that one needs to do two things: kill the port reference there, and then fix all places that work with localhost?

@ankon so when in development (and also many sites), the port is 9411. So, I supposed some means of configuring the api endpoint ex (http://localhost:9411) would be what's needed. Then, whatever parameter is needed would be passed to the deployment.

One idea is to expose the api endpoint as a part of config.json, which is how the old UI gets its config, lacking that assume http://localhost:9411. There is a chicken/egg problem, of course as config.json is served by the host listening on 9411!

TL;DR; I don't know the best way, but what you've mentioned makes sense.

@charlescui made a suggestion here https://github.com/openzipkin/docker-zipkin/issues/134#issuecomment-288403568

here's an example implementation https://github.com/openzipkin/zipkin-ui/pull/34 I think others should comment wrt the configuration approach.

#34 suggests separate env variables to assign this.. like export ZIPKIN_HOST=172.16.10.56 ZIPKIN_PORT=32008 please give feedback if this works for you or not.
