HAProxy / Nginx /Docker/Port

[coderlol]

HAProxy 1.4, nginx 1.4.7, docker 0.10.0

User --port 80-> HAProxy --10000-> Docker --8080-> Nginx hosting Kibana

Nginx runs inside Docker listening to port 8080
Docker maps port 10000 to port 8080
HAProxy listens port 80 and direct /kibana to port 10000

The problem seems to be Kibana or Nginx "rewrites/accesses" the URL and so, the user browser indicates Kibana code attempts port 8080 instead of 80.

Here is what is shown on the browser when user tries to go to 192.168.1.200/kibana

"http://192.168.1.200:8080/kibana/index.html#/dashboard/file/logstash.json"

If HAProxy also listens to port 8080, all works. If not, it won't work.

Any idea if the issue of not preserving the external port a Kibana, nginx, or HAProxy setup issue? I figure, somewhere along the path, the external/original port information got lost.

I don't think it is a HAProxy. If HAProxy is eliminated, and docker maps 8080 to nginx 8080, it works. If docker maps any other port number to nginx 8080, it won't work. Perhaps, additional HTTP headers need to be passed along to nginx. nginx only "knows" 8080...I figure...

I'm afraid I can't really debug this setup. Kibana doesn't rewrite the URL in any way, it will always use the URL you specify

Could you try Kibana behind a proxy?

User --28080--> Proxy --8080--> nginx/kibana

Key is proxy is not listening on 8080.
