Cadvisor: cAdvisor + nginx in different then "/" context

[wololock]

Hello,

I'm trying to run cAdvisor docker image with nginx proxy. The problem is that I need to set up a proxy from different then root context - my goal is to have cAdvisor running behind e.g. http://localhost/cadvisor/ Here is my exemplary nginx config:

server {
  listen 82;
  server_name ${HOSTNAME};

  set $cadvisor cadvisor.docker;

  location ~ ^/cadvisor/(.*)$ {
    rewrite ^/cadvisor/(.*) /$1 break;
    proxy_pass              http://$cadvisor:8080;
    proxy_set_header        Host $host;
    proxy_set_header        X-Real-IP $remote_addr;
    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_connect_timeout   150;
    proxy_send_timeout      100;
    proxy_read_timeout      100;
    proxy_buffers           16 64k;
    proxy_busy_buffers_size 64k;
    client_max_body_size    256k;
    client_body_buffer_size 128k;
  }
}

The problem is that application assumes that the web context is set to "/", that's why I get redirected to http://localhost:82/containers/ after accessing http://localhost:82/cadvisor/

Is it possible to define application base context path to make cadvisor running behind custom nginx location? Any help will be appreciate

Hi @wololock, yeah this is a pain point we've been seeing a lot lately. I think it is time we tackle it. The suggestion so far has been to make links relative to allow for reverse proxying. This should work in your case too I believe.

I am closing this as a dup of #596, but I will try to find some time to tackle it this week. Or if you're up for it feel free to send a PR :) it should be a relatively small change and mostly localized to the pages/ directory.

This issue has been closed for a while but I just came across it trying to get this working. Is there documentation somewhere for how the relative path is set? The nginx config listed above does not work.

@wololock would you mind sharing a working nginx config? Thanks!

guys I'm trying to achive this and I'm one step from surrendering. I've tried this the zuul proxy

zuul config:

zuul:
  routes:
      cadvisor:
      path: /cadvisor1/**
      url: http://10.0.0.11:9002/ 
      stripPrefix: false

• my cadvisor container is portmapped 10.0.0.11:9002:8080

It might be also a L8 Problem so I appreciate any hints.
is there maybe and option to the set for the "rootdir variable" in your code?

Looks like it is still broken, see https://github.com/google/cadvisor/pull/680
