Jenkins reverse proxy on single domain with multiple apps

Sun Feb 25 08:08:28 UTC 2018

Hello,

I am trying to setup a reverse proxy on a single domain to host multiple
apps separated by URI, for example:
http://localhost/app1
http://localhost/app2
etc.

Right know having problems with reverse proxy jenkins which sends HTML page
in HTTP reply with relative paths eg. /static/abc/css/common.css

So far I have rewritten the content to the login screen as per below but I
want to know if there is any other way to rewrite this automatically:

location /jenkins {
        proxy_pass    http://jenkins:8080/;
        sub_filter 'url=/login?from=%2F' 'url=/jenkins/login?from=%2F';
        sub_filter "('/login?from=%2F')" "('/jenkins/login?from=%2F')";
        sub_filter_once off;

    }

Once I hit http://localhost/jenkins I am getting whole bunch of 404 because
of relative links as per the HTML response below

  <!DOCTYPE html><html><head resURL="/static/a4190cd9" data-rooturl=""
data-resurl="/static/a4190cd9">
