run node apache-exporter in same docker container as Apache

Question

I am running node apache-exporter (https://github.com/Lusitaniae/apache_exporter) in the same Docker container (build from httpd image) as Apache itself. (So am able to distribute the service directly with the container by one Dockerfile and one docker-compose other like using two Dockerfiles and combine the 2 containers in one docker-compose file.)

The apache-exporter (and the Apache server) runs and I can see the apache-up data in Prometheus/Grafana.

I have inserted the Location block inside my httpd.conf

<VirtualHost *:80>
  ServerName XXX.XXX.XXX.XX
  ServerAlias www.XXX.XXX.XXX.XX
  <Location /server-status>
    SetHandler server-status
    #Require local
    Require host example.com
    #Require ip YYY.YYY.YYY.YYY 
  </Location>
  Redirect permanent / https://XXX.XXX.XXX.XXX
</VirtualHost>

XXX.XXX.XXX.XXX = external IP, YYY.YYY.YYY.YYY = IP inside docker network and loaded the modules

LoadModule authn_core_module modules/mod_authn_core.so
LoadModule authz_host_module modules/mod_authz_host.so

But I got the error:

level=error msg="Error scraping apache: error scraping apache: Get \"https:///XXX.XXX.XXX.XXXserver-status/?auto\": dial tcp: lookup XXX.XXX.XXX.XXXserver-status on YYY.YYY.YYY.YYY: no such host" source="apache_exporter.go:571"

What is wrong? Is a / missing somewhere? Do I have to write the Location block inside another VirtualHost block using another ServerName? Do I have to set --scrape_uri? I guess it is just a stupid mistake by me because the / is missing between IP and server-status. I seems that the Location is not considered and thus the URL is processed by Redirect permanent. Using several ProxyPass inside a VirtualHost is possible when placing the / redirection last.

I want to restrict access to server-status to the Apache-container itself.

Simply removing `Redirect permanent` might help. That is, an automatic redirect to `server-status` may already be in place. — Anaksunaman, Nov 29 '21 at 10:15
Thanks a lot - it works. I also needed a `Require all granted` inside the location block. — LeifSec, Nov 30 '21 at 06:50

It works using this configuration:

<VirtualHost *:80>
  ServerName XXX.XXX.XXX.XX
  ServerAlias www.XXX.XXX.XXX.XX
  <Location /server-status>
    SetHandler server-status
    Require all granted
    Require host example.com
  </Location>  
</VirtualHost>
