Server operating system version

Ubuntu 22.04

Plesk version and microupdate number

I want to use Grafana to display a large PostgreSQL database. Can I use Grafana from the repository of mys system? I noticed that Grafana is used by Plesk, I have uninstalled the Grafana extension, but Grafana is still running on the system.
grafana/now 10.1.5 amd64 [Installiert,lokal]

systemctl status grafana-server.service
● grafana-server.service - Grafana instance
Loaded: loaded (/lib/systemd/system/grafana-server.service; enabled; vendor preset: enabled)
Active: active (running)

netstat -tunlp | grep 3000
tcp6 0 0 :::3000 :::* LISTEN 654887/grafana

When I try to use Grafana in a docker container, the only thing I get is: gateway time-out.
I wonder why the container says "Port-Mapping: 3000 to 32780"? Why 3000, when this is what the system Grafana is using?

grep 3000 /etc/grafana/*
/etc/grafana/grafana.ini:;http_port = 3000

Grafana is running, just reinstalled the image.
How to connect from the container to localhost? host.docker.internal is not working.

I couldn't find a way to connect from the container to localhost. There must be a way, found nothing about in the plesk support articles. There is an article about starting a container in localhost, but I want to do it, manged by plesk.
