How to create a Diameter lab via Docker

winpty docker run -it debian:stable bash

apt update
apt -y upgrade
apt install -y wget gnupg gnupg1 gnupg2 nano
wget http://www.freediameter.net/packages/repository.key
apt-key add repository.key

nano /etc/apt/sources.list

deb http://www.freediameter.net/packages/debian sid contrib
deb-src http://www.freediameter.net/packages/debian sid contrib

apt update
apt upgrade
apt install freediameter

Se lo faccio partire direttamente, da errore:

16:35:27 NOTI freeDiameterd framework is stopping...
16:35:27 NOTI Shutting down server sockets...

Devo allora creare i certificati.
