involving the Jinja2 template engine (inspired by Jango)[1] and Python<br>
3. I'll spread it in the network in the hope that it helps someone.<br>
<br>
--- kamailio-settings.yaml ---<br>
listeners:<br>
- proto: udp<br>
addr: 127.0.0.1<br>
port: 5060<br>
<br>
- proto: tcp<br>
addr: 172.30.105.10<br>
port: 5060<br>
<br>
db_conn:<br>
driver: mysql<br>
user: kamailio_ro<br>
password: abc123<br>
host: 172.30.106.11<br>
name: kamailio<br>
------------------------------<br>
<br>
And the Kamailio config:<br>
<br>
--- kamailio.cfg.tpl ----<br>
#!define DB_URL "{{ db_conn['driver'] }}://{{ db_conn['user'] }}:{{ db_conn['password'] }}@{{ db_c<br>
onn['host'] }}/{{ db_conn['name'] }}"<br>
<br>
...<br>
<br>
{% for l in listeners -%}<br>
listen={{ l['proto'] }}:{{ l['addr'] }}:{{ l['port'] }}<br>
{% endfor %}<br>
-------------------------<br>
<br>
And:<br>
<br>
--- apply.py ---<br>
#!/usr/bin/python3<br>
<br>
import sys, os, re, yaml<br>
from jinja2 import Template, Environment<br>
<br>
env = Environment()<br>
cfg_buf = None<br>
settings = None<br>
<br>
<br>
with open('/usr/local/etc/kamailio/kamailio.cfg.tpl', 'r') as f:<br>
cfg_buf = f.read()<br>
<br>
tpl_instance = env.from_string(cfg_buf)<br>
<br>
with open('kamailio-settings.yaml', 'r') as f:<br>
settings = yaml.load(f.read(), Loader=yaml.FullLoader)<br>
<br>
finished = tpl_instance.render(settings)<br>
<br>
with open('/usr/local/etc/kamailio/kamailio.cfg', 'w') as f:<br>
f.write(finished)<br>
----------------<br>
<br>
Then, this goes in the systemd unit:<br>
<br>
ExecStartPre=/usr/bin/python3 /opt/evariste/scripts/apply.py<br>
<br>
Result:<br>
<br>
---<br>
#!define DB_URL "mysql://<a href="http://kamailio_ro:abc123@172.30.106.11/kamailio" rel="noreferrer noreferrer" target="_blank">kamailio_ro:abc123@172.30.106.11/kamailio</a>"<br>
<br>
...<br>
<br>
