How about to create set of systemd drop-in for cloud providers and then
package them?
User will simple install package like "kamailio-cfg-google"
or "kamailio-cfg-amazon" and get part of kamailio runtime config.
Please comment here

You can also update kamailio.cfg to include
listeners.cfg
Example. Need add to kamailio.cfg
####### Listeners ##########
include_file "/var/run/kamailio/listeners-eth0.cfg"
Before kamailio started you will generate listeners.cfg file.
This may by done by drop-in file.
Need create "/etc/systemd/system/kamailio.service.d/10-listners-eth0.conf"
with content
[Service]
ExecStartPre=/bin/curl -s -S --output
/var/run/kamailio/listeners-eth0.cfg
http://169.254.169.254/latest/meta-data/public-ipv4
ExecStartPre=/bin/sed --in-place --regexp-extended -e
's/(.*)/listen=udp:\1:5060\nlisten=tcp:\1:5060\n/'
/var/run/kamailio/listeners-eth0.cfg

That's the one, thanks @Karsten!
More info, i changed my systemd unit to execute a script when
starting up, like so:
# cat /etc/systemd/system/multi-user.target.wants/kamailio.service
[Unit]
Description=Kamailio (OpenSER) - the Open Source SIP Server
After=network.target
[Service]
Type=forking
Environment='CFGFILE=/etc/kamailio/kamailio.cfg'
Environment='SHM_MEMORY=64'
Environment='PKG_MEMORY=8'
Environment='USER=kamailio'
Environment='GROUP=kamailio'
EnvironmentFile=-/etc/default/kamailio
EnvironmentFile=-/etc/default/kamailio.d/*
# PIDFile requires a full absolute path
PIDFile=/var/run/kamailio/kamailio.pid
ExecStart=/etc/kamailio/startkam.sh
Restart=on-abort
[Install]
WantedBy=multi-user.target
And /etc/kamailio/startkam.sh is like:
#!/bin/bash
MYSQL=$(/etc/kamailio/aws-getpass.sh dev us-east-1 dburl)
SHM_MEMORY=64
PKG_MEMORY=8
USER=kamailio
GROUP=kamailio
CFGFILE=/etc/kamailio/kamailio.cfg
/usr/sbin/kamailio -P /var/run/kamailio/kamailio.pid -f $CFGFILE -m
$SHM_MEMORY -M $PKG_MEMORY -u $USER -g $GROUP -A "DBURL=\"$MYSQL\""
-A
"CBDBURL=\"cb=>$MYSQL\"" -A
"ASGDBURL=\"asg=>$MYSQL\""
which in turn calls /etc/kamailio/aws-getpass.sh, which is the actual
script talking to AWS via BOTO3 to get the data i need.
You can just change the params and use them in your kam script normally
like:
modparam("acc", "db_url", DBURL )
Hope that helps.
