Re: [SR-Users] Kamailio in cloud environments

2019-11-10 Thread Karsten Horsmann

Nice idea Alex.

I use import_file and include_file and fill this with my settings from
Puppet.

Many ways to get your config strings.

There is also some ENV stuff for Kamailio to feature config strings into
startup for container environments AFAIK.

Cheers
Karsten

Re: [SR-Users] Kamailio in cloud environments

2019-11-10 Thread Alex Balashov

I prefer more flexibility, and so use a slightly more ornate approach
involving the Jinja2 template engine (inspired by Jango)[1] and Python
3. I'll spread it in the network in the hope that it helps someone.

--- kamailio-settings.yaml ---
listeners:
  - proto: udp
addr: 127.0.0.1
port: 5060

  - proto: tcp
addr: 172.30.105.10
port: 5060

db_conn:
  driver: mysql
  user: kamailio_ro
  password: abc123
  host: 172.30.106.11
  name: kamailio
--

And the Kamailio config:

--- kamailio.cfg.tpl 
#!define DB_URL "{{ db_conn['driver'] }}://{{ db_conn['user'] }}:{{ 
db_conn['password'] }}@{{ db_c
onn['host'] }}/{{ db_conn['name'] }}"

...

{% for l in listeners -%}
listen={{ l['proto'] }}:{{ l['addr'] }}:{{ l['port'] }}
{% endfor %}
-

And:

--- apply.py ---
#!/usr/bin/python3

import sys, os, re, yaml
from jinja2 import Template, Environment

env = Environment()
cfg_buf = None
settings = None


with open('/usr/local/etc/kamailio/kamailio.cfg.tpl', 'r') as f:
  cfg_buf = f.read()

tpl_instance = env.from_string(cfg_buf)

with open('kamailio-settings.yaml', 'r') as f:
  settings = yaml.load(f.read(), Loader=yaml.FullLoader)

finished = tpl_instance.render(settings)

with open('/usr/local/etc/kamailio/kamailio.cfg', 'w') as f:
  f.write(finished)


Then, this goes in the systemd unit:

   ExecStartPre=/usr/bin/python3 /opt/evariste/scripts/apply.py

Result:

---
#!define DB_URL "mysql://kamailio_ro:abc123@172.30.106.11/kamailio"

...

listen=udp:127.0.0.1:5060
listen=tcp:172.30.105.10:5060

Re: [SR-Users] Kamailio in cloud environments

2019-11-10 Thread Sergey Safarov

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

Re: [SR-Users] Kamailio in cloud environments

2019-11-10 Thread Sergey Safarov

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

Re: [SR-Users] Kamailio in cloud environments

2019-11-10 Thread David Villasmil

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.

Re: [SR-Users] Kamailio in cloud environments

I needed to discover the user/pass for the dB when kamailio starts so as
not to store it locally. I get the data via an AWS script, then start
kamailio passing the parameters, then use of those in the script. You can
do exactly this to get and set the current ip address.

I don’t know how to share a thread from this mailing list, but search for
the subject “ define a DBURL with SLQOPS fails” and you will find all info
there.

They generally do the latter, especially since public IP discovery
mechanisms tend to be specific to the cloud provider.

But various templating mechanisms make this quite easy to do.

I see, since all the connections are TCP, there is no issue with kamailio 
knowing its public IP? Normally that IP is embedded in VIA headers etc.

I’ve been reading your thread about TCP connection reuse with interest ;)  Will 
let you know if I find some way around it.

2019-11-10 Thread Joel Serrano

I’m working on something similar, what cloud are you using?

In my case, using GCP, I have a script that queries the metadata API and
uses information from there, but for the setup I’m trying out, I use the LB
public IP not the VM one.

I’m curious as to how you plan to get it to work, why would you need the
public IP of the VM?

Also, I’m having trouble getting Kamailio to use existing (established) TCP
connections when it’s not the initial request...

I’d love to hear if you get it working!

Cheers,
Joel.
