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.

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.

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 On Mon, Nov 11, 2019 at 2:50 AM David Villasmil < david.villasmil.work(a)gmail.com&gt; wrote: > 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. > > Regards, > > David Villasmil > email: david.villasmil.work(a)gmail.com > phone: +34669448337 > > > On Sun, Nov 10, 2019 at 9:22 PM Alex Balashov &lt;abalashov(a)evaristesys.com&gt; > wrote: > >> -A ... oh wow.

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 Alex Balashov &lt;abalashov(a)evaristesys.com&gt; schrieb am Mo., 11.
