<p>Hello,</p>
<p>just remembered that a while ago I added support for the config
file name '-' (dash/minus char) which means kamailio reads the
config from standard input. This can be used to direct content of
the kamailio.cfg from a safe system. For example, if one stores
the config file on a web server, can do:</p>
<p>curl <a class="moz-txt-link-freetext" href="https://myserver.com/kamailio.cfg">https://myserver.com/kamailio.cfg</a> | kamailio -f -</p>
<p>It can be a webserver asking for password.</p>
<p>In the context of keeping it encrypted, there can be a tool that
fetches and decrypts kamailio.cfg content and prints it to the
standard output.</p>
<p>Using this, not even kamailio.cfg needs to be saved on the local
disc.</p>
<p>On the other hand, as I said in a previous response, if an
untrusted person gets access with root privileges, then it can
attach to a running kamailio process with gdb and read from
memory.</p>
<p>Cheers,<br>
Daniel<br>

<div>Hi Robert,<br>
<br>
</div>
I'm not security expert and I'm quite new in docker, but I
think password in Docker container which will be in clear text
saved somewhere should not be a problem, as far as you do not
save this password to image or git and etc...<br>

<div>I think best way for you is to use docker secret and
generate then config file for Kamailio using this docker
secrets and then start Kamailio and for all of this you need
to write some kind of Entrypoint script. Here is example how
something similar do Homer Sipcapture, they set environment
variables in docker-compose and then generate config file
based on this, but you can use probably docker secrets instead
of environment variables:</div>

presumably leave the clear text footprint I'm trying to
avoid, albeit in a non-Kamailio file. I’ve made a start on
an approach to read from a file, Docker secrets are
basically just files, but the Docker platform handles them
securely.<br>
