[Freeswitch-users] Docker or a traditional VM-based deployment?

Tue Aug 11 08:06:55 UTC 2020

We use Docker throughout our stack, with the exception of FreeSWITCH. You
can run FreeSWITCH in docker and I'm sure for some people it will have
advantages. There are a few issues I ran into:
- FreeSWITCH needs a very large number of open ports when using SIP
(thousands). Docker is not designed for this and this is the reason people
tell you to use host networking (that way you skip the docker port mapping
system).
- Some external dependencies might be hard to combine with docker. In our
stack we use FreeSWITCH with Sangoma PRI cards and I haven't managed to get
the driver working inside docker, something goes wrong with using the
device inside the container.

In my experience you also end up needing to build your own docker image -
you're likely to have custom extension needs. The Dockerfiles that I found
online did not have the set of extensions I needed and I think were also
not the latest Debian/FreeSWITCH versions. There are not many pre-defined
images available online.

If you use a vanilla FreeSWITCH setup, you don't mind host networking,
and/or you're working on a machine that's not running Debian I can see some
advantages to using docker (it allows you to install the system in a Debian
environment even on a non-Debian host).

Cheers,
Sam
