[Freeswitch-users] FreeSWITCH on Docker

[Colin Morelli]

Ehsan,

While I haven't personally run heavy load FS instances in containers yet
(only testing), I can't see a reason this would be a problem. Docker
containers are just glorified Linux cgroups, and have virtually zero
measurable overhead - especially so if you're not actually using CPU/memory
limitations.

A couple of things to consider:
Given that FS is likely to use a lot of bandwidth, you're probably best off
using host networking if possible (avoids significant numbers of iptables
rules or userland proxies on older version of docker). This will also help
avoid ugliness with getting FS to properly handle the local Docker bridge
IP.
Local disk I/O *will* be slower in Docker, but how much so largely depends
on on which storage driver you use. That said, if you're considering
putting FS in Docker I assume you're likely not doing local disk I/O in FS
anyway.

Hopefully that's helpful.

Best,
Colin
