[SR-Users] RTP Engine in docker

[Alex Balashov]

The main issue I have with running RTPEngine containers in host network mode is that they then cannot simultaneously participate in internal/overlay container networks, defeating efforts to manage them with various orchestration architectures.

You will also need to mark container as privileged container and enable 1-to-1 NAT for RTP port range between host and vm (i recommend using iptables for this instead of using docker port expose feature).

Also there are various dependencies that are not listed in wiki and cause problem in installation of deb packages, which you can install later on after reading the error messages.
