[SR-Users] kamailio RTP Engine in kubernetes pods

[David Villasmil]

I set postStart and preStop on rtpengine and on freeswitch to basically
insert its ip address in the tables rtpengine and dispatcher.
And on kamailio I have a timer that reloads dispatcher and rtpengine.
On the pods, I set something like “HostNetwork: true”

I’m not at my computer now, but I’m pretty sure it’s something like that.
