The Teradek Bond is cellular bonding solutions allows you to transmit 1080p HD video over aggregated bandwidth from several network interfaces, including 3G/4G/LTE, WiFi, BGAN, and Ethernet*
Sputnik Server using to combine the data packets from Bond’s modems into a cohesive video stream, your live broadcast must first be transmitted to a Sputnik server hosted on Amazon’s EC2 cloud or on your own Linux computer with a publicly addressable TCP port. Sputnik is Teradek’s free software application between Bond and your streaming destination, whether its a content delivery network or an IPTV decoder. (see below diagram)
below is sample of Sputnik web base interface.
Well, That's enough for Teradek Bond info. It not my point here. I just wanna note that how to setup sputnik server. I use docker which very very easy. I fork the docker image from texastribune/sputnik (sputnik 2.2.1) to patrickz/sputnik, but I use latest version (Sputnik 2.4.3, released on 2015-11-11)
After install docker then use command
docker run -p 5111:5111 -p 1957:1957 -p 554:554 --detach --name sputnik patrickz/sputnik
then docker ps -a. You should see as below image
go to URL http://your-ip.com:1957/ with default access - user: admin, password: admin (Don't forget to change password).
