Building RTPEngine with Docker

Idea is quite simple.
To build rtpengine packet on Debian system, but not having all build dependencies on target machine.
So, we'll use Docker to generate deb files for target system and than - just remove image. This way system will held only minimum needed packets.

As a target, Debian 10 (buster) will be used, as I succeed to install rtpengine mr8.0 (with G.729 support) on it and can't get it working on Debian 9 (maybe use lower version?)

So. All is done on Debian 10 netinst.

• First step - install Docker
  
  apt update
  apt install -y apt-transport-https ca-certificates curl gnupg2 software-properties-common
  curl -fsSL https://download.docker.com/linux/debian/gpg | apt-key add -
  add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/debian $(lsb_release -cs) stable"
  apt update
  apt install -y docker-ce
  
• Prepare Dockerfile

• Build and get deb files
  
  docker build -t rtpengine:build .
  docker create --name rtpengine-build rtpengine:build
  docker cp rtpengine-build:/opt/deb .
• Install rtpengine
  
  
  cd deb
  dpkg -i libbcg729-0*.deb
  dpkg -i ngcp-rtpengine-daemon_*.deb
  apt-get install -f
  dpkg -i ngcp-rtpengine-recording-daemon_*.deb
  apt-get install -f
  dpkg -i ngcp-rtpengine-utils_*.deb
  apt-get install -f
  dpkg -i ngcp-rtpengine-iptables_*.deb
  apt-get install -f
  dpkg -i ngcp-rtpengine-kernel-dkms_*.deb
  dpkg -i ngcp-rtpengine_*.deb
  Idea of repeating apt-get install -f is to apt to add missing packets.
  Next - configure rtpengine as usual
