RTL-SDR is a very cheap software defined radio that uses a DVB-T TV tuner dongle based on the RTL2832U chipset. The RTL-SDR is also often referred to as RTL2832U, DVB-T SDR, RTL dongle or the '$20 Software Defined Radio'. There are many other software defined radios better than the RTL-SDR, but they all come at a higher price.
Container Clustering Using Docker Swarm & Docker Machine
May 6, 2016
Docker Swarm is native clustering for Docker. It turns a pool of Docker hosts into a single, virtual Docker host. Docker Machine is a tool for provisioning and managing your Dockerized hosts (hosts with Docker Engine on them). Typically, you install Docker Machine on your local system. Docker Machine has its own command line client docker-machine and the Docker Engine client, docker.
