EBS and EFS Volumes with Docker For AWS using REX-Ray

This procedure will deploy Docker For AWS and go through the steps to build REX-Ray containers. This process will have some hiccups because Docker for AWS will provision resources in different availability zones (AZs). Multiple workers/agents will be spread across AZs (not regions) which means a potential host failure will trigger Swarm to restart containers that could spread across an AZ. If a container is restarted in a different AZ, the pre-emption mechanism for REX-Ray will not work because it no longer has access to the volume in the former AZ.

Deploy Docker for AWS.

Most GStreamer examples found online are either for Linux or for gstreamer 0.10.

This particular release note seems to have covered important changes, such as:

ffmpegcolorspace => videoconvert
ffmpeg => libav

Applying -v will print out useful information. And most importantly the negotiation results.

	defmodule DrainStop do
	@moduledoc """
	DrainStop Attempts to gracefully shutdown an endpoint when a normal shutdown
	occurs. It first shuts down the acceptor, ensuring that no new requests can be
	made. It then waits for all pending requests to complete. If the timeout
	expires before this happens, it stops waiting, allowing the supervision tree
	to continue its shutdown order.
