Just run this from your Mac terminal and it'll drop you in a container with full permissions on the Docker VM. This also works for Docker for Windows for getting in Moby Linux VM (doesn't work for Windows Containers).

| 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. |

By the end of this quick guide, you will know how to compile a Phoenix app release using Exrm and run it inside a Docker container. I've found only a couple of articles that discuss getting an Elixir app up and running inside a Docker container, and even those only touched on some parts of the process. The idea is that this guide will give you a full end-to-end example of how to get all the pieces and parts working together so that you are able to deploy your Phoenix application inside a Docker container.
| Tmux is a "terminal multiplexer", it enables a number of terminals to be accessed and controlled from a single terminal. | |
| If you use Debian/Ubuntu, you can just run apt-get install tmux, and voila. | |
| Since the title was about centos 7, then do the following step to install tmux. | |
| (1). tmux has a library dependency on libevent which, of course, isn’t installed by default. | |
| $ wget https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz | |
| $ tar xzvf libevent-2.0.21-stable.tar.gz | |
| $ cd libevent-2.0.21-stable | |
| $ ./configure && make |
