Phoenix Nodes

First I created 3 droplets on digital ocean with 4-cores and 8GB of RAM. Login as root to each and run:

sysctl -w fs.file-max=12000500
sysctl -w fs.nr_open=20000500
ulimit -n 4000000
sysctl -w net.ipv4.tcp_mem='10000000 10000000 10000000'

	# Specifically we are trying to do 2 things with the erlang `:ssh` module:
	# Make a connection (use :ssh.connect/4`) and pass in the ssh key from something other than a file on disk
	# And then with an open connection, bind the connection to a local port (i.e. setup a ssh tunnel)
	# use :ssh.tcpip_tunnel_to_server/5 or :ssh.tcpip_tunnel_to_server/6
	# Example (working) code:


	defmodule SSHTunnel do
	@local_port 9999
	@remote_port 1234

	defmodule NestedWeb.FormLive do
	use NestedWeb, :live_view
	require Logger

	defmodule Form do
	use Ecto.Schema
	import Ecto.Changeset

	embedded_schema do
	field :name, :string

	defmodule MyAppWeb.GettextTest do
	use ExUnit.Case
	import MyAppWeb.Gettext

	# A unit test for Gettext translations that checks if the original and the translation
	# use the same HTML tags.
	#
	# Uses Floki to parse HTML.

	describe "translations" do

	#!/bin/bash
	if [ "$EUID" -ne 0 ]
	then echo "Please run as root"
	exit
	fi

	apt-get install pkg-config libmagickwand-dev -y
	cd /tmp
	wget https://pecl.php.net/get/imagick-3.4.4.tgz
	tar xvzf imagick-3.4.4.tgz

	I have found this interesting for debugging, but also fun to hear web pages
