Registrator and SkyDNS

We use progrium/registrator and yaronr/skydns (SkyDNS2) to publish information about Docker containers to DNS via A and SRV records. All nodes runs skydns and registrator, and first three nodes are inserted as NS-s into Route53 DNS for services.cluster-name.domain.io. Note, v4 registrator must be used until registrator/124 is resolved.

$ host -t srv mysql-1.services.deis.r53.acp.io deis-6-1.eu.r53.acp.io

pfSense Simple Home Configuration - 2.4.3 / 2.4.4

Starting from Scratch

This is my personal guide for installing pfSense. Hope you find it useful. I made these notes to capture the details of my "install from scratch" to ensure I didn't miss important details. Also, I'm trying build my network with discrete "disposable" components that make the system mutable and less rigid. It does not cover installing any packages like Squid or Suricata as that's way beyond the scope of a basic, functional install.

I migrated from an environment that was at various times running Tomato Toastman 1.28 or Asuswrt-Merlin on Netgear and ASUS routers across four "access points" (one always acting as the firewall/gateway, the rest as APs). It was OK pre-gigabit, but had roaming problems, and I was using large Wifi routers with most of the features disabled. Also, I found that I could easily swamp the network and tank VOIP and Wifi Calling without even trying. The only fix was to throttle everything by using Bandwidth Limit

	# NOTE: Since Docker 1.10 (February 4, 2016), it has been possible to configure the

	# a version of Docker that is at least 1.10!

	# Solves the problem with open ports with docker and ufw
	# As Docker uses the nat table, the filter table FORWARD chain is used and does not touch ufw-input chains as expected.
	# Even for ufw-forward chains it would not work, as DOCKER chains are inserted in front.
	# This is a simple fix that worked for me.
