MicroService Proxy Gateway Solutions

Kong, Traefik, Caddy, Linkerd, Fabio, Vulcand, and Netflix Zuul seem to be the most common in microservice proxy/gateway solutions. Kubernetes Ingress is often a simple Ngnix, which is difficult to separate the popularity from other things.

This is just a picture of this link from March 2, 2019

README

This gist assumes you are migrating an existing site for www.example.com — ideally WordPress — to a new server — ideally Ubuntu Server 16.04 LTS — and wish to enable HTTP/2 (backwards compatibile with HTTP/1.1) with always-on HTTPS, caching, compression, and more. Although these instructions are geared towards WordPress, they should be trivially extensible to other PHP frameworks, other FastCGI backends, and even non-FastCGI backends (using proxy in lieu of fastcgi in the terminal Caddyfile stanza).

Quickstart: Use your own naked and canonical domain names instead of example.com and www.example.com and customize the Caddyfile and VCL provided in this gist to your preferences!

These instructions target Varnish Cache 4.1, PHP-FPM 7.0, and Caddy 0.10. (I'm using MariaDB 10.1 as well, but that's not relevant to this guide.)

Warnings:
* as 2017-02-24 (Docker version 1.13.1), swarm mode is not officially recommeded from production. 
* There are a few bugs like swarm stop working when changing network. https://github.com/docker/docker/issues/29580
* Some kernel options (like ulimit) are still not supported on swarm when creating services https://github.com/docker/docker/issues/25209
* As 2018-09-24 docker swarm is very unstable and definitely not ready for production. Witch each new version of docker, swarm is more unstable than the previous one. I would strongly recommend avoid using swarm all together. (See issues https://github.com/moby/moby/issues/36696 and https://github.com/moby/moby/issues/37725 )
* 2021-09-10: this is an old gist with experimental configuration. Don't use this for production or anything relevant. Trust me. Also mongo versions are quite old. If you are just playing with mongo and docker swarm, go ahead.

Servers are server1 (mongos and configsrv), server2 (shard1), server3(shard2).

Install dnsmasq

Via brew or other method

Set up DNS resolver order

In order to work on every connection and on any TLD, dnsmasq needs to be the first DNS resolver receving the query.

And since dnsmasq is a local process, all DNS queries need to go to 127.0.0.1

On macOS, /etc/resolv.conf is automaticaly created, depending on a variety of things (network settings, etc), so it cannot be edited.

Docker Swarm Mode Ports

Starting with 1.12 in July 2016, Docker Swarm Mode is a built-in solution with built-in key/value store. Easier to get started, and fewer ports to configure.

Inbound Traffic for Swarm Management

• TCP port 2377 for cluster management & raft sync communications
• TCP and UDP port 7946 for "control plane" gossip discovery communication between all nodes
• UDP port 4789 for "data plane" VXLAN overlay network traffic
• IP Protocol 50 (ESP) if you plan on using overlay network with the encryption option
