killcity

UPDATE!

I have moved this to my blog. All future updates will be made here: http://killcity.io/2017/08/12/setup-docker-swarm-with-macvlan-plus-consul-and-autoscaling.html

Docker Swarm with Macvlan, Consul and Autoscaling

TL;DR:

This will get you routable containers with IPs on your existing subnets, advertising to Consul. They will also be scalable and placed across a cluster of Swarm hosts. It's assumed that you are already running Consul, so if not, there are a ton of tutorials out there. It's also assumed you know how to install Docker and various Linux kernels.

Bonus: We add an autoscaling API called Orbiter (https://gianarb.it/blog/orbiter-the-swarm-autoscaler-moves).

I just want to run containers, like now, on my existing infrastructure and networks!
