Docker swarm cluster in AWS

1 minute read

Containers, containers, containers everywhere!

During the last year, I’ve been talking and showing docker containers. However, because of possible network issues (speed, firewall, latency, etc) in some places, I prefer to run my docker host (daemon) in the cloud. To make that possible, I use Docker Machine which contains drivers for many cloud providers like Amazon, Azure, GCE, VirtualBox, etc. Since I’ve been using AWS for while and docker-machine has a driver for it, the use of AWS to run a docker daemon seems a good choice.

As I’ve told in a previous post, I have an existing test environment that I use to explore and show different container’s tools and platforms (docker, docker-compose, swarm, kubernetes, openshift, etc). This environment allows me to simulate docker networks and scaling. To be able to simulate multi-host docker containers, I need to have multiple hosts. For simple scenarios and to show a docker container environment, the use of docker-swarm + docker-compose running in AWS seems to be fair enough.

If you want to try docker swarm in AWS, I recorded the following screencast that guides you through the steps to run it. For a production-ready container based platform, I use and suggest OpenShift Enterprise v3.

I hope this information is useful for you.
