Swarm Mode is taking Docker scheduling by the storm. You tried it in your lab or by setting up a few VMs locally and joining them into a Swarm cluster. Now it’s time to move it to the next level and create a cluster in AWS. Which tools should you use to do that? How should you set up your AWS Swarm cluster?
If you are like me, you already discarded the option to create servers manually through AWS Console, enter each with SSH, and run commands that will install Docker Engine and join the node with others. You know better than that and want a reliable and automated process that will create and maintain the cluster.
Among a myriad of options, we can choose from to create a Docker Swarm cluster in AWS, three stick from the crowd. We can use Docker Machine with AWS CLI, Docker for AWS as CloudFormation template, and Packer with Terraform. That is, by no means, the final list of the tools we can use. The time is limited and I promised to myself that this article will be shorter than War and Peace so I had to draw the line somewhere. Those three combinations are, in my opinion, the best candidates as your tools of choice. Even if you do choose something else, this article, hopefully, gave you an insight into the direction you might want to take.
