Docker Swarm for AWS (Terraform)

This is an open Docker Swarm for AWS deployment based on Terraform and custom supporting images.

Why?

This is using mostly public code images (Working on a replacement for l4controller) instead of the "hidden" images docker use and the containers can run on non musl libc hosts.
Docker just released the Docker for AWS as a fire and forget thing, no docs, no anything and while I have no docs yet, the "how it works" is there in the open as the code for everything is on github.

There is still some cleanup to do and add it to travis, tests, etc. but it works as is.

Project Components

Terraform:

• docker-swarm

For the VPC and ELB modules, you can BYO as long as it complies with the inputs and outputs. (I use something based on https://github.com/segmentio/stack that will publish soon)

Images:

• guide-aws This container guides the cluster instances through its lifecycle performing maintenance tasks.

• meta-aws Provides a simple Flask based metadata service, primarely gives Swarm tokens based on the EC2 instance SG.

• init-aws Initializes the EC2 instance, gets AWS info, inits or joins the Swarm, updates DynamoDB entry, etc.

• status-aws Provides a simple Flask based status endpoint based on the Docker Engine status.

• elb-aws Dynamically updates the cluster ELB based on the published services running on the cluster.

Documentation for each image is found under the image README.md

Development

Initialize

After cloning the repo, please run:

pip install pre-commit # If not installed
pre-commit install

Add your modules to the modules directory and then run terraform normally
