An elasticsearch docker-compose containers setup that is meant to be hosted on ECS.
- Use 5.2.2 branch for ElasticSearch 5.2.2

docker-compose up
Yup that's it.
Update push-tag.sample in the bin folder with your own docker registry repository.

Most of the legwork has already been done in the configurations so it should be fairly easy.
This blog post that I wrote runs through some of the details inside the files and configurations that you should have in the ECS and task definitions.
Also feel free to refer to ecs-task-definition.sample as a start to guide you.
