EcsCompose

This is a work in progress!

This gem attempts to provide a docker-compose-like interface to Amazon EC2 Container Service (ECS). It takes a docker-compose.yml file, and uses the included container definitions to update an ECS task definition and an ECS service.

This is still somewhat rudimentary, and the command-line interface is subject to change.

Add this line to your application's Gemfile:

gem 'ecs_compose'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install ecs_compose

Using the Amazon Web Services console, create a new ECS cluster and define a service my-service. Describe your service using a standard docker-compose.yml file. Then run:

ecs-compose -i service:my-service up

This will update the task definition my-service, and then update the running copy of my-service to the new task definition. The -i argument specifies the ECS task type (a one-shot task, or a persistent service, as well as a value to use as the task definiton name and family name on ECS.

There's also a "manifest" mode that allows you to work with multiple docker-compose.yml files, each defining a different service or task.

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment. Run bundle exec ecs_compose to use the gem in this directory, ignoring other installed copies of this gem.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
