Green / Blue Canary Setup: HowTo? about terraform-concourse HOT 3 CLOSED

Hi @luis-nagaki , I assume you are referring to the bluegreen module used in the examples folder.

That is used to setup an ECS cluster where Concourse will run and it allows you to toggle between a blue and green autoscaling groups, so you can rollout updates in a controlled way. In short, if you have blue running and you want to rollout an update on the ECS nodes, you would make the necessary modifications to the green part and enable that one (by setting appropriate values to the green_max_size, green_min_size and green_desired_capacity variables). After green has started correctly you disable blue by setting blue_max_size, blue_min_size and blue_desired_capacity to 0.

You can find more information on how the bluegreen module works by checking its documentation here.

In any case, that's just an example of how to create an ECS cluster, but you can deploy Concourse with this module in any ECS cluster that you have already running.

@luis-nagaki Did you ever figure this one out? We've got everything working except that no instances get attached to the ELB.
