With ElasticLoadBalancingV2 we need to define a TargetGroup and our instances must be part of this TargetGroup. When we create our instances with EC2Fleet, we have no way to declare that we want them to be attached to some TargetGroup. The only way to attach these instances would be to have some lambda reacting to their creation and dynamically attaching them to some TargetGroup... that does not look like something we want to do and maintain. Since we only want two instances, let's switch to a more static approach that can then be integrated with TargetGroup.

Closing as we're really not confortable with that adoption stuff in cloud formation and don't want to accidentally kill our beloved EC2 instances. |
