Support Create Before Destroy #157

Closed bhardister closed 3 years ago

bhardister commented 3 years ago

I found that if the min size is 2 and the desired capacity is 2, the instance refresh will terminate 1 instance first before launching the new one. When coded as follows:

instance_refresh = { strategy = "Rolling" preferences = { min_healthy_percentage = 100 } }

Shouldn't it launch a new active and terminate an instance only after the new one is in the LB TG and healthy?

I think you should ask this question in some AWS-specific forum (like StackOverflow). This is not related to the module.

https://docs.aws.amazon.com/autoscaling/ec2/userguide/asg-instance-refresh.html - here is official documentation by AWS.
