Here is my LaunchConfiguration of my AutoScalingGroup in my ECS-Cluster - using cloudformation.
UpdatePolicy:
AutoScalingRollingUpdate:
MinInstancesInService: 1
MaxBatchSize: 1
PauseTime: PT15M
WaitOnResourceSignals: true
My issue with the current setup is, when I make changes to the ECS Host AMI it will result in each of the EC2 instances being shut down and replaced one at a time. This results in any/all ECS Services currently running being terminated even before the the new EC2 instance is created.
Is there a way to do this? Their documentation says nothing about achieving the behavior we want.
Any pointers or tips are appreciated.
