AWS ECS scheduled scaling with terraform
We are using terraform to schedule more containers to ECS cluster
The problem is that a new deployment (terraform apply) will make the scheduled containers to be terminated
i.e if we schedule more containers to 15 PM and scale down to 20 PM, if we run terraform apply at 16 PM - the containers launched at 15 PM will be terminated
any suggestions?

I am not sure how it works for ECS, but I think it's quite similar to ASG. In ASG when terraform recreate it, there is no way to preserve the latest ASG scale out. We need to do it manually right after the terraform apply

We ended up scheduling the scale up action for every minute during that time
This means that if a new deployment is launched - it will be validated that the number of desired containers is right

Why is terraform used for the deployment as well? It makes sense to scale up using Terraform, but deploying through ECS can be done using just the aws cli which will leave your EC2 instances alone, using e.g. ecs-deploy (boto3) or ecs-deploy (shell)
