ECS stop instance

I've an ECS cluster with running one task for my backend instance. I would like to be able to stop/start the EC2 instance whenever I want. Is it possible?? I was trying to stop instance directly but it terminates after few second when stopped and after that new instance is created automatically. I tried to change the Auto Scale Group to match desired=min=0 capacity but when I do that the instance gets auto terminated. I just want to turn off the Ec2 instance when its not needed to be used but at the same time I want data to persist betweet turning on and off. I am fighting with this for a few days now and wasn't able to achieve my goals.

Also how to link EBS volume with VOLUME /root/.local/share/XYZ from docker file image to persist the data from the XYZ folder

I would suggest you to do modifications in autoscaling group, when you want to turn off instance put 0 in auto scaling and when you want to turn on change value in autoscaling,

... you can do that with aws cli , and you can shcdule the period also by putting aws cli command in cron job

Start/Stop instances and auto-scale don't really fit together.

Auto-scale is specifically designed to solve scalein/scaleout.

One way to address this could be using customized termination policy (but I never tried this in ECS setup).

One note though, if your customized termination policy never terminates the instances and you continue adding instances to keep always, you might get good amount EC2 bill.

I would suggest using EFS. Here is an article from AWS on how to persist data from ECS containers using EFS.
