Will setting docker --storage-opt be deprecated?

Question

My batch jobs depend on increasing the disk space available to docker by setting --storage-opt in the launch template.  According to https://aws.amazon.com/premiumsupport/knowledge-center/increase-default-ecs-docker-limit this setting actually only applies to Amazon Linux 1 AMIs, which will soon be deprecated:  
  
_Important: This article is applicable if you're using Amazon Linux 1 AMIs to launch container instances in your ECS cluster. Amazon Linux 2 AMIs use the Docker overlay2 storage driver, which gives you a base storage size of the space left on your disk. Amazon Linux 1 will no longer be supported after December 31, 2020._  
  
I guess this means I am using a v1 AMI; how then do I select a v2 AMI?  I have never manually selected an AMI, I always use the defaults; in which case I am surprised that a soon-to-be-deprecated AMI is still the default.

Answer

It seems the reason this is occurring is because M4 instances use an Amazon Linux 1 AMI by default.  It is possible to set the AMI to a v2 AMI in the Batch compute environment setup -- you need to look up the specific AMI for your region though.  
  
It seems some instance types automatically pick a v2 AMI by default; hopefully this will be the case for M4 instances in the future as well.

Answer

note that with the recent support for AL2, you don't need to look it up anymore - just specify AL2
