References

Wanted to update my TF to all the latest things include AWS 3. I have ECS containers that depend on the volume block to mount an EFS volume on fargate. Version 2 has documentation on how to add volumes to aws_ecs_task_definition. Version 3 apparently has completely gutted that configuration block with no clear description of how to set up.

• Upgrade Guide has no mention of changes to ecs task definitons
• CHANGELOG also has no mention of changes to ecs task definitions
