Amazon ECS Supports tmpfs for Fargate and Managed Instances
🧰 Amazon Elastic Container Service now supports tmpfs mounts for Linux tasks running on AWS Fargate and Amazon ECS Managed Instances, extending functionality beyond the EC2 launch type. Tmpfs creates memory-backed filesystems exposed inside containers for fast temporary storage, caches, and short-lived secrets without writing to task storage. You enable it by adding a linuxParameters block with tmpfs entries in your task definition and specifying containerPath, size, and optional mountOptions; task definitions can be registered or updated via the console, AWS CLI, CloudFormation, or AWS CDK. This capability is available in all AWS Regions where ECS and Fargate are supported.
